* Keldovan the Harrier
Keldovan is the first CoA boss players will meet who has received a large boost to not only his Melee, but also both Direct and DoT AE damage. This fight serves as an example of how important Rampage Tanks will be inside the CoA. Healers and DPS toons will not appreciate landing in his target area for this mechanic in this zone. He also boasts the first of many significant Hitpoint increases that will test the reserves of raids who come unprepared for endurance fights that can outlast a raid wide burn.
Keldovan's adds have received their own statistical boosts and will require teamwork to prevent them from overwhelming the raid while efficiently triggering Keldovan's de-powering mechanic.
Strategic Tip: Killing several of Keldovan's adds fully strips away his powered up forms and leave him in a less dangerous state. However, he will also do periodic checks on his adds and will begin to regain his powers if he finds that all four of them are alive.
