If Sett with 5 might and a buff gets Smoke Screened, and the buff is removed to save him (bringing him to 0 might), will he die at 0 might given the new errata that Sett replacement heals?

Ruling: Sett will not die at 0 might. A unit only dies from 0 might if they also have damage on them.

Sequence:

• Sett gets Smoke Screened while at 5 might with a buff
• Buff is removed to save him, bringing him to 0 might
• Sett replacement effect heals him to 0 damage
• Sett survives at 0 might and 0 damage

Nuances:

• 0 might alone does not kill a unit; they must have both 0 might AND damage to die
