OGL "Mob" Type (People Swarm) New! More Dangerous! Manes! Zombies! Elementals! Oh My!

Ever since I was informed that a "Mob" Subtype exists in Dungeon 113, I've been enamored with the idea; since I'm needing something like that for my next session.

In response to some questions I had about how a Zombie mob would work, I've had to completely rethink how they'd work. I think I've found a better solution, albiet more challenging. My original work is in the small text quoted below.

I've completely redone some things, based on the questions I've gotten here. I had no good way to deal with the individuals of the mob, which is important when you're talking about villagers or manes or zombies, as opposed to bats and rats and wasps.

I'll list out the Mob Type here, and my reasonings will be in italics. Below, will be a few example mobs. If anyone had seen the previous posts, they'll notice they've really gone up in apparent power - my original effort was simply renamed swarms, and had no real 'oomph' to it (that you'd expect an angry mob to have)

---

A Mob is a single pool of creatures that act as one. A Mob can be consisted of Small or Medium creatures, and a single mob consists of 30 creatures. The Mob takes up a square 20 ft on a side, but is fluid, and can take any shape of contiguous squares, just lke a swarm.

The 30 creatures==Mob will be important later. There's about 2 creatures for every square in a Mob.

A Mob has a reach of zero feet. To attack, it must engulf it's target, provoking an AoO. Every time a Mob moves through an enemy-occupied square, it provokes an AoO. Mobs cannot be tripped, grappled, or bull rushed. A critical hit that would do sufficient damage to eliminate a single constituent creature of the mob "eliminates a Mob member", as detailed below.

I can see a critical removing a single mob member, but I don't see flanking/sneak attacking working, whether the rogue is inside the mob or outside.

A Mob takes half damage from single-target damage spells, and one-and-a-half times damage from area of effect damage spells. Other spells and effects that may disable, disband, or kill a single Mob member will "eliminate a Mob member", as detailed below.

A Scorching Ray might glance through 5 or 6 people as it passes through the mass, but the sheer number of people in a small area make Fireballs more fun.

A Mob acts as if it had the Improved Bull Rush and Improved Overrun feats. Once the Mob is dispersed, the single creatures do not retain these feats.

Eliminating a Mob Member: An attack, spell, or effect that would eliminate a Mob member (such as Turn Undead vs a Zombie Mob) will break off the number of singular creatures affected into single creatures (if they are not killed or destroyed). The Mob itself takes 2 negative levels (subtract 2 from it's Hit Die) per HD of the original member (Subtract 4 from the HD of a mob consisting of 2 HD Gnolls). This negative level does not effect the Mob's abilities or attacks in any way. A Mob that reaches 0 HD is dispersed into it's constituent creatures.

Originally, I said, "Subtract a number of HP equal to one of the mob's creature's HP total", but subtracting a Hit Die is the same thing, no? By subtracting 2 HD instead of 1, the Mob is dispersed when it's at about half strength.

Persistant Mob: A Persistant Mob is a Mob that will not halt combat once it has been dispersed, such as mindless undead. A Mob that is reduced to 0 HP is dispersed into 10 singular creatures, placed randomly or at the DM's discretion. A Mob stopped by Hit Die loss is dispersed into 10 creatures, placed randomly or at the DM's discretion.

As a rule of thumb, if detailed information is needed on the status of Mob members after the mob is dispersed by damage, 10 will be alive, 10 disabled/dying, and 10 dead.

Samples!

Angry Mob of Villagers (AMoV)
Gargantuan Humanoid (Mob)


Giving it Gargantuan size for it's 20ft spacing helps with Grappling. Mobs are good at that!

CR: 8?
HD: 30d8 (120 HP)
Init: +0
Speed: 30 ft
AC: 10 (Touch 10, Flatfooted 10)
Base Attack/Grapple: +25/+37
Attack: Pitchforks and Torches +25 (3d6)
Full Attack: Pitchforks and Torches +25/+20 (3d6)

You'll notice on the attack lines, I'm treating this kinda like an actual 30 HD creature, and getting rid of the 'automatic attack'. A high-level, high-AC PC should be able to duck and weave through a mob.

Saves: Fort +1, Ref +1, Will +10
Mob mentality boosts their Will saves.

Abilities: Str 10, Dex 10, Con 10, Wis 10, Int 10, Chr 10
Special Qualities: Torches!, "There it is!", "Let's Git'em!", Pile-on

An Angry Mob of Villagers is often encountered in towns beset by experimenting (and often mad) wizards and their creations.

Torches!: Half of an AMoV's damage is fire damage from their torches.
"There it is!": An AMoV gains an extra +10 to hit and 3d6 damage against constructs and aberrations.
"Let's Git'em!": Single humanoids must make a DC 14 Will save or be caught up in the mob. For every 2 humanoids that join the mob, the mob gains 1 HD (4 HP), +1 Attack, and +1 damage.

