Can you use Sett's Legend Power to protect a unit from Cull the Weak, and does it still work if the unit is already in base?

Ruling: Yes, Sett's Legend Power can protect a unit from Cull the Weak as long as the unit has a Buff and you can pay the power plus exhaust costs. Sett triggers when a unit would die, regardless of whether it's from an attack or event spell.

Sequence:

• Cull the Weak attempts to kill a buffed unit
• Sett's power triggers ("when they would die")
• If the unit is already in base, you skip the recall portion of Sett's effect
• The unit survives

Nuances:

• The unit must have a Buff for Sett's power to work
• You must be able to pay the power and exhaust costs
• If the unit is already in base, only the survival effect applies (recall is skipped)
