Eldras Grim Betrayel

You reach out, ripping at their sanity and sense of trust. The target needs to make an intelligence saving throw or takes 2d8 psychic damage, half as much on a successful saving throw. If the creature is charmed by you, it takes 4d8 instead. If it is charmed by you and considers you a friend beforehand, the target automatically fails the saving throw and takes maximum damage.

At Higher level: Whenever you cast this spell using a spell slot of 2th level or higher, the damage increases by a d8 for each slot above 1st.
