Description

Components V, S, F/DF (a tiny bag and a small candle)
Saving Throw none; Spell Resistance no   DESCRIPTION   This spell summons an extraplanar creature (typically an outsider, elemental, or magical beast native to another plane). It appears where you designate and acts immediately, on your turn. It attacks your opponents to the best of its ability. If you can communicate with the creature, you can direct it not to attack, to attack particular enemies, or to perform other actions. The spell conjures one of the creatures from the 1st Level list on Table: Summon Monster. You choose which kind of creature to summon, and you can choose a different one each time you cast the spell.   A summoned monster cannot summon or otherwise conjure another creature, nor can it use any teleportation or planar travel abilities. Creatures cannot be summoned into an environment that cannot support them. Creatures summoned using this spell cannot use spells or spell-like abilities that duplicate spells with expensive material components (such as wish).   When you use a summoning spell to summon a creature with an alignment or elemental subtype, it is a spell of that type. Creatures on Table: Summon Monster marked with an “*” are summoned with the celestial template, if you are good, and the fiendish template, if you are evil. If you are neutral, you may choose which template to apply to the creature. Creatures marked with an “*” always have an alignment that matches yours, regardless of their usual alignment. Summoning these creatures makes the summoning spell’s type match your alignment.   The summon monster spells have numerous entries representing creatures that are summoned from the Outer Planes, and thus have the celestial or fiendish template or can be summoned with the entropic or resolute template (Pathfinder RPG Bestiary 2, pages 292 and 293, respectively).
