Domain Expansion: Leviathan's Maw

Description:

The spell can be used to summon Eldritch Blast and the summoning of sigils anywhere within sight as an action that can do 2d8 damage for a damage type of the caster's choice, requiring a Consitution Saving throw with a DC of 15 to hit. The caster can use the sigils to Banish or Restrain a creature, requiring a Strength saving throw with a DC of 18. You can also summon tentacles that can attack any target of the caster's choice. IF the caster is at the 20th level, the caster is able to summon a World Eating Snake, at the cost of their life. This serpent isn't a snake, instead, it is an impossibly large, incomprehensible creature. The Creature: (Click on the link for the image.) This creature REQUIRES a Wisdom, Constitution, and Dexterity Saving throw to cast, with a DC of 20. Failing any of these saving throws will result in the caster being removed from existence by the Goddess of Magic, as this part of the spell is considered a 10th Level Spell. Successfully casting this spell will result in all targets dying instantly, including the caster and their allies. The planet will not be destroyed, however, 100 Miles within the area of casting will have a Successful Power Word: Kill in effect, meaning anything within 100 Miles of the caster including the caster is dead.

Casting Requirements:

Caster must have permission from the Goddess of Magic to cast the spell at Full Power - Caster must know Primordial, Celestial, Abyssal, Deep Speech, Infernal, and Void Speech. Not knowing one of these languages will result in the spell failing. - Caster must be at the 20th Level to cast the spell at Full Power. - Please be advised, this spell is so rediculassly overpowered, I can't classify this as 9th level at the full power version of it, Use of this spell without the DM's approval will result in your character retroactively ceasing existence, regardless to passing the Spell Checks.

How to Cast:

The caster must say the following phrase for the Full Power version of the spell: "Where stars fade to die, where angels cannot hear a single cry, This creature's hunger is pure and raw. Domain Expansion: Leviathan's Maw" in all languages. 

Ubi stellae marces**** mori, Quo angeli clamorem audiunt unum, Haec est pura fames et rudis creatura. Domain Expansion: Leviathan Maw
