Ancient Thunderbolt

With a resonant chant invoking the power of ancient storms, you summon a bolt of thunderous energy from the skies. The bolt crackles with raw, primal power as it streaks towards a target within range. Upon impact, the target must make a Dexterity saving throw. On a failed save, the target takes 1d8 lightning damage and is stunned until the end of its next turn. On a successful save, the target takes half as much damage and is not stunned.

The bolt’s impact creates a thunderous boom audible within 100 feet, potentially alerting nearby creatures to your presence. The ground around the target is scorched and crackles with residual energy, leaving a lasting mark of the spell’s ancient power.
