A 16 Hit Dice elemental (see B/X Essentials: Monsters) is summoned from an elemental plane of the caster's choice (air, earth, fire, water) to do his or her bidding.
A large volume of the appropriate element is required for the summons to work.
Commanding an elemental requires great concentration: the caster may not take part in combat, cast other spells, or move at greater than half speed.
While control over the elemental is maintained, the caster may dismiss it at any time, sending it back to its plane of origin.
If the caster's concentration is disturbed, the spell's command of the elemental ends. It is, henceforth, a free-willed entity and will immediately try to kill the caster and any who get in its way.
A conjured elemental may be dispelled by dispel magic or dispel evil.
The caster may summon at most one elemental from each plane in a single day.
