Earth Staff

Description
There are five common types of earth staves.
 * The first type, is a long solid piece of crystal.
 * The second type, introduced in the Thursday March 9th update bears a strong resemblance to the Earth Wand, with a crystal head and a black shaft.
 * The third type, mainly found in Cantha and the Charr Homeland, is metallic with a flat hexagonal head which appears to have a fossil embedded in it.
 * The fourth type is somewhat rarer, and is referred to by some players as an 'Obsidian Earth Staff' or 'Orrian Earth Staff'. It is a long and thin staff with yellow spiral patterns on it, with an obsidian stone attached to the bottom, and one floating on the head with a constant faint glow.
 * The fifth type is normally referred to as the Elonian Earth Staff, as it is commonly found in Elona, and features a small stone head on the end of the staff, with a larger stone hovering above and surrounded by pebbles (despite its look, the staff head is not animated).

The obsidian version of this item can be found in some advanced areas like the Fissure of Woe, Southern Shiverpeaks, Realm of Torment, Ring of Fire Islands, and reward chests from GW:EN Dungeon Crawls. But, it has also been known to drop from undead in Kryta, and in places in and around Ascalon (Pre-Searing Ascalon and Post-Searing). It has also been reported to drop in explorable areas of Kaineng City in Cantha and in the Crystal Desert of Tyria.
