When a buffed unit defends and Sett removes the buff to prevent damage, does the attacker still assign full damage before the buff is removed?

Ruling: Yes, the Sett player can assign the full 5 damage to kill the attacking unit, then remove the buff to save their defending creature.

Sequence:

• All combat damage is assigned first
• Then the buff is removed to prevent lethal damage
• Units dying is checked after all combat damage is assigned

Nuances:

• The defending unit survives even though it would have died without the buff removal
