Choose one spellcasting creature within range. When the spell ends, the creature must make a saving throw whose type is equal to their spellcasting modifier against your spell save DC. On a failure, you steal a number of spell slots from the creature equal to half your spellcasting modifier. These spell slots dissipate after a short or long rest. If the creature has no spell slots, you steal arcane knowledge from them instead, dealing 5d8 psychic damage and learning one spell from the creature. You gain one level of exhaustion after learning a spell this way. When you cast this spell, the level of the spell slots taken must add up to the level of the slot used. If the creature lacks the number of slots to reach the level of the slot used, they take 1d8 psychic damage for every excess level of the slot.
At Higher Levels. If the spell is cast with a slot of 5th or higher, the creature takes an additional 3d8 per slot level above 4th if they do not have spell slots, and take an additional 1d8 if they have spell slots that do not meet the spell's requirements.
