When casted roll a D10 to determine damage and then roll a D8 to determine whether it does psychic damage or elemental damage. If a perfect D8 is rolled it does both psychic and elemental damage and must roll another D10 to determine damage. Damage increases when used at a higher spell level (uses 1 spell slot) The elemental damage is chosen by the dm or whatever the player's chosen element is. The possible elements are fire, cold, force, acid, and lightning.
