If Sett, Brawler is buffed on the battlefield, gets targeted by Smokescreen (giving it -4 until end of turn), then is recalled to base using The Boss legend ability (spending the buff), does it die in base due to having 0 or negative Might?

Ruling: Units do not die from having 0 Might. Units only die if they are damaged and the amount of damage equals or exceeds their Might.

Nuances:

• Having 0 or negative Might from debuffs alone does not kill a unit
• A unit must take damage that meets or exceeds its Might value to die
