As two actions, you are surrounded by invisible necrotic spores in an aura shaped as a sphere. Until the spell ends, the aura moves with you, centered on you. An enemy creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Fortitude saving throw.

On a failure, it takes 2d8 poison damage and is poisoned until the end of its next turn.

On a critical failure, it takes twice as much damage.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

Augment

You can increase the damage by 1d8 for every two additional mana expended.
