Karsus' Avatar

Karsus's avatar was a very powerful spell which altered the very disposition of reality. The user of this spell could attain the ability to bend reality itself to their whim.

Effect

The caster of this ritual must speak the name of a Deity at the completion of the ritual. Upon speaking the Deity's name, the user binds their divine power and abilities to their whim, effectively switching places with said Deity. This power only lasts for but a few hours, before the Universe cosmically corrects itself and returns both beings to their natural state.

Side/Secondary Effects

The cost of casting this spell has a heavy toll on both the Deity and the caster. Only two recorded occurrences of the Spell's completion have been recorded. The first casting, by the wizard Karsus himself caused the death of a deity, nearly shattering the Winds of Magic forever. The second time was by an unknown caster who had allegedly taken the role of Pelor, the Dawnfather, in order to halt a cosmic event from shattering the Prime Material Plane.

Manifestation

Upon completion of the spell, the last sound heard for a time is the name of the chosen Deity. The spell is so immensely powerful that all nature halts at its casting. Birds, plants, bugs, animals all stop and wait, as if all of reality holds its breath, waiting and watching.

Source

The spell is so incredibly complex that it requires several powerful components just to ready the ritual. The caster must possess the heart of a fully-grown Gold Dragon, Blood of a Kraken, an Item of Divine Make, and the feathers of a Solar's Wings. Once the items have been prepared, the caster must begin the six-hour long ritual to complete the spell.

Discovery

The Wizard Karsus first discovered the spell after spending nearly fifty years researching its means. Karsus had access to an endless array of tools and reagents that he was able to cast the spell himself. The results were catastrophic, Karsus attempted to become the Avatar of Mystra, and upon doing so he immediately killed her. With Mystra's death, the Winds of Magic simply stopped flowing. The Silver Tower went dormant, and the Veil collapsed. This is one of the only recorded moments that deities of the Prime Pantheon intervened themselves. The gods Pelor and Serenrae descended to Korrisia and worked to draw Mystra's broken power together and recreate her. Mystra's form was never fully recovered, and the Knowing Mistress Ioun was born from her corpse.
