-----
Aura of Despair (Su): The blackguard radiates a malign aura that causes enemies within 10 feet of him to take a –2 penalty on all saving throws.

Aura of Evil (Ex): The power of a blackguard’s aura of evil (see the detect evil spell) is equal to his blackguard level.

Command Undead (Su): He commands undead as 1st-level cleric. He gets a +2 bonus on turning checks due to Knowledge (religion).

Dark Blessing (Su): He applies his Charisma modifier (if positive) as a bonus on all saving throws.

Detect Good (Sp): A blackguard can use detect good as a spell-like ability, duplicating the effect of the detect good spell.

Protective Slime (Su): A slimy red jelly coats the babau’s skin. Any weapon that touches it takes 1d8 points of acid damage from the corrosive goo, and the weapon’s hardness does not reduce this damage. A magic weapon may attempt a DC 19 Reflex save to avoid taking this damage. A creature who strikes the babau with an unarmed attack, unarmed strike, touch spell, or natural weapon takes this damage as well but can negate the damage with a DC 19 Reflex save. The save DCs are Constitution-based.

Smite Good (Su): May attempt to smite good with one normal melee attack. He adds his Charisma modifier (if positive) to his attack roll and deals 3 extra points of damage. If he accidentally smites a creature that is not good, the smite has no effect but it is still used up for that day.

Summon Demon (Sp): Once per day a babau can attempt to summon 1 babau with a 40% chance of success. This ability is the equivalent of a 3rd-level spell.

Skills: Babaus have a +8 racial bonus on Hide, Listen, Move Silently, and Search checks.[/sblock]

The Hellfoot Clan

The Hellfoot Clan was a "random" encounter in a recent adventure I ran. The PCs defeated them somewhat easily, but Dagda and one other bandit escaped.

Other Treasure: In addition to personally carried items, each bandit carries 3 pp, 6 gp, 10 sp, and 6 cp. Dagda carries 6 pp, 5 gp, 11 sp, and 1 cp.

I really like your oozes. My next campaign is going to include FR's Ghaunadaur as one of the main villains so consider these critters yoinked. I hope to see the fluff for them soon.

Glad you liked them. I've put up a short history for the Soft Corps. I'll get around to brief personality descriptions sooner or later. I also stuck the Hellfoot Clan in an empty post.

BTW, work still continues on that troglodyte wereconstrictor.

The Mountain King

The Mountain King was an NPC in a recent adventure I ran. The PCs had to negotiate passage with the Mountain King while en route to the main adventure site in order to free the enslaved kinsmen of one of the party's followers. The PCs handled the encounter with much tact, which was a wise move since the Mountain King and his personal guard could've inflicted a TPK if provoked.

Aura of Fear (Su): Enemies within 20 ft. take a -2 morale penalty on all saving throws for as long as they remain in range. The aura lasts for 5 rounds.

Body Adjustment (Psi): Heals 2d12 points of damage to manifester. Manifesting time is 1 round.

Brain Lock (Psi): The duration of this ability is Concentration plus 1 round. The subject stands dazed, unable to take any psionic actions (including manifesting powers or using psionic feats that require a decision to be used) nor any mental actions at all. A brain locked subject is not stunned, so attackers get no special advantage against him. A brain locked flyer must descend to the closest safe level area below it. An air-breathing swimmer must make for the surface.

Cruelest Cut (Ex): Inflicts an additional 1d4 points of Constitution damage with a melee attack.

Defensive Precognition (Psi): Gain a +2 insight bonus to AC and all saves for 6 minutes.

Empty Mind (Psi): Gain a +4 bonus on all Will saves until next action. Can manifest this power as an immediate action.

Force Screen (Psi): The force screen provides a +5 shield bonus to Armor Class (which applies against incorporeal touch attacks, since the force screen is a force effect). It lasts 6 minutes.

Mind Thrust (Psi): Inflicts 6d10 points of damage at a range of 40 ft.

Naturally Psionic (Ex): A phrenic creature gains 1 bonus power point.[/sblock]

The Deep Mother

The Deep Mother was the BBEG in a recent adventure I ran. She laired in a watery, disease-infested, filth-strewn series of caves. Therein she engaged in unholy rites to Incabulos in efforts to breed plague-carrying fiendish skum. The PCs defeated her minions and drove her off, but only after losing two party members.

