Antimagic Strike (PLAYERS DON'T USE THIS)

YO PLAYERS. DON'T USE THIS. HEYYYYY YOU. DON'T USE THIS.

You have the ability to cast the spell counterspell through an unarmed strike as a reaction. This ability cannot be counterspelled. When you make an unarmed strike, roll a d9. The number you roll is the spell level you "counterspell" at. If it's higher than the spell being cast, you counter the spell. If not, you must roll for it (like how counterspell works).
