When Icathian Rain deals lethal damage to a unit with Sett Legend protection, does the protection trigger immediately, and can the remaining Icathian Rain triggers still target and kill the unit after it recalls and heals?

Ruling: You choose all 6 Icathian Rain targets at once before any resolve. When the 3rd trigger deals lethal damage, Sett Legend triggers to recall and heal the unit, but the remaining 3 triggers still resolve and can kill the unit again if the damage is sufficient.

Sequence:

• Choose all 6 Icathian Rain targets at once
• Icathian Rain triggers begin resolving one at a time
• When the 3rd trigger deals lethal damage, Sett Legend protection triggers
• Unit recalls to base and heals
• Remaining 3 Icathian Rain triggers resolve and deal damage to the unit
• If total remaining damage is lethal, the unit dies
