the giant tree boss? if you mean the tree thing with the eye then i know what you're talking about.
to defeat the boss you should defeat his minions first. Try to follow a pattern in where they shoot. then start hacking at the tree's shield bit to his core. knock it out the way and then start hitting the core. when the shield starts moving then it's time to run away. the shockwave should miss you if you run to the side near the other end of the room. watch for where the red circles appear as vines will shoot up and try to hit you. As you battle, the minions will shoot in more annoying places and vines may suddenly appear out of nowhere. stay alert and repeat to say goodbye to the stupid thing.
Sigh, every forum I use turns into a war zone. I kinda miss this place. I might pop in every now and then, but there are so many scars already, I don't feel like I have a home here.
