If Sett Brawler has a buff and is reduced to 1 Might by Smoke Screen, does he die when the buff is later removed?

Ruling: Sett Brawler will not die when reduced to 0 Might after the buff is removed. Units only die when they have non-zero damage on them, not from having 0 Might alone.

Sequence:

• Smoke Screen reduces Sett Brawler to minimum 1 Might while buffed
• When the buff is removed (e.g., by activating Sett leader ability), Sett becomes 0 Might
• Sett survives at 0 Might unless he takes any non-zero damage

Nuances:

• A unit at 0 Might will die if it takes any amount of non-zero damage afterward
• Removing Sett's buff via the leader ability also increases his Might, which should be considered in the calculation
• When Sett is recalled to base, damage is removed but Might modifiers remain (the unit retains modifiers as the same game object)