Pile-on: A mob that successfully grapples an opponent of Large or smaller size deals automatic damage each round the opponent is grappled. A mob can grapple 2 Large, 8 Medium, 16 Small, or 32 Tiny or smaller creatures at once, and may move normally while doing so.

In general, much more dangerous. This is a real mob that will tear apart unprepared opponents. A Flesh Golem, an AMoV's favored enemy (so to speak) won't last given average HP and damage, it looks.

Let's redo the Manes, as well:

Mobbing Pack of Manes (MPoM)
Gargantuan Outsider (Chaotic, Evil, Extraplanar, Tanar'ri, Mob, Persistant)


CR: 10?
HD: 30d8 (120 HP)
Init: +0
Speed: 20 ft
AC: 10 (Touch 10, Flatfooted 10)
Base Attack/Grapple: +25/+37
Attack: Claws +25 (2d6)
Full Attack: 2 Claws +25 (2d4) and Bite +20 (2d6)
Saves: Fort +2, Ref +2, Will -2
Abilities: Str 10, Dex 10, Con 11, Int -, Wis 3, Chr 3
Special Attacks: Death Throes
Special Qualities: DR 3/cold iron or good, darkvision 60ft, immunity to electricity and poison, mindless, resistance to acid, cold, fire 10, telepathy 100 ft., Persistant Mob, Pile-On

Death Throes: Every attack doing over 10 points of damage kills a member of the MPoM for every 10 points it does. Everyone within 10 ft of the killed individuals (DM discretion) takes 1d6 points of acid damage (Reflex DC 10 half) as the body erupts into a cloud of acidic vapor. Every member killed reduces the MPoM's HD by 2, as per the 'Eliminating a Mob Member' text.

Persistant Mob: A persistant mob continues to fight after dispersed; see the Mob type entry for details.

Pile-on: A mob that successfully grapples an opponent of Large or smaller size deals automatic damage each round the opponent is grappled. A mob can grapple 2 Large, 8 Medium, 16 Small, or 32 Tiny or smaller creatures at once, and may move normally while doing so.

Again, thanks to Pants for the converted Manes!

Here's Zombies for Matafuego:

Horde of Zombies (HoZ)
Gargantuan Undead (Mob, Persistant)


CR: 6?
HD: 30d12 (180 HP)
Init: +0
Speed: 20 ft
AC: 11 (Touch 9, Flatfooted 11)
Base Attack/Grapple: +17/+29
Attack: Slam +17 (2d8+8)
Full Attack: Slam +17 (2d8+8)

I decided to up the damage from the Strength modifier for Mobs.

Saves: Fort +0, Ref -1, Will +3
Abilities: Str 12, Dex 8, Con -, Int -, Wis 10, Chr 1
Special Attacks: Braaaiinnns!
Special Qualities: DR 5/slashing, Darkvision 60 ft, Undead Traits,
Persistant Mob, Pile-On

Braaaiinns!: A Zombie mob can attack an opponent it has engulfed even if it also moves in the same turn. (individual zombies have the Single Actions Only trait).

Persistant Mob: A persistant mob continues to fight after dispersed;
see the Mob type entry for details.

Pile-on: A mob that successfully grapples an opponent of Large or smaller size deals automatic damage each round the opponent is grappled. A mob can grapple 2 Large, 8 Medium, 16 Small, or 32 Tiny or smaller creatures at once, and may move normally while doing so.

And Evilhalfling's Bandit Mob with the new ideas:

Road Bandit Mob (RBM)
Gargantuan Humanoid (Mob)


CR: 12?
HD: 30d8+30 (150 HP)
Init: +1
Speed: 30 ft
AC: 13 (Touch 12, Flatfooted 12)
Base Attack/Grapple: +30/+42
Attack: Swords +30 (3d8+8)
Full Attack: Swords +30 (3d8+8)
Saves: Fort +3, Ref +3, Will +8
Abilities: Str 13, Dex 12, Con 12, Int 10, Wis 10, Chr 11
Special Attacks: Arrow Storm
Special Qualities: Woodland Movement, Pile-On

Arrow Storm: As a full-round attack, the RBM may fire a hail of arrows at a spot on the battlefield. This attack does 6d6 piercing damage in a 20 ft radius spread, at a range of up to 100 ft. (DC 15 Reflex save for half).

Woodland Movement: A RBM can move through non-magical foliage at full speed.

Pile-on: A mob that successfully grapples an opponent of Large or smaller size deals automatic damage each round the opponent is grappled. A mob can grapple 2 Large, 8 Medium, 16 Small, or 32 Tiny or smaller creatures at once, and may move normally while doing so.

