Delay Spell

You attempt to delay the casting a spell from a creature you can see within range. The creature makes a Constitution saving throw. On a failed save, the spell is delayed by 1d4 rounds of combat, to which the target position cannot be changed. The spell gains its own initiative immediately following the caster until it goes off. If this spell has a concentration component, the caster of that spell does not have to hold concentration for those rounds. If another concentration spell is cast during that time, and the delayed time ends, the caster can choose which one of the concentration spells to uphold.
