Ninja Poison

Type: Monk poisoning enhancement

Prerequisites:
 * Monk level 3
 * Path of Inevitable Dominion
 * 2 Action Points spent on Poisoned Soul enhancement in Ninja Spy tree or
 * 2 Action Points in Sting of the Ninja enhancement (with 10 Action Points spent in Ninja Spy tree) or
 * 1 Action Point in Poisoned Darts core ability (20 Action Points spent in tree, Monk level 12, requires Shadow Veil core ability)

Magical Poison: Target takes 1d4 points of Poison damage every 3 seconds for 15 seconds. The target's vulnerability to poison is increased by 5%. This ability can stack up to 20 times. On timer expiration, 5 stacks of Ninja Poison are removed at a time.

Ninja Poison is a damage-over-time effect and is one of handful of player based poison attacks available to characters that aren't included on a weapon or as a spell.

Ninja Poison is injected on a critical hit with Sting of the Ninja, on a failed saving throw with the Poisoned Soul Ninjutsu enhancement (as part of a Touch of Despair finishing move) or from Poisoned Darts, a Level 12 Ninja Spy core ability.

Except when using Poisoned Darts, Ninja Poison can only be injected using an actual piercing or slashing weapon such as shortswords, kamas or shuriken. Special effects on handwraps or items or feats that note piercing or slashing damage, such the Brawling Gloves, Ivy Wraps or Vorpal Strikes do not qualify as a piercing or slashing weapon; Ninja Poison cannot be injected by melee while unarmed. Sting of the Ninja, which applies Ninja Poison on critical hits from shuriken, cannot inject poison using any kind of bow, even if Zen Archery is used.

Ninja Poison's vulnerability effect increases the effect of untyped poisons found on weapons, other enhancements or items such as the Envenomed Blade, the Venomed Blades enhancement from the Drow racial tree or Rogue Assassin enhancements or the Quiver of Poison. The vulnerability appears to scale as well, from 5% with 1 stack, up to 20 stacks or 100% vulnerability to poison.

As a magical poison, Ninja Poison is effective on any enemy that is not immune to poison, including Named Monsters.

Ninja Poison's damage ticks once every 3 seconds, with up to 20 stacks possible. The poison can be also be forcibly purged at 1d20 damage per stack of Ninja Poison using the Poison Exploit Ninjitsu enhancement. Poison Exploit is magnified in damage using the Deadly Exploits enhancement to 1d30/1d40/1d50 damage per Ninja Poison stack removed (up to 20d50 damage, or 1,000 points of damage).

Ninja Poison, in itself, uses no ki to utilize except by Poisoned Darts (15 Ki, cooldown of 15 seconds).
