Wall of Fire

(or special) This spell creates a vertical sheet of flames in an area indicated by the caster, which is either a wall of flame up to 20' in length per caster level, or a ring with a radius up to 5' per caster level. The caster may choose to make the wall smaller if desired. The wall may be up to 20' tall (as desired by the caster and/or constrained by the ceiling). The entire wall must lie within the range given above. One or both sides of the wall may be hot, as determined by the caster at the time of casting. Once created, the wall cannot be moved or changed. Any creature within 20 feet of a hot side of the wall will suffer 1d4 points of damage each round, or 2d4 points if within 10 feet. Damage is applied on the round the spell is cast and each round thereafter. Actually passing through the wall causes 2d6 points of damage, plus 1 per caster level, even if the side the character or creature entered from was not a hot side. Undead creatures are particularly susceptible to this spell, and suffer twice the damage described above. If the caster evokes the wall so that it appears where creatures are, each creature takes damage as if passing through the wall; a save vs. Spells is allowed, with success indicating that damage is rolled as if the creature is within 10' of the wall. The caster may choose to maintain the spell indefinitely (within reasonable limits of endurance) by concentration, or may cast it with the standard duration of 1 round per level, at their option.
