Combat

Although less capable mentally than the average human, lifeleech otyughs possess a cruel cunning that serves them well in combat situations. Knowing that their ability to absorb healing magic takes many by surprise, lifeleech otyughs often seek to wound divine spellcasters early in an encounter.

Constrict (Ex): A lifeleech otyugh deals automatic tentacle damage with a successful grapple check.

Spell-Strengthened Hide (Su): The sickly gray skin of a lifeleech otyugh has been infused with magical energy. This strange energy grants a lifeleech otyugh a +4 deflection bonus to its Armor Class.

Lifeleech Aura (Su): Whenever a spell or spell-like ability with the healing descriptor is used on a creature within 60 feet of a lifeleech otyugh, the otyugh gains the benefit of the healing spell as if it had been one of the spell's targets If a healing spell cast within 60 feet of a lifeleech otyugh would grant it enough hit points to exceed its full normal total, it gains the remaining hit points as temporary hit points. A lifeleech otyugh can't have more temporary hit points from its lifeleech aura than its full normal hit point total. Temporary hit points gained in this manner last for 1 hour.

This ability affects spell completion and spell trigger items (such as scrolls, staffs, and wands), but not other magic items.

Improved Grab (Ex): To use this ability, a lifeleech otyugh must hit with its tentacle attack. It can then attempt to start a grapple as a free action without provoking attacks of opportunity. If it gets a hold, the lifeleech otyugh can constrict.

Skills: A lifeleech otyugh has a +8 racial bonus on Climb checks and can always choose to take loon Climb checks, even if rushed or threatened. *A lifeleech otyugh gains a +8 racial bonus on Hide checks when in its lair, due to its natural coloration.
