Twilight Counterspell

You attempt to interrupt a creature in the process of casting a spell. If the creature is casting a spell of 3rd level or lower, its spell fails and has no effect. If it is casting a spell of 4th level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a success, the creature's spell fails and has no effect.

If the person casting this spell is a Twilight Cleric and is within an already operating Twilight Sphere, the range is increased to 300 feet, subject to whatever terrain or obscuring effects might block their sight. If the target of the original spell is within the Twilight Sphere, the caster of this spell gets a +1 Bonus on their DC to counter a spell higher than 3rd level.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the interrupted spell has no effect if its level is less than or equal to the level of the spell slot you used. As mentioned above, if the target of the original spell is within the Twilight Sphere, the caster of this spell gets a +1 Bonus on their DC to counter a spell of 4th level or higher (only one bonus can be granted per casting of Twilight Counterspell).
