Prerequisite: Requires 3 levels of Rogue.
Once per long rest, if a rogue studies his victim for 3 rounds and then makes a sneak attack with a melee weapon that successfully deals damage, the sneak attack has the additional effect of possibly either paralyzing or killing the target. The death attack fails if the target detects the rogue or recognizes him as an enemy. If the victim of such a death attack fails a Constitution saving throw (DC 10 + the class level + the Intelligence modifier) against the kill effect, she dies. If the saving throw fails against the paralysis effect, the victim is rendered helpless and unable to act for 1d6 rounds. If the victim’s saving throw succeeds, the attack is just a normal sneak attack.
