Dragon Counter

As a reaction in response to a draconic creature casting a spell or using a magic effect, you quickly attempt to produce a countercharm nullifying it's effects. If the creature casting the spell is of a level or CR equal to or less than your current player level, the spell or effect immediately fails and has no effect. If the creature has a higher CR or level than your own you must pass a wisdom check with a DC equal to 12 + the difference between yours and the creature's level/CR, or your spell fails and the creature's continues.
