The Treant is the fifth boss in Resurrection.
The Treant is a mass of wood, animated by magic. His weak point is his eye. The grapple ability must be used to make the way up to the top, where they can fly into it. He will then fall, and be temporarily vulnerable. He can use his axe to attack, jump, throw his axe, which then acts as a boomerang, and shoot out vines. Later in the battle, he can shoot wooden bullets, and throw Storm Skeletons. He has 2000 HP, and his theme is Followers of Darkness -The Second-. He is actually a near duplicate of the Key Guardian.
