Sneak Attack (Ex): Whenever a target is denied its Dexterity bonus to AC or when the shadovig flanks the target, the shadovig deals an additional 1d6 damage. This ability works exactly as the rogue's sneak attack ability.

Poison (Ex): Claws, Fortitude save (DC 17); initial damage 1 Strength drain*. Secondary damage 2d6 Strength. *The initial damage of shadow essence poison is permanent; the secondary damage is temporary.

Spell-like Abilities: 3/day - invisibility, mirror image. These abilities are as the spells cast by a 4th-level sorcerer.

Shade Abilities (Su): In darkness. the shadovig gains a + 10 foot increase to its speed, a +4 deflection bonus to Armor Class, a +2 competence bonus to attack and damage, a +4 luck bonus on all its saving throws, a +2 increase in its Constitution and Charisma scores, a +4 racial bonus to Listen and Spot checks. and a +8 racial bonus to Hide and Move Silently checks.

Uncanny Dodge (Ex): Shadovig react to danger before their senses would normally allow them to do so. They retain their Dexterity bonus to AC (if any) regardless of being caught flatfooted or struck by an invisible attack. They still lose their Dexterity bonus to AC if immobilized.

Skills: Shadovig use their Dexterity for Climb and Jump checks. They receive a +2 racial bonus to Search, Spot, and Listen checks in addition to any additional bonuses they receive in darkness.

Shadovig prefer to avoid a direct fight, relying instead on the shadows to give them the ability sneak up on a target or make wicked use of their poisoned claws.
