SRD:Energy (Epic Spell Seed)

This seed uses whichever one of five energy types the caster chooses: acid, cold, electricity, fire, or sonic. The caster can cast the energy forth as a bolt, imbue an object with the energy, or create a freestanding manifestation of the energy. If the spell developed using the energy seed releases a bolt, that bolt instantaneously deals 10d6 points of damage of the appropriate energy type, and all in the bolt’s area must make a Reflex save for half damage. For each additional 1d6 points of damage dealt, increase the Spellcraft DC by +2. The bolt begins at the caster’s fingertips. To imbue another creature with the ability to use an energy bolt as a spell-like ability at its option or when a particular condition is met, increase the Spellcraft DC by +25. The caster can also cause a creature or object to emanate the specific energy type out to a radius of 10 feet for 20 hours. The emanated energy deals 2d6 points of energy damage per round against unprotected creatures (the target creature is susceptible if not separately warded or otherwise resistant to the energy). For each additional 1d6 points of damage emanated, increase the Spellcraft DC by +2. The caster may also create a wall, half-circle, circle, dome, or sphere of the desired energy that emanates the energy for up to 20 hours. One side of the wall, selected by the caster, sends forth waves of energy, dealing 2d4 points of energy damage to creatures within 10 feet and 1d4 points of energy damage to those past 10 feet but within 20 feet. The wall deals this damage when it appears and in each round that a creature enters or remains in the area. In addition, the wall deals 2d6+20 points of energy damage to any creature passing through it. The wall deals double damage to undead creatures. For each additional 1d4 points of damage, increase the Spellcraft DC by +2.

The caster can also use the energy seed to create a spell that carefully releases and balances the emanation of cold, electricity, and fire, creating specific weather effects for a period of 20 hours. Using the energy seed this way has a base Spellcraft DC of 25. The area extends to a two-mile-radius centered on the caster. Once the spell is cast, the weather takes 10 minutes to manifest. Ordinarily, a caster can’t directly target a creature or object, though indirect effects are possible. This seed can create cold snaps, heat waves, thunderstorms, fogs, blizzards—even a tornado that moves randomly in the affected area. Creating targeted damaging effects requires an additional use of the energy seed.
