If he hears a bell ring, Tumbo bites a nearby metal lead or (if one is not available) an adjacent creature at the beginning of his turn, if possible.

HP 18; Immunities bleed, electricity, paralyzed, poison, sleep

Speed 5 feet, fly 50 feet

The spark bat transforms into lightning that arcs to a large piece of metal within 100 feet, such as a suit of metal armor or a metal weapon. The bat then returns to its normal form in a space adjacent to the metal. This movement doesn't trigger reactions.
