Blazing Cataclysm

"[Blazing Cataclysm]."

A furious roar of flames erupted from Selene with her being in the center of it all as the spell spiraled outwards in all directions in a vortex of crimson and gold. Selene's eyes shone like embers with her body engulfed in a blinding pillar of fire. She became a living inferno and her form was slowly hardening into a strange cocoon of molten rock, effectively sealing her inside a fiery shell. As the blazing cocoon formed around her, its surface cracked and oozed with molten lava, radiating an unbearable heat that turned the ground to ash. 

It was the spell itself protecting the caster from what was to come next.

The explosion.
