A natural disaster of catastrophic proportions springs forth from a point you can see and rapidly spreads to cover up to a 10-mile radius. Upon casting this spell, the caster can duplicate any or all of the most extreme effects of Earthquake, Fimbulwinter, Fire Storm, Ice Storm, Meteor Swarm, Whirlwind, or any other similar evocation spell so long as the appropriate material component is used in the casting of this spell. Any damage duplicated by this spell is done at its maximum, and the effects last for this spell's full duration. Any creature within range of this spell when it is cast, that enters the spell’s range for the first time on its turn, or if the creature ends its turn there immediately takes damage.
Completing the Pinnacle Evocation Ritual inflicts devastating effects on the caster's psyche. The caster is afflicted with short-term madness for 1d10 x 2 days and must make a DC 20 Wisdom Saving throw. On a failure, they are also afflicted with long-term madness for 1d10 x 10 days. Roll on the "short-term madness" and "long term madness" tables to determine these effects.
