QUALITIES

Power Attack (ex) - A Black Dragon (Great Wyrm) may choose to take a penalty to its attack roll (up to -5). For each point of penalty, the Black Dragon (Great Wyrm) does one extra point of damage. The Black Dragon (Great Wyrm) must decide to use power attack at the beginning of its turn and it applies to all attack made until the start of its next turn.

Water Breathing (ex) - The creature can breathe under water.

Swamp Stride (ex) - This creature can move through difficult terrain at full speed in swamps.

Speak with Reptiles (sp) - This creature has the ability to speak with reptiles. This functions like speak with animals, but is limited to repiles.

ACTIONS
Attacks

Crush (ex) - This dragon can land on foes as a standard action, using its whole body to crush them. Crush attacks are effective only against opponents three or more size categories smaller than the dragon. A crush attack affects as many creatures as fit in the dragon's space. Creatures in the affected area must succeed on a Dex save or take bludgeoning damage and become grappled (level 2). Crush attacks deal damage equal to the maximum melee attack the dragon can make. Grappled targets automatically take this damage again at the beginning of their turns for as long as they remain grappled.

Corrupt Water (sp, 1/day) - Once per day this dragon can stagnate 10 cubic feet of still water, making it foul and unable to support water-breathing life. The ability spoils liquids containing water. Liquid-based magic items (such as potions) and items in a creature's possession must succeed on a WIS save or become ruined. This ability is the equivalent of a 1st-level spell. Its range is equal to that of the dragon's frightful presence.

Acid Pool (su, Acid, every 1d4 rounds) - This dragon can use its breath weapon to create an acid pool as a standard action. This acid pool has a radius of 55 feet. When an acid pool is created, anyone inside its area takes 22d6 points of acid damage (Dex halves). Any creature that starts its turn touching this pool takes damage, but can make a Dex save for half. Each round, the total damage dice of the pool is halved (10d6 round 2, 5d6 round 3, 2d6 round 4, 1d6 round 5) until the result would be less than 1d6. The acid pool floats on water, and deals damage to anything on the surface.

Frightful Presence (Free)(ex, Mental, Fear) - As a free action, this creature can demonstrate its frightful presence (usually through a roar or other effect). Opponents who witness this gain level 3 fear for 5d6 rounds. Opponents who succeed on a save are immune to this effect for 24 hours. If the target loses sight of the creature, it gets a new save each round.

Breath Weapon (su, Acid, every 1d4 rounds) - 120-ft. line of acid, 24d6 acid damage

Tail Sweep (ex) - As a standard action, this dragon can sweep multiple targets with its tail. The sweep affects a half-circle with a radius of 30 feet. Creatures within the swept area are affected if they are four or more size categories smaller than the dragon. The sweep deals as much damage to all creatures in range as the tail slap normally does to a single target, though targets can make a Dex save to halve this damage.

Vital Strike (ex) - As a standard action, the Black Dragon (Great Wyrm) can make one attack at full bonus that deals additional damage. Roll the damage from the attack twice before adding other damage bonuses. This extra weapon damage is not multiplied on a critical hit but is still added to the total.

DESCRIPTION

Environment: warm marshes

Organization: None

Treasure: triple

Hissing green acid drips from the fanged maw of this black-scaled, horned dragon.

Lording over the darkest swamps and marshes, black dragons are the undisputed masters of their domain, ruling through cruelty and intimidation. Those who dwell within a black dragon's reach live in fear. Black dragons tend to make their lairs in remote parts of the swamp, preferably in caves at the bottom of dark and fetid pools. Inside, they pile up their filthy treasure and sleep amid the roots and muck. Black dragons prefer their food a bit rotten and will often allow a meal to sit in a pool for days before consuming it. Black dragons prefer treasures that do not rot or decay, making their hoard, full of coins, gemstones, jewelry, and other objects made from stone or metal.
