Rise of the Rune Lords
School evocation; Level Sor/Wiz 5
Casting Time 1 standard action
Range close (25 ft. + 5 ft./2 levels)
Saving Throw Reflex half; Spell Resistance yes
A blast of quintelemental energy shoots from your fingertips in a cone, inflicting 1d6 points of damage per level (maximum 15d6). This energy affects creatures as the energy type to which they are most vulnerable, if applicable. Thus, the spell affects a creature with resistance to fire 30 as if it were an energy type other than fire. Creatures with a vulnerability to an energy type, such as cold creatures who suffer a -10 penalty to their saving throws against fire, suffer as if exposed to their vulnerability. Even if a creature has both protection and a vulnerability to one energy type, this spell bypasses the protection and still affects the vulnerability. So if a wizard cast protection from energy (fire) on a frost worm, quintelemental blast would ignore the protection spell, and the creature would still suffer a -10 penalty to its saving throw.
Creatures with resistance or immunity to all energy types have
appropriate protection from the damage this spell inflicts. A cleric carrying the effects of five different resist energy spell (for all five energy types—acid, cold, fire, electricity, and sonic) subtracts 12 points of the damage she normally would suffer from this spell.
