When a buffed unit that's been debuffed to 1 Might (e.g. through Stupefy) dies and is revived by Sett's ability (which removes the buff), does the unit immediately die again since it's now at 0 Might?

Ruling: No, the unit does not immediately die again. When Sett saves a unit, it also heals the unit, removing all damage marked on it. A unit needs to have a non-zero amount of damage marked on it in order to die, so a 0 Might unit with no damage will not die.

Nuances:

• If the 0 Might unit takes any damage after being saved, it will die immediately since any damage on a 0 Might unit is lethal.
