When you learn this spell you determine its energy type and attack type. Once chosen, you cannot change it unless you learn the spell again and choose a different combination of energy type and attack type. The attack type determines the spell’s range, area, saving throw and level. Each combination is a different spell on your list of spells.
Energy types are: acid, cold, fire, electricity and sonic. Attack types are: touch, ray, line and burst.
Acid: The spell deals 1d4 points of damage per caster level and it deals half that damage in the following round. If the spell allows a saving throw, succeeding in the saving throw cancels the extra damage.
Cold: The spell deals 1d6 points of damage per caster level and the target(s) is(are) slowed for 1d4 rounds. If the spell allows a saving throw, succeeding in the saving throw cancels the slowing effect.
Fire: The spell deals 1d6 points of damage per caster level and it sets the target(s) on fire. If the spell allows a saving throw, succeeding in the saving throw prevents the target from being caught on fire. The DC for extinguishing the fire on further rounds is the same used for the spell.
Electricity: The spell deals 1d6 points of damage per caster level and the target(s) is(are) dazed for one round. If the spell allows a saving throw, succeeding in the saving throw cancels the dazing effect.
Sonic: The spell deals 1d6 points of damage per caster level and the target(s) is(are) stunned for one round. If the spell allows a saving throw, succeeding in the saving throw cancels the stunning effect. Sonic damage deals only half damage to living creatures, but full damage to objects.
