## Thunderbolt Spell (Metamagic) *You have learned to marry the power of lightning and thunder in your electricity and sonic spells.* **Prerequisite:** Knowledge (nature) 4 ranks, [[Energy Substitution]] (electricity) **Benefit:** This metamagic feat can only be applied to spells that deal electricity or sonic damage. A thunderbolt spell deals half its damage as electricity damage, and half as sonic damage. In addition, creatures who fail their save against a Thunderbolt Spell must make a Fortitude save against the same DC or be stunned for one round and deafened for one minute. Casting a thunderbolt spell is costly, though, and you are automatically dazed for 1 round after doing so. **Level Increase:** +3. In addition, its descriptor changes to include both energy types.