-----
Enslave (Su): Three times per day, an aboleth can attempt to enslave any one living creature within 30 feet. The target must succeed on a DC 22 Will save or be affected as though by a dominate person spell (caster level 16th). An enslaved creature obeys the aboleth’s telepathic commands until freed by remove curse, and can attempt a new Will save every 24 hours to break free. The control is also broken if the aboleth dies or travels more than 1 mile from its slave. The save DC is Charisma-based.

Mucus Cloud (Ex): An aboleth underwater surrounds itself with a viscous cloud of mucus roughly 1 foot thick. Any creature coming into contact with and inhaling this substance must succeed on a DC 23 Fortitude save or lose the ability to breathe air for the next 3 hours. An affected creature suffocates in 2d6 minutes if removed from the water. Renewed contact with the mucus cloud and failing another Fortitude save continues the effect for another 3 hours. The save DC is Constitution-based.

Slime (Ex): A blow from an aboleth’s tentacle can cause a terrible affliction. A creature hit by a tentacle must succeed on a DC 23 Fortitude save or begin to transform over the next 1d4+1 minutes, the skin gradually becoming a clear, slimy membrane. An afflicted creature must remain moistened with cool, fresh water or take 1d12 points of damage every 10 minutes. The slime reduces the creature’s natural armor bonus by 1 (but never to less than 0). The save DC is Constitution-based.

A remove disease spell cast before the transformation is complete will restore an afflicted creature to normal. Afterward, however, only a heal or mass heal spell can reverse the affliction.

Skills: An aboleth has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.[/sblock]

Lupigriff Riders

I created this gang of lupigriff riders for a recent adventure I ran, but the PCs never encountered them. In retrospect, I decided the encounter would've just been too difficult for the party. Maybe I'll use them some other time.

-----
Carrying Capacity: A light load for a lupigriff is up to 87 pounds; a medium load, 88-174 pounds; and a heavy load, 175-263 pounds.

Screech (Ex): As a standard action, a lupigriff may unleash a piercing screech. This sonic attack affects all creatures in a 10-foot cone. Creatures in the area of effect must make a DC 14 Fortitude save or be stunned for 1 round. A stunned character can’t act, loses any Dexterity bonus to AC, and takes a –2 penalty to AC. The save DC is Constitution-based.

Skills: Lupigriffs have a +2 racial bonus on Listen checks and a +5 racial bonus on Spot checks. They have a +1 racial bonus on Move Silently, and a +2 racial bonus on Hide checks. Lupigriffs have a +4 racial bonus on Survival checks when tracking by scent.

Training a Lupigriff: A lupigriff requires training before it can bear a rider in combat. Training a lupigriff requires six weeks of work and a DC 25 Handle Animal check. Riding a lupigriff requires an exotic saddle. A lupigriff can fight while carrying a rider, but the rider cannot also attack unless he succeeds on a Ride check. Lupigriff eggs are worth 1,000 gp apiece on the open market, while young are worth 1,500 gp each. Professional trainers charge 500 gp to rear or train a lupigriff.[/sblock]

Airamis

I don't picture Airamis as being a dedicated villain. Likewise, he isn't going to terribly devoted to the cause of good. He could throw in his lot with a bad guy, working for money and prestige, only to turn against his employer when the going gets too tough.

Breath Weapon (Su): A mephit can use its breath weapon once every 1d4 rounds as a standard action. 15-foot cone of dust and grit, damage 1d8, Reflex DC 15 half. The save DC is Constitution-based and includes a +1 racial bonus.

Enhanced Mobility (Ex): When wearing no armor and not using a shield, a duelist gains an additional +4 bonus to AC against attacks of opportunity caused when he moves out of a threatened square.

Fast Healing (Ex): Mephits heal 2 points of damage each round, provided they are still alive and certain other conditions are met. An air mephit heals only if exposed to moving air, be it a breeze, a draft, a spell effect, or even the mephit fanning itself.

Precise Strike (Ex): At 5th level, a duelist gains the ability to strike precisely with a light or one-handed piercing weapon, gaining an extra 1d6 damage added to his normal damage roll. When making a precise strike, he cannot attack with a weapon in his other hand or use a shield. His precise strike only works against living creatures with discernible anatomies. Any creature that is immune to critical hits is not vulnerable to a precise strike, and any item or ability that protects a creature from critical hits also protects a creature from a precise strike.

