Spore Crawlers are stationary anti-air defensive units and similar to the Spine Crawler they will slowly die if not standing on Creep. They have extremely long range, are capable of quickly destroying any Crap Patrolair units but they cannot target the Battlecruiser support, Mohandar, Dusk Wing and Carrier. Hybrid Dominators and spores are a lethal combo as the hybrid will Void Prison you up into the air and the many spores inside of the 20 range radius will all shoot you. Their damage versus heroes is heavily reduced but in the wrong area it is certain death.
