Bob-omb

Throw Me! A Bob-omb can be thrown as a ranged weapon attack (+ 4 to hit). If it hits, it does 12 (4d6) fire damage, and if it misses, it deals 3 (1d6) fire damage due to the blast radius (not including natural 1s on attack rolls).

Walk. After 3 turns in battle, a Bob-omb will walk around for 3 rounds. Assuming nothing detonated it yet, the Bob-omb stops and flashes orange for one turn (this is your cue to run for it). After flashing orange, the Bob-omb explodes, dealing 12 (4d6) fire damage to anyone within 10 feet of it. It kills itself in the explosion.

Explode. After hitting a target when thrown, or after touching a creature while it (the Bob-omb) is walking, it explodes, dealing 12 (4d6) fire damage. If a thrown Bob-omb attack misses but is not a natural 1 on the attack roll, it instead deals 3 (1d6) fire damage to the targeted creature. It kills itself in the explosion. Reducing a Bob-omb to 0 Hit Points also makes it explode.
