A unit who Never Heals is an unfortunate entity, dispossessed of the favors that others have. Each turn, units without this trait recover all of their lost Hit Points once, as long as they don't have a Disease. Having this trait thus sucks.

If a unit with this trait is also Sacred, they may benefit from a Bless effect or two to lift this penalty. Reforming Flesh lifts this trait from the Undead, while Reconstruction lifts this trait from the Inanimate who aren't Undead.

On that note, a fellow with the Undying bless benefits less from it if they have the "Never Heals" trait. The Undying fall apart at the end of the battle if they have negative HP, unless they're Undead and don't have this trait.
