Colossus

Restores HP equal to 1000% of Colossus' ATK to 2 friendly Heroes and creates a shield that lasts for 5s around each of these targets. When this shield is in play, Colossus takes 50% of damage (amount before DMG Reduction effects) on behalf of the shielded target. (Cooldown: 8s. When this Hero has less than 70% of his HP, he cannot receive more than 50,000 DMG per hit and becomes immune to Stun, Silence, and conditions from Calamity.)
