Can Sett's ability be used to save a buffed unit that is exhausted at base and dying from a spell, or does the unit need to be in a showdown?

Ruling: Sett's ability can be used to save a unit regardless of its location, including when the unit is exhausted at base and dying from a spell.

Nuances:

• The unit does not need to be in a showdown for Sett's ability to work
• The ability can save units at base that are dying from spell damage
