Conjure Earth Elemental (wizard)

When a wizard casts Conjure Earth Elemental, he summons forth an earth elemental and compels it to do his bidding.

In-game description
"Conjure Earth Elemental Upon casting a Conjure Earth Elemental spell, the caster opens a special gate to the Elemental Plane of Earth and an earth elemental is summoned in the vicinity of the caster.There is a 60% chance that a 12-Hit Dice elemental appears, a 35% chance that a 16-Hit Dice greater elemental appears, and a 5% chance that a 24-Hit Dice elder elemental appears. The elemental will do the bidding of the caster until it is slain or the duration of the spell runs out. All of the commands given to the elemental are done telepathically, so there is no time lost due to miscommunication and no need to know the language of the summoned creature. The elemental is locked into a psychic contest with the caster for 3 rounds after being summoned. At the end of this time, if the caster has won, he has control of the elemental, however, if he has lost, the elemental goes berserk and tries to kill him. However, every time this spell is cast, there is a 15% chance that the elemental will escape the instructions of the caster, go berserk, and attack the wizard who dared summon it. If it can't reach the summoner, it will fight its way toward him. This berserking elemental will also remain until slain or the spell's duration expires. This does not prevent the use of other charm-type spells after the contest was lost. If charm spells are used before the contest is over, they will have no effect on the outcome."
