Gambler's Grenade

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

If the thrower hits and gets a natural 15 on the attack, both the intended target and the thrower take damage–including all applicable bonuses the thrower would normally be entitled to. However, the thrower cannot be reduced below 1 HP by this item. The intended target can be reduced below 0 HP by this item.

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.
