jade bomb

The swollen siege piece of the bomb family, closer to a demolition charge than an ordinary hand bomb. Its fuse stretches to 4 seconds, and the detonation expands to a 10-block blast that can peak at 30 damage.

That longer warning changes how it is used. Throw it early, let it settle in a doorway or pit, and give the room time to accept what is coming; in a panic it feels cumbersome, but for breaching or clearing clustered threats it is the brutal end of the bomb line.
