Grenado

When used to make a successful missile attack (slid as weapon on the combat board), this alchemical weapon deals Blunt damage to the monster. It is usable only once, whether the attack succeeds or misses.

Like all alchemical weapons, this item deals double damage if the attacker scores a natural 20 on the attack slide. But unlike thrown physical weapons (dagger, spear, etc.), alchemical weapon damage is not increased by the attacker’s Strength score.
