When used to make a successful missile attack (slid as weapon on the combat board), this alchemical weapon deals Sonic damage to the monster. Though it is not stated on earlier versions of the token, the thrower need only hit AC 15 or higher. There is no saving throw to mitigate damage. It is usable only once, whether the attack succeeds or misses.
The damage from this item is doubled* if the victim is a Construct or a crystalline creature.
