My next project (#4)!

leaving us with this:

Construction
Building a CONSTRUCT is expensive and time consuming, but nowhere near as demanding as the creation process for more powerful constructs. The physical body is a wood and iron framework that must be built before the magical animation can take place. The creation process takes four weeks and requires materials costing 500 gp. Creating the body requires a DC 15 Craft (blacksmithing) check and a DC 15 Craft (carpentry) check.
CL 11th; Craft Construct, animate objects, bull's strength and mount, caster must be at least 11th level; Price 8,000 gp; Cost 4,500 gp + 160 XP.

Good now?

Good indeed.

How about this remaining section, anything odd in there?:

Riding a CONSTRUCT
CONSTRUCTs offer several advantages in combat. they move faster than most Medium-size humanoids, offer substantial cover to a rider and allow most characters, especially spell casters, to do more in a round of combat.
Arcane Spell Failure: A CONSTRUCT confines a rider much like a suit of armour. The rider suffers an arcane spell failure chance of 20%, which stacks with any arcane spell failure chance from armour and shields.
Cover: CONSTRUCTs provide the rider with one-half cover, granting a +4 cover bonus to armour class and a +2 cover bonus on Reflex saves. An attack that misses the rider within the margin provided by cover instead hits the CONSTRUCT, provided that the attack roll is at least equal to the CONSTRUCT's armour class.

Well, I think there is not such thing as one-half cover in 3.5. The closest thing is soft cover, which is provided only by creatures, and gives +4 to AC but no reflex bonus. I think soft cover should replace one-half cover in the text.
Also, the rule for hitting the cover instead of the target is optional in 3.5, unlike in 3.0 (if I remember correctly)

And, just to get things squared away, here are the remaining special abilities related queries for this source:

15.
Adhesive Orb (Su): In lieu of its normal melee attacks, the CONSTRUCT can hurl a two foot diameter orb of hot, sticky tar at a single target up to 20-ft. away. It strikes as a ranged touch attack causing 2d6+10 points of damage. Furthermore, the tar adheres to the target's armour, severely hampering the creature's movement and combat abilities. It reduces the target's movement by 10-ft., and it also imposes a circumstance penalty to armoured opponent's AC equal to half the armour's bonus, ignoring any enhancement. For instance, a target wearing a suit of +1 chainmail suffers a -2 circumstance penalty because the chain mail normally bestows a +5 armour bonus. The orbs do not effect spells such as mage armour nor does it effect
natural armour bonuses. It lasts for one minute before dissipating.

Too complicated for my taste. What about this:

"Adhesive Orb (Su): In lieu of its normal melee attacks, the CONSTRUCT can hurl a two foot diameter orb of hot, sticky tar at a single target up to 20-ft. away. It strikes as a ranged touch attack causing 2d6+10 points of damage. Furthermore, the tar adheres to the target's armour, severely hampering the creature's movement and combat abilities: the target is entangled for 2d6 rounds"

Other thing, 2d6 base damage seems a bit high for hot tar. OTOH, if the tar were "extremely hot", then the damage could be 2d6 fire damage plus the CONSTRUCT Str bonus. (Which should be 30 in this case)

Weapon Adhesion (Ex): Whenever a slashing or bludgeoning weapon hit an CONSTRUCT, the creature's tar adheres to the weapon's blade or head. Because of tar accumulating on the weapon, its effectiveness diminishes as the combat progresses. Until the wielder cleans his weapon as a full round action that provokes an attack of opportunity, it suffers a cumulative -2 penalty to damage for every successful hit.

I don't like this ability. I would replace it with an ability like that of the Farastus (Fiend Folio)that makes weapons that hit him stuck unless the wielder makes a Reflex save.

Construction
An CONSTRUCT's construction requires 1,000 pounds of rock and 250 pounds of tar. It costs 75,000 gp to create, including 2,500 gp for its body. Creating the body requires a successful Craft (sculpting or masonry) check (DC 19). The creator must be 16th level and able to cast arcane spells. Completing the ritual drains 1,800 XP from the creator and requires geas/quest, limited wish, polymorph any object and web.

