Anyone know if the Lethal Grace damage from the vigilante is multiplied on a critical?
Multiplying Damage: Sometimes you multiply damage by some factor, such as on a critical hit. Roll the damage (with all modifiers) multiple times and total the results.
Note: When you multiply damage more than once, each multiplier works off the original, unmultiplied damage. So if you are asked to double the damage twice, the end result is three times the normal damage.
Exception: Extra damage dice over and above a weapon's normal damage are never multiplied.
It isn't extra damage dice, and there is no exclusionary text, so yes it is multiplied on a crit.
Oh snazzy. Thanks!
