Corruptoray: It fires a beam of corruption, which gives towers that are being hit by it to have a 5% chance of attacking a nearby tower. It deals 0.05 damage a second. Sheer Darkness: It removes as much light as it can, cutting the range of towers down to 15% of the normal amount. Super Monkeys are unaffected, and High Energy Beacons and Ray of Dooms light up a decent-sized area.
