Light/10th

Sealing Bane

Starting at 10th level, you learn to empower your banes to seal a creature's magic.

Whenever a creature you has baned makes a saving throw to maintain concentration, it rolls a 1d4 and subtracts the result from its saving throw.

When a creature you have baned uses its action to cast a spell, and can use your reaction to cast counterspell against that spell, regardless if you can see the creature or it is more than 60 feet away from you. When you cast counterspell in this way, the spell is overpowered to your Magic Limit (or cast at the highest level spell slot you have). Casting it in this way requires no magic points (and no spell slot). Once you use this effect, the bane ends.
