Lesser planar binding is a conjuration spell that traps an outsider until it performs a task.


Casting this spell attempts a dangerous act: to lure a creature from another plane to a specifically prepared trap, which must lie within the spell's range. The called creature is held in the trap until it agrees to perform one service in return for its freedom.

To create the trap, you must use a magic circle spell, focused inward. The type of creature to be bound must be known and stated. If it has a specific, proper, or given name, this must be used in casting the spell.

The target creature must attempt a Will saving throw. If the saving throw succeeds, the creature resists the spell. If the saving throw fails, the creature is immediately drawn to the trap (spell resistance does not keep the creature from being called). The creature can escape from the trap with a successful SR roll, dimensional travel, or a successful Charisma check (DC 15 + 1/2 its level + its Charisma modifier). It can try each method once per day. If it breaks loose, it can flee or attack you. A dimensional anchor cast on the creature prevents its escape via dimensional travel. You can also employ a calling diagram (see "Calling," page 157 of the Player's Handbook) to make the trap more secure.

If the creature does not break free of the trap, you can keep it bound for as long as you dare. You can attempt to compel the creature to perform a service by describing the service and perhaps offering some sort of reward. You make a Charisma check opposed by the creature’s Charisma check. The DM then assigns a bonus based on the service and reward, from 0 to +6. This bonus applies to your Charisma check. If the creature wins the opposed check, it refuses service. New offers, bribes, and the like can be made or the old ones re-offered every 24 hours. This can be repeated until the creature promises to serve, until it breaks free, or until you decide to get rid of it by means of some other spell. Impossible demands or unreasonable commands are never agreed to. If you roll a 1 on the Charisma check, the creature breaks free of the binding and can escape or attack you.

Once the requested service is completed, the creature need only so inform you to be instantly sent back whence it came. The creature might later seek revenge. If you assign some open-ended task that the creature cannot complete though its own actions (such as "Wait here" or "Defend this area against attack"), the spell remains in effect for a maximum of 1 day per caster level, and the creature gains an immediate chance to break free. Note that a clever recipient can subvert some instructions.

Descriptor NoteEdit

When you use a calling spell to call an air, chaotic, earth, evil, fire, good, lawful, or water creature, it is a spell of that type. For example, lesser planar binding is a water spell when you cast it to call a water elemental.
