Caelli-Merced Ice Detonator

The Caelli-Merced Ice Spike is a specialty explosive made popular by the fishermen of Neftali. The fist-sized explosive is bottom heavy: Fishermen drill a hole into the ice (approximately half a meter deep) and then drop the ice spike, bottom first into the shaft. While the timer counts down, the fishermen rush to get beyond the eight-meter blast radius of the explosive.
