In-game description
"Staff of Earth Linked to the Plane of Earth, this staff may have been fashioned by an ancient druidic sect. It can summon an Earth Elemental, though it also has the potential to slay such creatures in a single blow, possibly hinting at how difficult it is to control them.  It can also free a person from the earth by casting Stone to Flesh. Some abilities are limited by charges."
