Delay

You slow the effects of a spell cast around your person.

When a spell or ability is activated that targets an area that you are within and you can see the caster, you may use your reaction to slow the process of that spell. Instead of activating when cast, the spell triggers the next time you end your turn, or when you lose concentration on this spell, whichever comes first.The affected spell is still considered cast for the purposes of spell slots and concentration, and it cannot be moved or changed from the parameters set when first cast.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the affected spell or ability doesn't trigger for 1 extra round for every two spell slot levels above 5th.