75,000-2,500=72,500
72,500*2=145,000 (market price)
145,000/25= 5800 (XP cost)

It seems this construct differs a lot from the basic formula of XP cost = market price /25

16.
Phase Slash (Su): As a free action, the BIRD can become incorporeal and try to slam a victim with a touch attack. If the attack is successful, the victim must roll a Fortitude save (DC 16) or be stunned for Id4 rounds, disoriented by the creature passing through him. The BIRD can maintain this state for only one round and can not use it again until 1 d6 rounds later. While the creature is incorporeal, it is immune to all physical attacks except those made by magic weapons or spells.

I'd split this ability into 2: one that lets the BIRD become incorporeal for 1 round, and other that lets it make the stunning attack while incorporeal.
My guess is that the fortitude DC to avoid stunning should be Str based.
The last sentence is not needed. ("While the creature is incorporeal, it is...)

Transparent (Su): Three times per day, the BIRD becomes transparent, giving it a +10 bonus to Hide checks if moving, and +15 if it remains immobile. It can maintain this state indefinitely, but becomes opaque again after dealing its first attack, as it cannot concentrate on both remaining transparent and engaging in combat.

What about:
"Transparent (Su): Three times per day, the BIRD can become transparent, giving it a +10 enhancement bonus to hide checks. It can maintain this state indefinitely, but it becomes opaque again if it takes a standard action or a full-round action, as it cannot concentrate on both remaining transparent and engaging in difficult activities (need a better expression)"

17.
Shocking Grasp (Sp): Once every three rounds, a THING can send a shocking bolt of electricity through its tail-pincer. This deals an automatic ld.8+1 points of damage to a victim grabbed by the tail-pincer; the THING can alternately make a touch attack with its tail-pincer to affect an opponent not already held.

Maybe this:
"Shocking grasp (Sp): Once every three rounds, a THING can send a shocking bolt of electricity through its tail-pincer as a swift action. This functions as the shocking grasp spell (caster level 1). This deals automatic damage to a victim grabbed by the tail-pincer"

18.
Full Attack: 2 Kama +5 melee (1d6+3/1d6+2), kama +5 melee (1d6+3) and claw +5 melee (1d4+2) or 2 claws +5 melee (1d4+3/1d4+2) and bite +3 melee (1d6+3)

Absolute Ambidexterity (Ex): DUDEs can strike as naturally with a weapon in each hand as they can with both claws. They suffer no penalty for fighting with two weapons. They may also attack with one claw and one weapon without penalty.

The full attack is weird, but first I'd change absolute ambidexterity to make it more "absolute" (other possibility was to change the name, but...)
"Absolute ambidexterity (Ex): DUDES can strike as naturally with a weapon in each hand as they can with both claws. They suffer no penalty for fighting with multiple weapons, just like if all his arms were primary. They also suffer no penalty for fighting with a combination of manufactured weapons and claws, i.e. they are considered to have Improved multiattack for their claws (but not for their bites)"

"Full attack: 3 Kamas +5 melee (1d6+3), and claw +5 (1d4+3), and bite +3 (1d6+1) "

(does he have multiattack?)

Well, I think there is not such thing as one-half cover in 3.5. The closest thing is soft cover, which is provided only by creatures, and gives +4 to AC but no reflex bonus. I think soft cover should replace one-half cover in the text.
Also, the rule for hitting the cover instead of the target is optional in 3.5, unlike in 3.0 (if I remember correctly)

cool. Didn’t really see anything there about hitting the cover, so I rewrote it like so:

Cover: A CONSTRUCT provides its rider with soft cover, granting a +4 bonus to armour class.

Does the rest look good then?

how about this. Instead of 2d6+10 (its Str is 31), I could split it up into 1d6+10 damage, and 1d6 fire damage?

