A “druid staff” artifact, which can be invoked to create a patch of grass similar in size to a stinking cloud, radius 4-5. Enemies within the grass radius become rooted to the ground, making them unable to move (but still able to fight, shoot, etc) for some time. While wielding it, you can chat with trees, which causes them to give you some food, mana, or rarely a pet (possibly an ent).
