Guiding Bolt is a 1st level cleric spell. Per the PHB it deals a whopping 4d6 damage if it hits, and the next attack roll made against the target has advantage.
For a 1st level spell, this thing seems grossly overpowered to me. Even the other players in my group have noticed this. A single hit with this thing typically vaporizes most enemies. The one cleric in my group casts only two spells: Cure Wounds, and Guiding Bolt. (Realistically, why would she cast anything else?)
Is this spell actually really overpowered or am I just interpreting it incorrectly?
