Aid facilitates the medical care with powers to assist in treating a wounded or poisoned person.
This spell provide you and your allies with short-term benefits and boosts healing. It helps heal allies that have taken damage by giving you new fighting resources for many subsequent battle rounds. You can also use it to protect against death’s door, which is the most common save used outside of combat in D&D 5e, so this is an alternate way to get out of dicey situations as well!
