Summon Monster V

Spell Effect
This spell - of which there are nine levels, I to IX - summons an extraplanar creature, typically an Outsider or Magical Beast native to another plane or an Animal whose Challenge Rating falls into the limits described below and apply either the Celestial, Entropic, Fiendish, or Resolute template to the creature(s). In order to summon a creature, you must have successfully added the creature to your personal list at some point prior to casting the spell, which requires you to have encountered or learned about the creature and succeed at a Knowledge (Planes) check about the creature, typically with a DC of 15 + creature’s CR, in order to properly identify the exact details of how to summon the creature. Some creatures may have a higher or lower DC, and the GM may rule that some creatures cannot be summoned through summon monster.

The summoned creature 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 such creature whose Challenge Rating falls within the range given for the level of summon monster spell cast, or multiple creatures of lower Challenge Ratings, as indicated in the table below. You choose which kind of creature to summon, and you can choose a different one each time you cast the spell.

When you use a summoning spell to summon a creature with an alignment or elemental subtype, it is a spell of that type. Animals summoned with summon monster are summoned with the Celestial template if you are good, the Entropic template if you are chaotic, the Fiendish template if you are evil, and the Resolute template if you are lawful. If you are neutral or have multiple templates that could apply, you may choose which template to apply to the creature. Such creatures always have an alignment that matches yours, regardless of their usual alignment. Summoning these creatures makes the summoning spell's type match your alignment.
