Casting Time: 1 action
Range: 30 feet
Components: V, S
Duration: 1 hour

You fire a bolt of mental energy at a creature you can see within range. It must succeed on a Wisdom saving throw or become mentally taxed. At the start of each of its turns while it is concentrating on any effect, the taxed creature takes 2d12 psychic damage and has its power and spell save DCs reduced by 4 until the end of its next turn. Once the target has taken this damage five times, the spell ends.
