Aura of Rotting Spores

Needs to be A Spore druid level 3+

Your body constantly exudes a faint haze of necrotic spores, feeding on your enemies and nourishing your slime-like form.

Spore Aura. When you activate your Symbiotic Entity feature, you can choose to also release your Aura of Rotting Spores. The aura radiates 5 feet from you and lasts while Symbiotic Entity is active.

Necrotic Decay. A hostile creature that starts its turn in the aura, or enters it for the first time on a turn, must succeed on a Constitution saving throw (DC = 8 + your proficiency bonus + your Wisdom modifier) or take 1d4 necrotic damage.

Rotten Sustenance. When a creature takes damage from this aura, you regain hit points equal to half the necrotic damage dealt.

Scaling. The damage increases by 1d4 at 6th level (2d4), 10th level (3d4), 14th level (4d4), and 18th level (5d4).