I like the idea of changing that to entangling instead of all those crazy modifiers. Let me clarify a few of those items:

Adhesive Orb (Su): As a standard action, a CONSTRUCT can hurl a two-foot diameter orb of hot, sticky tar at a single target up to 20 feet away. This strikes as a ranged touch attack and deals 1d6+10 points of damage plus 1d6 points of fire damage. Furthermore, the tar adheres to the target's armour, causing the target to be entangled for 2d6 rounds.

Because of tar accumulating on the weapon, its effectiveness diminishes as the combat progresses.

I don't like this ability. I would replace it with an ability like that of the Farastus (Fiend Folio)that makes weapons that hit him stuck unless the wielder makes a Reflex save.

ah yes, good old “tarry”. sure, I’ll go with your idea. this ability is OK as written, I suppose, but weapons sticking to the creature sounds cooler.

Weapon Adhesion (Ex): The thick tar that composes an CONSTRUCT acts as a powerful adhesive, holding fast items that touch it. A weapon that strikes a CONSTRUCT is stuck fast unless the weilder succeeds on a DC X Reflex save. Pyring off a stuck weapon requires a DC X Strength check. The save and check DCs are (Strength?)-based.


Construction
An CONSTRUCT's construction requires 1,000 pounds of rock and 250 pounds of tar. It costs 75,000 gp to create, including 2,500 gp for its body. Creating the body requires a successful Craft (sculpting or masonry) check (DC 19). The creator must be 16th level and able to cast arcane spells. Completing the ritual drains 1,800 XP from the creator and requires geas/quest, limited wish, polymorph any object and web.

75,000-2,500=72,500
72,500*2=145,000 (market price)
145,000/25= 5800 (XP cost)

It seems this construct differs a lot from the basic formula of XP cost = market price /25

is that a fixed formula or just an estimate?

Construction
An CONSTRUCT's construction requires 1,000 pounds of rock and 250 pounds of tar. The materials to construct the body cost 2,500 gp. Creating the body requires a DC 19 Craft (sculpting) check or a DC 19 Craft (masonry) check.
CL 16th; Craft Construct, geas/quest, limited wish, polymorph any object, web, caster must be at least 16th level; Price 145,000 gp; Cost 75,000 gp + 1,800 XP.

If the attack is successful, the victim must roll a Fortitude save (DC 16) or be stunned for Id4 rounds, disoriented by the creature passing through him.

My guess is that the fortitude DC to avoid stunning should be Str based.
The last sentence is not needed. ("While the creature is incorporeal, it is...)

given that incorporeal creatures have no Str score, I have to disagree. given the numbers, it seems to be Dex-based, and since incorporeals use their Dex instead of Str on attack rolls, I guess that makes some sense?
actually, I may not need to split it into two abilities. How about this:

Phase Slash (Su): As a free action, a BIRD can become incorporeal for one round. In this state it has no Strength score and loses its normal attacks, but gains a touch attack. The touch attack deals no damage, but a victim hit by it must succeed on a DC X Fortitude save or be stunned for 1d4 rounds. The save DC is (Dexterity?)-based. A BIRD may use this ability once every 1d6 rounds.


Transparent (Su): Three times per day, the BIRD becomes transparent, giving it a +10 bonus to Hide checks if moving, and +15 if it remains immobile. It can maintain this state indefinitely, but becomes opaque again after dealing its first attack, as it cannot concentrate on both remaining transparent and engaging in combat.

What about:
"Transparent (Su): Three times per day, the BIRD can become transparent, giving it a +10 enhancement bonus to hide checks. It can maintain this state indefinitely, but it becomes opaque again if it takes a standard action or a full-round action, as it cannot concentrate on both remaining transparent and engaging in difficult activities (need a better expression)"

what about forcing a Concentration check to remain transparent if it attacks?


17.
Shocking Grasp (Sp): Once every three rounds, a THING can send a shocking bolt of electricity through its tail-pincer. This deals an automatic ld.8+1 points of damage to a victim grabbed by the tail-pincer; the THING can alternately make a touch attack with its tail-pincer to affect an opponent not already held.

