Nutcracker (boss)

LocationInstanced encounter
WeaknessMechanical complexity over raw DPS
DropsChance at the Nutcracker Deviant
Recommended Level
MovesDamage windows only open briefly between major mechanics

Tip: Can be soloed or fought with up to 4 players — each additional player raises the boss's HP, so more isn't always easier.

Treant

LocationGaia Cliff Monolith (Manibus scenario) or Avalanche Monolith (Way of Winter scenario)
WeaknessThe woman's body located near its head/top-front
DropsStandard boss-tier rewards
Recommended Level
MovesImmune to direct attacks until 3 surrounding Vines are destroyed at their glowing red weak spots

Tip: Do not shoot the Treant itself first -- it is immune and will simply aggro. Destroy all 3 Vines from a safe vantage point using their weak spots, then shift fire to the actual weak point near its head.
