Demon Co-Op When an attack hits a weakness, the allies that share the attacker's alignment follow up with one almighty hit on each target that was hit. Pick up to three allies. Preparedness raises an ally's hit by half. The total is cut to 75% with two allies and to 70% with three. Co-Op does not trigger on a defending enemy.
