Upon casting this spell, the caster opens up a "personal" planar rift, within his own body. The caster can choose any plane that he is aware of and has material from or related to (eg., a potion of healing would work to connect to the positive material plane). This material is considered to be the material component of the spell, and is consumed in the casting.
He may then emit energies from this plane at 12d6 damage. After a month of practice with this spell, the caster learns to duplicate planar phenomena on the prime material plane. This could mean: a wizard connects to the plane of fire regularly, and after a month of practice he can cause fields to explode into fiery combustion at will (see the Manual of the Planes for planar phenomena).
This spell is about as "trademarked" as it could possibly be non-legally: only Surge, the gold dragon Nexus, and Elminster know of it in the Forgotten Realms (both are good spell trading buddies). But, seeing that eight of Surge's spellbooks have taken to the wind, go ahead, make it about as rare as wish.