What is a “swift action”? I know I’ve seen that somewhere before. So you know, it grapples and constricts with the tail-pincer. I think it should be useable through any contact: touch attack, melee attack, or grapple.


18.
Full Attack: 2 Kama +5 melee (1d6+3/1d6+2), kama +5 melee (1d6+3) and claw +5 melee (1d4+2) or 2 claws +5 melee (1d4+3/1d4+2) and bite +3 melee (1d6+3)

Absolute Ambidexterity (Ex): DUDEs can strike as naturally with a weapon in each hand as they can with both claws. They suffer no penalty for fighting with two weapons. They may also attack with one claw and one weapon without penalty.

sure does! And exotic weapon proficiency for the kama. Where is Improved Multiattack from, because I’m not sure if I can use it.

cool. Didn?t really see anything there about hitting the cover, so I rewrote it like so:

Cover: A CONSTRUCT provides its rider with soft cover, granting a +4 bonus to armour class.

Does the rest look good then?

There are some things that may be worth adding, like saying that the rider cannot make use of Evasion since is so confined, but generally it seems to be OK.

15.
how about this. Instead of 2d6+10 (its Str is 31), I could split it up into 1d6+10 damage,
and 1d6 fire damage?

Great

ah yes, good old ?tarry?. sure, I?ll go with your idea. this ability is OK as written, I suppose, but weapons sticking to the creature sounds cooler.

Glad you liked the idea.

Weapon Adhesion (Ex): The thick tar that composes an CONSTRUCT acts as a powerful adhesive, holding fast items that touch it. A weapon that strikes a CONSTRUCT is stuck fast unless the weilder succeeds on a DC X Reflex save. Pyring off a stuck weapon requires a DC X Strength check. The save and check DCs are (Strength?)-based.

The farastu's "Adhesive slime" is con-based. And even if the construct has a Con score of - I'd go with that: their HD should suffice.
By the way, I was never quite sure how prying off the weapon was supposed to work. You make a touch attack followed by the strength check? does that provokes an AoO? Or do you make a reflex save, and if you fail you are entitled to the Str check?

is that a fixed formula or just an estimate?

To enchant a construct, a spellcaster must spend 1/25 the item?s price in XP [...]

16.
Phase Slash (Su): As a free action, the BIRD can become incorporeal and try to slam a victim with a touch attack.

The touch attack deals no damage, but a victim hit by it must succeed on a DC X Fortitude save or be stunned for 1d4 rounds. The save DC is (Dexterity?)-based. A BIRD may use this ability once every 1d6 rounds.

I agree with your disagreement , and with the new Phase Slash entry.

Transparent (Su): Three times per day, the BIRD becomes transparent, giving it a +10 bonus to Hide checks if moving, and +15 if it remains immobile. It can maintain this state indefinitely, but becomes opaque again after dealing its first attack, as it cannot concentrate on both remaining transparent and engaging in combat.

what about forcing a Concentration check to remain transparent if it attacks?

That is a very good idea, although I would enforce a concentration check in more situation than just attacking. Also, note that giving an extra bonus to hide for being immobile is an overkill, since the BIRD will already have a hide bonus for not moving.

17.
What is a ?swift action?? I know I?ve seen that somewhere before. So you know, it grapples and constricts with the tail-pincer. I think it should be useable through any contact: touch attack, melee attack, or grapple.

The definition of swift and immediate actions appears in the expanded psionic handbook (and I think that is OGL, if that matters). A swift action is a free action, that you cannot use more than once per round. (Just like a quickened spell)

What I am not sure is if a touch attack spell is not already discharged with any contact.

18.
sure does! And exotic weapon proficiency for the kama. Where is Improved Multiattack from, because I?m not sure if I can use it.

