The Travelers Thunderbolt

You generate twin bolts of lightning from your hands or eyes (your choice), which forth to strike up to two targets in range. A ranged spell attack is required to strike a hostile target (willing creatures mav be hit automatically). When struck, each bolt either deals 3d6 lightning damage or heals the target for 1d8 points of damage, your choice. A critical hit doubles the damages or healing, but creatures that are automatically struck cannot be critically hit.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, each bolt deals additional 1d6 damage or 1d8 healing, for each level above 3rd.
