The new grenade launcher, replacement of Tripbombs. It can launch 2 types of grenades. One is sonic, the other one is phosphorus. Sonic grenades have a random chance to disable the attack of an enemy (Any ranged attack) and make them flee. However, they won't fear to hit you in melee if you get close. Phosphorus grenades have a huge radius and will deal damage over time.
