Hand Crossbow Bolt of Madness

On a successful hit from a hand crossbow, this bolt requires the victim to succeed on a DC 12 Fortitude saving throw or spend the entire next round attacking itself, dealing itself 5 of HP damage. This effect only lasts one round. It must be declared (turned in) before sliding the weapon token. Multiple hits in the same round do not stack, but the monster could be affected in consecutive rounds–assuming it continued to fail the saving throw.

Note: Attacks made with this ammunition deal a total of 0 HP damage–whether the saving throw was successful or not. However, the monster will still damage itself if it fails the saving throw.