Summon Mephit (Sp): Once per day, a mephit can attempt to summon another mephit of the same variety, much as though casting a summon monster spell, but with only a 25% chance of success. Roll d%: On a failure, no creature answers the summons that day. A mephit that has just been summoned cannot use its own summon ability for 1 hour. This ability is the equivalent of a 2nd–level spell.[/sblock]

Blindsense (Ex): A shark can locate creatures underwater within a 30-foot radius. This ability works only when the shark is underwater.

Breath Weapon (Su): Once per day, this monster breathes a 60-foot-line of lightning. A half-dragon’s breath weapon deals 6d8 points of damage. A successful Reflex save (DC 15) reduces damage by half.

Single Actions Only (Ex): Zombies have poor reflexes and can perform only a single move action or attack action each round. A zombie can move up to its speed and attack in the same round, but only if it attempts a charge.

Skills: A half-dragon shark zombie has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.[/sblock]

Covey of Hags

I've always liked hags in D&D. Here's a covey of hags designed to function in a network of flooded sea caves. For added challenge, guard the covey with 1d8 merrow and 1d4 aquatic hill giants. For the aquatic hill giants, just add the aquatic subtype, a 40 ft. swim speed, and Swim +7 to the skill list. No need to change the CR.

BTW, I cheated a bit on the annis. She shouldn't be able to meet the prereq for Improved Swimming with just her annis HD. I don't think a 1 rank nudge unbalances her build.

Rake (Ex): Attack bonus +18 melee, damage 1d6+8. An annis can attack a grappled foe with both claws at no penalty.

Rend (Ex): An annis that hits with both claw attacks latches onto the opponent’s body and tears the flesh. This attack automatically deals an extra 2d6+12 points of damage.

Wild Aspect (Su): For 4 minutes, grants primary shark bite attack and the ability to breathe water.[/sblock]

Amphibious (Ex): Although sea hags are aquatic, they can survive indefinitely on land.

Evil Eye (Su): Three times per day, a sea hag can cast its dire gaze upon any single creature within 30 feet. The target must succeed on a DC 16 Will save or be dazed for three days, although remove curse or dispel evil can restore sanity sooner. In addition, an affected creature must succeed on a DC 16 Fortitude save or die from fright. Creatures with immunity to fear effects are not affected by the sea hag’s evil eye. The save DCs are Charisma-based.

Horrific Appearance (Su): The sight of a sea hag is so revolting that anyone (other than another hag) who sets eyes upon one must succeed on a DC 16 Fortitude save or instantly be weakened, taking 2d6 points of Strength damage. This damage cannot reduce a victim’s Strength score below 0, but anyone reduced to Strength 0 is helpless. Creatures that are affected by this power or that successfully save against it cannot be affected again by the same hag’s horrific appearance for 24 hours. The save DC is Charisma-based.

Skills: A sea hag has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.[/sblock]

Terrain Mastery: Grants +1 insight bonus on attack and damage rolls against aquatic, forest, hill, marsh, and underground creatures.

Weakness (Su): A green hag can weaken a foe by making a special touch attack. The opponent must succeed on a DC 17 Fortitude save or take 2d4 points of Strength damage. The save DC is Charisma-based.

Skills: A green hag has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.[/sblock]
[sblock=Covey Spell-Like Abilities] 3/day - animate dead, bestow curse (DC 17), control weather, dream, forcecage, mind blank, mirage arcana (DC 18), polymorph, veil (DC 19), vision. Caster level 9th. The save DCs are based on a Charisma score of 16. To use one of these abilities (which requires a full-round action), all three hags must be within 10 feet of one another, and all must participate. Once per month, a covey that does not have a hag eye can create one from a gem worth at least 20 gp.

Hag Eye: A hag eye is a magic gem created by a covey. It appears to be nothing more than a semiprecious stone, but a gem of seeing or other such effect reveals it as a disembodied eye. Often, a hag eye is worn as a ring, brooch, or other adornment. Any of the three hags who created the hag eye can see through it whenever they wish, so long as it is on the same plane of existence as the hag. A hag eye has hardness 5 and 10 hit points.

Destroying a hag eye deals 1d10 points of damage to each member of the covey and causes the one who sustained the greatest damage to be blinded for 24 hours.[/sblock]
