Scorching Ray (Acid)

This spell always deals a type of damage determined by your element (earth). In addition, the subtype of this spell changes to match the energy type of your element. You blast your enemies with a beam of acid. You may fire one ray, plus one additional ray for every four levels beyond 3rd (to a maximum of three rays at 11th level). Each ray requires a ranged touch attack to hit and deals 4d6 points of acid damage.