It appears in the EpicFeats rtf of the SRD, at the end, in the section of non-epic feats.
It also appears in the Draconomicon.
(Now that I think about this, the mention of Improved Multiattack may be misleading, since secondary weapons still add only half the strength bonus)

why would you need to make a touch attack before the Strength check? I think the rules assume that your hands remain in the weapon unless you choose to remove them, or are forced by other circumstances (say, the creature runs away from you).

Lookin good?

Weapon Adhesion (Ex): The thick tar that composes an CONSTRUCT acts as a powerful adhesive, holding fast items that touch it. A weapon that strikes a CONSTRUCT is stuck fast unless the wielder succeeds on a DC 18 Reflex save. Prying off a stuck weapon requires a DC 18 Strength check. The save and check DCs are Constitution-based.


16.
what should the save DC be based on?

Phase Slash (Su): As a free action, a BIRD can become incorporeal for one round. In this state it has no Strength score and loses its normal attacks, but gains a touch attack. The touch attack deals no damage, but a victim hit by it must succeed on a DC X Fortitude save or be stunned for 1d4 rounds. The save DC is (Dexterity?)-based.

we can kill the second Hide bonus, that’s not a problem. How would you recommend writing up the Concentration check part?


17

The definition of swift and immediate actions appears in the expanded psionic handbook (and I think that is OGL, if that matters). A swift action is a free action, that you cannot use more than once per round. (Just like a quickened spell)

What I am not sure is if a touch attack spell is not already discharged with any contact.

ok, good that it is OGL, but since it’s not dealing with psionics directly, I’d rather not make people look it up. “free action, once per round” should be self-explanatory.

same here, OGL perhaps, but I’d rather not make people look it up. I’d rather just state the effects plainly.

I think the rules assume that your hands remain in the weapon unless you choose to remove them, or are forced by other circumstances (say, the creature runs away from you).

When I imagine how this ability looks, it seems that a creature whose weapon gets stuck leaves his guard down, but there is no mention on AoOs. That is why I thought that the creature may lose the grip on the weapon.

Weapon Adhesion (Ex): The thick tar that composes an CONSTRUCT acts as a powerful adhesive, holding fast items that touch it. A weapon that strikes a CONSTRUCT is stuck fast unless the wielder succeeds on a DC 18 Reflex save. Prying off a stuck weapon requires a DC 18 Strength check. The save and check DCs are Constitution-based.

Good.

16.
what should the save DC be based on?

Phase Slash (Su): As a free action, a BIRD can become incorporeal for one round. In this state it has no Strength score and loses its normal attacks, but gains a touch attack. The touch attack deals no damage, but a victim hit by it must succeed on a DC X Fortitude save or be stunned for 1d4 rounds. The save DC is (Dexterity?)-based. A BIRD may use this ability once every 1d6 rounds.

Dexterity seems the most appropiate choice as you said.

Transparent (Su): Three times per day, the BIRD becomes transparent, giving it a +10 bonus to Hide checks if moving, and +15 if it remains immobile. It can maintain this state indefinitely, but becomes opaque again after dealing its first attack, as it cannot concentrate on both remaining transparent and engaging in combat.

we can kill the second Hide bonus, that?s not a problem. How would you recommend writing up the Concentration check part?

This may require some DM adjudications, but I think this is nicer than a 15 line paragraph detailing all the particular cases:

"It can maintain this state indefinitely, but may become opaque again if it performs some activities: whenever the BIRD takes an action that requires attention (mostly all standard and full-round actions) it must make a concentration check (DC 15) or become opaque."

17
ok, good that it is OGL, but since it?s not dealing with psionics directly, I?d rather not make people look it up. ?free action, once per round? should be self-explanatory.


same here, OGL perhaps, but I?d rather not make people look it up. I?d rather just state the effects plainly.

That is a sensible approach. (But for what I heard, it seems that swift and immediate actions are now more "regular" vocabulary of D&D, since they are used for new spells. Complete arcane had them, IIRC)

can state that a bit more simply, but you’re on the right track. How about:

Transparent (Su): Three times per day, a BIRD can become transparent, giving it a +10 enhancement bonus to Hide checks. It can maintain this state indefinitely, if the BIRD attacks, takes a full-round action, or takes an action that requires attention it must succeed on a DC 15 Concentration check or return to its normal state.


