Stun (Ex): A black slaad can make attack as if it had the Stunning Fist feat eleven times per day. The Fortitude save DC is 34. The black slaad can stun with its tongues as well as its claws.

Chaos Touch (Ex): On a successful tongue melee attack, the slaad deals 10d4 points of chaotic damage. Unless the chaos infecting the wound is somehow neutralized, it deals another 5d4 points of chaotic mage every subsequent round for 11 rounds.

Chaos Spittle (Ex): A black ad can spit a glob of chaos at any target it can see within 120 feet as a ranged touch attack. The chaos deals 20d4 points of chaos damage (no splash damage). Unless the chaos is somehow neutralized, the glob deals another 10d4 points of damage every subsequent round for 11 rounds.

Weaponbreaker (Ex): When a black slaad uses its Sunder feat, it rolls damage twice and takes the higher of the two rolls as the roll to break the weapon.

Spell-Like Abilities: At will - animate objects, circle of death, chaos hammer, cloak of chaos, death knell, deeper darkness, dispel law, fear, finger of death, fireball, fly, greater dispelling, identify, improved invisibility, lightning bolt, magic circle against law, plane shift, power word blind, power word kill, protection from law, see invisibility, shatter, teleport without error, word of chaos; 1/day - implosion, peripety, ruin, spell worm. Caster level 25th; save DC 20 + spell level.

Alternate Form (Su): A black slaad can shift between its natural and any humanoid form at will as a standard action.

A black slaad can remain in humanoid form indefinitely. The ability is otherwise similar to alter self cast by a 21st-level caster.

Summon Slaad (Sp): Three times per day a black slaad can attempt to summon 2-4 death slaadi (01-20 fails, 21-100 succeeds), or 1-2 white slaadi (01-60 fails, 61-100 succeeds).

Telepathy (Su): Black slaadi can communicate telepathically with any creature within 100 feet that has a language.

Chaotic Subtype

A subtype usually applied only to outsiders native to the chaotic-aligned Outer Planes. Most creatures that have this subtype also have chaotic alignments; however, if their alignments change they still retain the subtype. Any effect that depends on alignment affects a creature with this subtype as if the creature has a chaotic alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the chaotic subtype overcomes damage reduction as if its natural weapons and any weapons it wields were chaotic-aligned (see Damage Reduction).
