This greataxe is made from obsidian, but is as strong as adamantine. Dripping acid constantly, being hit by this weapon also causes acid burn damage. Striking a living tree heals the wielder while killing the tree.
Treerazer loans the weapon to his minions on occasion. However, he can use the wielder's senses, know where the wielder is at all times, use his spell-like abilities through Blackaxe, and recall Blackaxe regardless of distance.
