Ulcerated Tree Spirit Boss Strategy and Attack Patterns
Avoid Its Front and Attack from the Sides
For thie Ulcerated Tree Spirit, it's effective to avoid its front and attack from its sides instead. If you can dodge its arm swings and tail attacks, you can land hits while minimizing damage taken.
Beware of its AoE Attack Below 60% HP
When its HP drops below 60%, it will trigger an AoE Explosion, attacking the surrounding area. After this, be aware that all its attacks will be imbued with Holy Affinity damage, so you will take damage even with a 100% damage negation shield.
How to Dodge Attacks
| 1 | Dodge to the Side Once It Charge Attacks After Roaring |
|---|---|
| 2 | For the Tail Spin Attack, dodge forward if attacking, backward if defending |
Dodge to the Side Once It Charge Attacks After Roaring
After it roars, the charging bite attack is unblockable. It always prepares for a run-up after the roar, so the moment you see it charge, dodge to either the left or right. Using evasion Weapon Skills like "Raptor of the Mists" or "Bloodhound's Step" is also effective for staying safe.
For the Tail Spin Attack, Dodge Forward or Backward
If it thrusts its tail forward, it's a sign of a tail spin attack. Dodging sideways might get you caught and take damage, so dodge forward or backward.
