Delay

You attempt to delay a creature in the process of casting a spell. The target of this spell is delayed as long as you maintain concentration and has no effect. If it is casting a spell using a higher spell slot than the one you used to cast Delay, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a success, the creature's spell is delayed and has no effect.

If you lose concentration, this spell's duration ends, or you willing release this spell, the target's spell takes effect as usual.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the delayed spell has no effect if its level is less than or equal to the level of the spell slot you used.m
