I have just helped a fellow 5e player set up their life domain cleric. However, we are both unsure whether the Disciple of Life feature should apply to them casting revivify, which they are able to cast as the party is level 9.
The DM is unavailable at the moment so I thought I’d ask the question to the greater world.
Best Answer
Yes it should apply
The life domain cleric disciple of life states (emphasis mine):
And the Revivify spell states that:
A dead creature has no hit points. Revivify causes the creature to now have 1 hit point. This certainly qualifies as "restoring hit points".
So reviving a character with a 3rd level Revivify would start them with 6 hit points: 1 from revivify and 5 from disciple of life (flat 2 plus 3 from the level of the spell slot that was used).
