The Porcupine Bomb deals damage on impact and launches numerous spikes outwards. Each spike inflicts poison upon enemies. Every shot consumes a low amount of mana and the weapon can be thrown quickly. It is great for taking out groups of enemies and can handle flying enemies better than the Firestorm Grenade because of the shrapnel. The secondary fire throws three grenades in a random pattern at a higher mana cost and slower fire rate.
The initial blast can harm the player, but the spikes cannot.