17
Shocking Grasp (Sp): Once every three rounds, a THING can send a shocking bolt of electricity through its tail-pincer. This deals an automatic ld.8+1 points of damage to a victim grabbed by the tail-pincer; the THING can alternately make a touch attack with its tail-pincer to affect an opponent not already held.

Note on the swift action… since it can only use this attack once every three rounds, “free action once per round” is redundant anyway.

Shocking Grasp (Sp): Once every three rounds, a THING can send a shocking bolt of electricity through its tail-pincer as a free action. This functions as the shocking grasp spell (caster level 1st). A THING can use this ability through any contact with the tail-pincer, including touch attacks, melee attacks, or grappling.


18
Full Attack: 2 Kama +5 melee (1d6+3/1d6+2), kama +5 melee (1d6+3) and claw +5 melee (1d4+2) or 2 claws +5 melee (1d4+3/1d4+2) and bite +3 melee (1d6+3)

Absolute Ambidexterity (Ex): DUDEs can strike as naturally with a weapon in each hand as they can with both claws. They suffer no penalty for fighting with two weapons. They may also attack with one claw and one weapon without penalty.

How about this now:

Natural Ambidexterity (Ex): A DUDE can strike as naturally with a weapon in each hand as it can with both claws. A DUDE suffers no penalty for fighting with multiple natural weapons, as if all attacks were primary weapons. A DUDE also suffers no penalty for fighting with a combination of manufactured weapons and claws (but not its bite).

Full Attack: 3 kamas +5 melee (1d6+3), and claw +5 (1d4+3), and bite +3 (1d6+1)

I’m not completely confident about that line. In the original attack line, you see him attacking with 3 kamas (one with a separate attack value) and claw as one type of full attack, and for another type of full attack he can use both claws and a bite. the line you wrote there contradicts the natural ambidexterity.

It can maintain this state indefinitely, if the BIRD attacks, takes a full-round action, or takes an action that requires attention it must succeed on a DC 15 Concentration check or return to its normal state.

It looks almost done. ("almost" because i'd put a "but" in the start of ", if the BIRD attacks")

17
Note on the swift action? since it can only use this attack once every three rounds, ?free action once per round? is redundant anyway.

Shocking Grasp (Sp): Once every three rounds, a THING can send a shocking bolt of electricity through its tail-pincer as a free action. This functions as the shocking grasp spell (caster level 1st). A THING can use this ability through any contact with the tail-pincer, including touch attacks, melee attacks, or grappling.

I'd say this is done.

I?m not completely confident about that line. In the original attack line, you see him attacking with 3 kamas (one with a separate attack value) and claw as one type of full attack, and for another type of full attack he can use both claws and a bite. the line you wrote there contradicts the natural ambidexterity.

Certainly it contradicts the original ambidexterity, the thing is that I changed the ability because it didn't appear so "absolute" to me (maybe I do this too often?)

Nevertheless, according to the rules of 3.5, I can't see any reason why this DUDE couldn't make four attacks (claw/weapon combinations) and then a bite attack with the penalty for attacking with a secondary weapon (-2 with Multiattack, and half Str bonus to damage)

i'm not so sure that i would want this guy making that many attacks per round. that just a whole lot for something so low in HD.

(This is the first time I see a creature of the "humanoid" type with claws, or four arms, or a bonus of +8 natural. Is it not "Monstrous humanoid" more fitting?)

Well, the pounce ability makes the change I propose to ambidexterity more powerful, but even with that this creature doesn't seem unbalanced for, what, CR 3? (Look at the Temporal Filcher in the XPHB for a CR 3 creature with 6 attacks)
Also, you are right in that 5 attacks seem too much for a 3HD creature. But I feel the same way about the modifier to the ability scores and the natural armor, so I don't think there is an easy solution.
