The Impact Grenade is an explosive that does not have a timer. Instead, it detonates as soon as it comes in contact with a surface. If an enemy is hit directly by the grenade, the results can be deadly. When hit directly, the player will receive a +50 EXP bonus. The Fun Fact Mad Bomber goes well with this Support Item and is almost a flat 30 point add-on. It can be considered an alternate to the Hatchet to those without the best aim.
