Prickly

Prickly
This mutation grows three large spikes from the player's torso, enabling a close-range attack which deals heavy damage to up to three nearby enemies. Passively, Prickly also deals damage to any enemy that lands a hit on the player, but only when the spikes are fully recharged. With its generous damage and quick recharge, it is one of the most valuable Exo Mutations. It can make short work of most any weak mutant, and is extremely useful in many loadouts.

Burst
Prickly can be upgraded to Prickly Burst, which extends the range of the primary attack by launching the spikes from the player's body rather than simply poking. While it can no longer break objects within melee range, it can deal essentially instant damage to up to three enemies nearby without needing to aim, making it an incredibly useful ranged Exo Mutation.

Plus
Prickly can also be upgraded to Prickly Plus, doubling the number of spikes and the range of the attack.
