Devastation turrets deal heavy damage to armored enemies and make a good compliment to perdition turrets, which deal bonus damage to light enemies. When upgraded, devastation turrets slow enemies, making them excellent for base defense.
Devastation turrets are renamed "Blaster Billy" when Swann reaches Level 3. The turrets can slow enemy units similar to the Concussive Shell ability of marauders.
