Bouncy Bomb

A normal bomb settles roughly where you threw it. This one does not. It kicks off floors and walls with real force and then keeps rolling along level ground without bleeding off speed, so the crater appears wherever it finally ran out of room rather than where you were aiming.

For digging it is a liability. Drop one into a shaft and it will come back up at you. Where it earns the slot is any time you want the blast delivered around a corner or sent a long way down a flat corridor, and in fights against other players, where nobody can predict the path it will take. Including you.