I got me a Rock'n Roll Band:

Medium Earth Elemental Mob (MEEM)
Gargantuan Outsider (Mob, Extraplanar, Earth)


CR: A Lot.
HD: 120d8+360 (840 HP) (holy moly!)
Init: -1
Speed: 20 ft
AC: 18 (-1 Dex, +9 Natural), touch 9, flatfooted 18
BAB/Grapple: +21/+34

Attack: Slam +21 Melee 4d8+20
Full Attack: Slam +21 Melee 4d8+20

Saves: Fort +7, Ref +0, Will +1
Abilities: Str 21, Dex 8, Con 17, Int 4, Wis 11, Cha 11

Special Attacks: Earth Mastery, Push, Grind
Special Qualities: Elemental Traits. Darkvision 60, Earth Glide

No-one knows what occasionally causes elementals to band together into such a
cohesive unit, but it may be a mystery better left alone, as even the smallest
of elementals are a force to be reckoned with when moving as one.

Earth Mastery, Push, Earth Glide: As stated in the SRD.

Grind: Being caught in a mass of moving, grinding, writhing, live earth
is a terrible thing. If an opponent is engulfed by a MEEM and successfully
Pinned, they take double damage automatically each round until unpinned.

I don't even know what CR this is. Yea, it's a lot of HP. Medium Earth
Elementals are 4d8, so, times 30...eh. It could be cut in half easily I
suppose.

Fire Elementals would have the Immolate ability just like this, Water
Elementals the Drown, and Air Elementals Tornado. The Air needs
a better name.

This'd be a heck of an Epic Level Summon.


---

So, hopefully this is better. It's certainly more dangerous and powerful, which is what mobs should be. Plus, it gives a mechanic to send out 30 mooks against a mid-level party at a single CR 9 rather than 30 CR 1s, which I think
cuts down the XP handed out.

Again, thanks for reading. Let me know if you use them, and how it went!

Koewn's First Try at Mobs said:
[size=-2]
A Mob is a collection of Small and/or Medium creatures that act as a single creature. A Mob takes up a 20 by 20 ft area. It is consisted around 30 Medium sized creatures, 40 mixed Medium/Small creatures, or 50 Small creatures. A Mob is not subject to critical hits or flanking. A Mob takes half damage from targeted spells and ranged attacks. Mind-affecting effects must be able to effect the Mob's full HD to have effect. A Mob has a reach of 5 feet. If a creature is engulfed by the Mob, it automatically takes damage each round it is in the Mob.

A Mob's damage is as follows:

1-4 HD: 2d6
5-8 HD: 4d6
9-12 HD: 6d6
13-16 HD: 8d6
17-20 HD: 10d6
21+ HD: 12d6

Ok. Some Examples:

Angry Mob of Villagers

HD: 4d8 (18 HP)
Init: +0
Speed: 20 ft
AC: 10
BAB: +1
Attack: Pitchforks and Torches (2d6) or Mob (2d6)
Full Attack: Pitchforks and Torches (2d6) or Mob (2d6)
Special Attacks: Torches!, Mob
Special Qualities: Git'em!
Saves: Fort +1, Ref +1, Will +1
Abilities: Str 10, Dex 10, Con 10, Int 10, Wis 10, Chr 10
(Rest doesn't matter for this example)

Mob: A creature engulfed by the AMoV take automatic damage from the mob.
Torches! The pitchforks are pointy, but half of a AMoV's damage is fire damage from their torches.
Git'em!: An AMoV gains a +1 to attack rolls and 1d6 extra damage per 4 Hit Die versus Constructs and Aberrations.

OK. Next up:

Mobbing Pack of Manes

HD: 8d8 (36 HP)
Init: +1
Speed: 20 ft
AC: 14 (+3 Natural, +1 Dex)
BAB: +1
Attack: Claws and Bites +2 Melee (4d6) or Mob (4d6)
Full Attack: Claws and Bites +2 Melee (4d6) or Mob (4d6)
Special Attacks: Death Throes
Special Qualities: Damage reduction 3/cold iron or good, darkvision 60 ft., immunity to electricity and poison, mindless, resistance to acid 10, and cold 10 and fire 10, telepathy 100 ft.
Saves: Fort +2, Ref +2, Will -2
Abilities: Str 10, Dex 11, Con 11, Int -, Wis 3, Chr 3
(Rest doesn't matter for this example)

Death Throes: Any attack that causes more than 5 points of damage to a Mobbing Pack of Manes (MPoM) causes one of the constiuent Manes to die (per 5 pts dealt). It's body erupts into a noxious cloud of acidic vapor, dealing 1d6 points of acid damage to creatures within 10 ft (within 10 ft of what is up to the DM mostly). Creatures within the mob have no save, creatures outside the mob can make a DC 10 Reflex save for half.

I could see this having some great applications, such as trying to handle a riot in a major city, or taking part in a major battle in a war.

