Arcane Spear

You hurl a spear made of magical force at one creature within range. Make a ranged spell attack against the target. If it hits, the spear does 3d10 force damage. If the target is a spellcaster, the hit also wipes out one of its available, lowest-level spell slots as if the spell had been expended.

Enhancement: For each spell slot used higher than 3rd level, damage increases by 1d10. When you cast arcane spear using a spell slot of 6th level or higher, a hit also wipes out two of the target’s spell slots instead of one.
