Mad Angel
Auto-retaliate should be disabled or you risk being dragged during the blast attack, which can result in failing the mechanic.
The Mad Angel attacks primarily with melee, and is weak to golembane weapons.
Protect from Melee will reduce the max hit of its standard attacks from 31 to 5. After three standard attacks, it will perform a special attack.
Upon reaching 350 Hitpoints (~45%), the Mad Angel will enter the enrage phase at the next available opportunity, denoted by a overhead message. During this phase, its special attacks are performed quicker, requiring quicker reaction times to counter them. Additionally, it will use all three of its specials consecutively at the start of this phase.
Since the blast attack damage mechanic always deals a fixed 18-22 damage, players with high damage setups can intentionally fail this mechanic for the next sweep/smite attack punish to occur sooner.
