Irritating Seedpod (Greater)

Activate Cast a Spell (add 1 action)

When you crack open this soft, spongy seedpod, you can use it as a catalyst when casting a Mist spell. When you do, irritating pollen fills the area for the spell's duration. Creatures in the area must attempt a DC 24 fortitude saving throw to avoid sneezing uncontrollably. On a failed save, the creature becomes Slowed 1 for 3 rounds. A creature that succeeds at this saving throw becomes temporarily immune to the irritating seedpod's pollen for 10 minutes.
