@xiongray It's not an attack. It's range is touch and it's just a save. 01. So no spell attack now. 02. Just a save or half damage and only 2d10 Necrotic damage.
Barkskin and Magic Weapon both stack with Hunter's Mark. At later levels you have better things to use your concentration on, but it is a solid combo early on, depending on your playstyle. If Barkskin is still a touch spell you could put that on the party wizard... and it would stack with the Shield spell... Oh no.
Inflict wounds is now just a bad hellish rebuke. Aside from the con save vs Dex and the necrotic damage vs fire, they do the same thing but one costs an action and the other a reaction
