Delayed Poison

You attempt to infuse a creature within range with a poison that has no effect until you activate it. The target makes a Constitution saving throw. On a failure, it is now infused with the inert poison.

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 another Constitution saving throw. It takes 8d12 poison damage on a failed save, and half as much on a successful one.

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