Summon monster IX

Summon monster IX was the most powerful of a series of summon monster spells that called an outsider to fight for the caster.

Effect
This spell functioned just as all summon monster spells. It could summon a couatl, leonal, or celestial roc from one of the celestial planes; an elder elemental from one of the Inner Planes; a green slaad from the plane of Limbo; or a hamatula, fiendish dire shark, gargantuan fiendish monstrous scorpion, night hag, bebilith, colossal fiendish monstrous spider, or hezrou from one of the fiendish planes. It could also summon a monadic deva, firre, moon dog, quesar, sword archon, or ursinal from the Upper Planes or a farastu or Wastrilith from the Lower Planes.

Alternatively, it could summon one to three celestial dire bears, celestial cachalot whales, celestial triceratops, or lillends from the Upper Planes; one to three greater elementals from the Inner Planes; one to three blue slaadi from Limbo; or the same number of fiendish giant squids, hellcats, colossal fiendish monstrous centipedes, fiendish dire tigers, gargantuan fiendish monstrous spiders, fiendish tyrannosaurus, or vrocks from the Lower Planes. Moreover, it could summon one to three hollyphants, lupinals, maelephants, or warden archons.

Finally, it could summon from two to five creatures that weaker summon monster spells could conjure.

Multiple creatures summoned had to be within 30 feet of each other.
