The Aromist, A Passive Healing 5E Class

From publisher blurb: Heal Without Having To Waste Your Turn The Aromist is a brand new unique class that specializes in using aura-like effects to heal allies in small amounts over time. Part primal magic and part science, the aromist can fit any role thanks to its three archetypes. The Greenwood creates large clouds of smoke to control the battlefield. The Vesicant poisons enemies and deals large amounts of damage. The Entheogen is an unparalleled healer amongst aromists.
