The Black Crow was damaged about 55% health in it's first phase.
Stacked debuff from Uruk's Smelting to 20% - using Leam Slam to reset fully broken armour caused by Resonating Shield.
Used Boneshatter whenever boss got primed for heavy stun. Used Perfect Strike or regular Mace Strike

The door to the area with the bell was open at this point.
The boss could be kited anywhere in the starter area or the bell area.
At this point the boss has become invulnerable / untargettable to player skills. (resonating shield dmg or armour breaking debuff failed to apply, same goes for strike or slam skills).
Player to boss collision still worked - shield rush stopped running, but didn't apply damage.
Boss kept attacking and damaging player.

Area: Blooming Field (all listed content completed : rare and unique monsters defeated, breach )
Monster level: 81
29% increased Experience gain
Players are periodically cursed with Elemental Weakness

Indeed.. the unique/ rare monster kill goal is marked.
