Delay Poison

You infuse a creature within range with a poison that has no effect until you activate it. 

When the spell ends, either because your concentration is broken or because you decide to end it, the poison activates, and the target must make a Constitution saving throw. 

On a failure, the target becomes poisoned for 1 hour and takes poison damage depending on which poison was used in the casting of this spell. On a success, the target does not become poisoned and only takes half damage.

If the creature is targeted by any effect that would cure the poisoned condition, the spell ends without the poison activating.
