It’s not a nice fight, is it?
But if you’re intent on besting it in single combat, you’ve come to the right place.
It makes your previous trek down the Fringefolk Hero’s Grave to reach this boss look positively simple.

Below I’ll walk you through how to defeat the Ulcerated Tree Spirit.
Don’t fall for it.
I’d strongly advise you not waste your time attempting to fell this boss at an early level.

Get ready to dodge.
The thing to watch out for is when the boss shakes its head rapidly from side to side.
Instead, it utilises single heavy attacks, relying on its strange movements to catch you off-guard.

This means you rarely have to worry about quick follow-up attacks with this boss.
So don’t get greedy.
