Synapse Overload

The mind is flooded with psychic energy, causing painful memories and stimuli to overload the mind. Make a spell attack roll, on a successful hit the target must make an intelligence saving throw. On a failure the target takes 3d6 (12) electrical damage and 3d6 (12) psychic damage, halved on a success.

At higher levels: for each level above 3rd, increase the damage of each type by 1d6.