How would a mob interact with an opposing mob? And for guys like villagers, how much damage would you need to inflict upon the mob in order to get it to disperse?

How many hit dice does the mob have? It looks like 4x original hit dice, and the rest of the stats stay unchanged?

You could go a step farther and do mass combat this way.

A Unit is the same as a mob, but has 5x the hit dice of the base creatures, and does damage as d8s, not d6s. Their attacks and ACs are +2 from the original, due to unit cohesion and Aid Another.

Good enough for quick and dirty, anyway.

Where is the swarm type from originally, anyway?

I was looking for some "mob" rules... and I was thinking of applying the Swarm thing.
I'm needing a Mob of Zombies but my main concern is how would these interact with a Cleric Turn Undead ability...
 

This post is redundant now that I've redone the whole concept, but, here it remains.


I lost track of this thread, and missed all your guys' questions. Here's some answers:

rbingham2000 said:

Hm. Assuming they were the same sort of mob, say the Villagers, they'd engulf each other, do automatic damage to each other for a few rounds, and whoever rolled better damage would 'win' by dispersing the other mob.

rbingham2000 said:
...how much damage would you need to inflict upon the mob in order to get it to disperse?

Just like a swarm, it needs to be taken to 0 hitpoints. In the Villager case, taking that mob to 0 indicates the members of the mob have fled, surrendered, or given up, and are now no longer combatants.

There's an odd thing here though, which has to be resolved. I've got a example up there of a Mob of Manes.

Manes don't surrender - you're not going to disperse them. Undead, demons, devils, all sorts of cool stuff to make into a Mob may not ever give up!

Here's a quick footnote, then, to the Mob Subtype:

Persistant: A Persistant Mob is composed of singular creatures who by their very nature will not disperse 'peacefully'. When a Persistant Mob is brought to 0 hitpoints, it is replaced with 3d4 singular creatures of the Mob's type, placed in the squares the Mob originally occupied at random or DM discretion.

DanMCS said:
How many HD does the mob have?

As many as you give it, really. I gave my Villager Mob above 4 HD, my Manes Mob 8 HD. It really depends on what it consists of - I winged it, thinking about what sort of challenge I'd like to present the players with. If I get a chance to playtest this, I may be able to suss out the proper HD and CR for it.

DanMCS said:

Monster Manual 3.5, and it's in the SRD. There's several examples of Swarms in there, and people have been including more types in other products.

Matafuego said:

That's a tough call. In my Mob Type description, I said:

Koewn said:
Mind-affecting effects must be able to effect the Mob's full HD to have effect.

Treating the Mob as a single creature - let's pretend a Mob of 1HD Zombie Commoners would be...oh...6 Hit Die. If we just say 'turn the Hit Die', then it'd be like turning a 6 HD creature. *However*, that's a little off-base, as there's just too many zombies in that mob.

Here's what I would say:

Turning a Mob: A Cleric using Turn Undead against a Mob must make a Turning Check that will successfully turn the HD of a singular creature that makes up the Mob.

The Turning Damage roll is then applied against the Mob as Hit Point Damage if the cleric's level is sufficient enough to destroy the Mob's constituent undead. If the Cleric reduces the Mob to 0 HP, it is dispersed. A Persistant Mob (which disperses into 3d4 regular creatures), that is taken to -10 HP by a successful Turn Undead attempt is destroyed immediately and utterly (it does not disperse into single creatures).

OK: I'm of two minds on the 'fleeing' part of Turn Undead, here's an abstract version and a real version:


If a cleric is not of sufficient enough level to Destroy the Mob's constituent undead with their turning check, the Mob is slowed to half-speed, and may not approach the turning Cleric. Attack rolls against the Mob gain a +2 bonus, and the Mob does half-damage on normal attacks and it's automatic damage.

--- OR ---

If a cleric is not of sufficient enough level to Destroy the Mob's constituent undead with their turning check, the Mob seperates. Break off a number of single undead of the Mob's same type equal to the number of creatures the cleric would have turned - those undead will now act as single creatures, and flee as per the Turning rules. Do HP damage to the Mob equal to half the Cleric's Turning Damage.

Blah. I like the abstract version better from a DM perspective, but the other one is slightly more realistic, I guess. I've always hated dorking about with 'fleeing' undead. The moral here is to only throw Mobs your party cleric can Destroy at your players, so that things are easier on you. :)

Thanks for the questions! I'll try and codify the thoughts I've had into the main post, and also make up a Zombie Mob as well, sometime this week.

Excellent work. Any chance this could be broken down into a typical MM template?

Swarm was never really a template, so guidelines for this are probably the best result possible.

It should have reach like its component creatures. Swarms have no reach because the critters that make them up have no reach, really.

I like making it a gargantuan creature - takes care of grappling and gang tactic attacks.
