At 20th level, the slayer becomes a master at capturing or killing his studied targets. As a standard action, he can make a single attack against a studied target at his full attack bonus, choosing one of the following effects: kill, knock unconscious for 1d4 hours, or paralyze for 2d6 rounds. If the attack succeeds, the target takes damage normally and must succeed at a Fortitude saving throw or suffer the additional effect. The DC of this save is 10 + 1/2 the slayer's level + the slayer's Intelligence modifier. Whether or not the target succeeds, it cannot be targeted by this ability again (by any slayer) for 24 hours.
