Anti-Magic Missile

You create six starlight glowing onyx darts of anti-magical force. Each dart hits a creature of your choice that you can see within range. A dart drains 1d4 + 1 spell slots to its target. The darts all strike simultaneously, and you can direct them to hit one creature or several. The darts drain the target's smallest spell slots first. If the final spell slot drained has a larger value than the remaining number that can be drained the spell slots level is reduced by the drain number.

At Higher Levels. When you cast this spell using a spell slot of 9th level you gain three extra darts.
