You call the Daemon Sultan of the Outer Gods from its throne at the center of existence to your vicinity. Azathoth makes a saving throw (+14 bonus). The save DC gains a +1 bonus for every twenty secondary casters. On a successful save, it ignores this spell, nothing happens, and this doesn’t count as failing to cast the spell as a formula.

On a failed save, Azathoth’s influence manifests at a random location within range accompanied by 1d4 servitors of the Outer Gods and 1d6 – 1 other unspeakable creatures of great power from its court. Until the duration ends, you can overhear profound cosmic truths Azathoth mindlessly touches upon and might glean potent insights at the GM’s discretion. When this spell ends, Azathoth’s influence remains and immediately becomes enraged.

After Azathoth arrives, you can attempt to banish it again as an action as long as you maintain concentration on this spell. Azathoth must make another saving throw.

On a failed save, the influence ends and its retinue departs, and the duration of the spell ends. On a successful save, you must succeed on a Constitution saving throw against this spell to maintain concentration or it ends.

No tome is known to contain this spell, but servitors of the Outer Gods are eager to teach it or force others to perform it, as the spell requires the caster to break Elder Signs, which aids the Outer God’s return. Unless Azathoth is banished quickly, the casting of this spell can easily lead to the utter destruction of the planet to which it is conjured.
