A Cube with silver trim and a blackened wood body, part of which is pushed out, is pushed back into place, releasing a blast of dark energy. Anyone in a 30 ft cone in front of the user must make a CON Saving Throw (DC 14) and take 8d12 of force damage. On a success, they take half damage. On a fail, they take full damage and are knocked prone AND deafened for 3 turns. After using this item, the user rolls a percentile die. If they roll a 20or lower, they are hit by the blast. If they fail the percentile roll 5 times, the cube explodes, destroying the item and Gravely Injuring the user. The user is knocked unconscious with 2 death throws failed. They can't be healed until they do all their death saves. If they succeed in 3 saves in a row, they get back up with the item still broken. If they fail one death save, they die, with only high-level magic being able to bring them back.
