The Iron Colossus is a titanic war machine forged from magnetized iron — at 70% HP it activates an enormous electromagnetic field that bends the trajectory of ALL incoming projectiles away from its body! Arrows, bolts, stones, and magical projectiles curve harmlessly around it. Your entire ranged offense is nullified by physics. EMP Cannon units generate a disruptive electromagnetic pulse that overloads the colossus's magnetic generators, collapsing the field and allowing normal attacks. Each EMP disruption earns +56G short-circuit bonus. Deploy EMP Cannons before the Colossus hits 70%!
