Feat: Rejoice in Solstice Storm

Frequency once per hour

You hold your arms out, and the fury of the seasons comes to your jubilant embrace. A storm spirals out from you, dealing 5d8 damage (see below) to each creature in a 30-foot type:emanation, with a Basic Reflex save against your class DC. At 10th level and every 2 levels thereafter, the damage increases by 1d8.

The emanation is quartered into four non-overlapping cones, each of a different season, which must be arranged clockwise from spring, to summer, to fall, to winter. Each cone has different traits, damage type, and a different effect to a creature that critically fails its saving throw; a creature large enough to be in multiple seasons can choose which it is affected by.

Spring (electricity) Spring lightning deals electricity damage. Creatures who critically fail are left numb, becoming Clumsy 2 until the end of their next turn.
Summer (water) A summer monsoon deals bludgeoning damage. Creatures who critically fail are knocked Prone by hurricane winds.
Fall (emotion, mental, wood) Falling leaves deal slashing damage. Creatures who critically fail are gripped by melancholy, becoming Off Guard until the end of their next turn.
Winter (cold) A blizzard deals cold damage. Creatures who critically fail are Stupefied 2 until the end of their next turn as the cold numbs their senses.
