You attempt to interrupt a creature in the process of casting a spell. The target spell must have a casting time of 1 action or longer. 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 a spellcasting ability check contested by the target's spellcasting ability check. both you and the target get a +1 bonus to their check for every level you are casting your spells. If the counter spell succeeds or in case of a tie they effectively stop that spell from occurring leaving the caster the option of finalizing their turn or using the last few seconds to fire off a cantrip or a weapon attack as part of the same action.
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.
