False Death

You can cause your victims to appear dead while actually remaining alive.

Prerequisite(s): Int 13, true death class feature

Benefit: When you successfully make a death attack against a creature and choose to paralyze it, the creature remains helpless for a number of hours equal to your assassin level. During this time, they appear dead and cannot take any actions, though they are still able to perceive their immediate surroundings. A creature that studies the victim for a full minute and makes a successful Perception check (DC 20 + your assassin level + your Intelligence modifier) is able to determine that the victim is paralyzed but not dead.
