Quivering palm

From NWNWiki

Type of feat: class
Prerequisite: monk 15

Specifics: This ability may be used once per day to instantly kill an opponent. If the character makes a successful attack after activating the ability, the target must make a fortitude save (DC 10 + half the monk's level + the monk's wisdom modifier) or die.

Use: selected. Quivering palm may only be used on creatures at a lower level than the character. Creatures of the construct and undead types are immune to this effect, as are any creatures that are immune to critical hits.
