Arcane Turmoil

Arcane Turmoil  2nd-level abjuration  [Complete Mage] [Wiz]

Choose a creature you can see within range. That creature must make a Wisdom saving throw. On a success, the spell has no effect.

On a failure, the target loses 1 spell slot from the highest-level spell slots remaining to it, as if it had been used to cast a spell.

For example, if the target has 4 1st-level spell slots, 2 2nd-level spell slots, and 1 3rd-level spell slot when it fails its saving throw, it loses its 3rd-level spell slot.

At Higher Levels. When you cast arcane turmoil using a spell slot of 3rd level or higher, the target loses another of its highest-level spell slots for each slot level above 2nd you use to cast arcane turmoil.
