Index of Spells by Level - Exalted Arcanist 6

Positive energy ray deals extra damage to evil outsiders and undead.

You must succeed on a ranged touch attack with the ray to strike a target. A creature struck takes varying damage, depending on its nature or its home plane of existence and your level:

As lesser planar ally, but up to 12 HD.

By casting this spell, you request your deity to send you an elemental or outsider (of 12 HD or less) of the deitys choice or two creatures of the same kind whose Hit Dice total no more than 12. If you serve no particular deity, the spell is a general plea answered by a creature sharing your philosophical alignment. If you know an individual creatures name, you may request that individual by speaking the name during the spell (though you might get a different creature anyway).

You may ask the creatures to perform one task in exchange for a payment from you. Tasks might range from the simple to the complex. You must be able to communicate with the creatures called in order to bargain for their services.

The creatures called require a payment for their services. This payment can take a variety of forms, from donating gold or magic items to an allied temple, to a gift given directly to the creature, to some other action on your part that matches the creatures' alignment and goals. Regardless, this payment must be made before the creatures agrees to perform any services. The bargaining takes at least 1 round, so any actions by the creature begin in the round after it arrives.

A task taking up to 1 minute per caster level requires a payment of 100 gp per HD of the creature called. For a task taking up to 1 hour per caster level, the creature requires a payment of 500 gp per HD. A long-term task, one requiring up to one day per caster level, requires a payment of 1,000 gp per HD.

A nonhazardous task requires only half the indicated payment, while an especially hazardous task might require a greater gift. Few if any creatures will accept a task that seems suicidal (remember, a called creature actually dies when it is killed, unlike a summoned creature). However, if the task is strongly aligned with the creatures' ethos, it may halve or even waive the payment.

At the end of its task, or when the duration bargained for expires, the creature returns to its home plane (after reporting back to you, if appropriate and possible).

Note: When you use a calling spell that calls an air, chaotic, earth, evil, fire, good, lawful, or water creature, it is a spell of that type.
