Thunderstone

When used to make a successful missile attack (slid as weapon on the combat board), this alchemical weapon deals 8 Sonic damage to the monster. Though it is not stated on 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.

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.

There are two versions of this token. The “woody” version (Thunderstone, one word) deals 8—or 16, see above—damage but the “chippy” version (Thunder Stone, two words) deals damage as indicated by the token’s damage wheel.

Note: This item creates a very loud thunderclap when used which may also be useful in non-combat situations.

*Special Note: Under normal circumstances, Constructs cannot be critically hit. If the person throwing a Thunderstone at a Construct is wearing an item that allows them to crit a Construct and then scores a critical hit, the damage gets tripled–not quadrupled.
