Aura of Spores

An aura of necrotic spores surrounds you which damages enemies and heals you in return.

At 3rd level a cloud of spores radiates 5 feet out from your body. The spores are difficult to see and require a passive perception of 15 to notice them. The spores are considered invisible to any creature who is more than 10 feet from you. Any hostile creature who enters the area for the first time or starts its turn there must make a DC15 Constitution Saving Throw or take 1d4 necrotic damage, or half as much on a successful save. You are healed by an equal amount to the damage dealt this way.

Damage dice will increase by 1d4 at 6th level, 9th level, 12th level and 15th level to a maximum of 5d4.
