When Icathian Rain targets 6 times and Spirit's Refuge is on the board, does the user have to recycle a ruin for each buffed unit targeted, or is it a one-time cost?

Ruling: You must pay the cost (recycle a ruin) for every time you target a buffed unit with Icathian Rain while Spirit's Refuge is on the board, not just once.

Sequence:

• Icathian Rain targets up to 6 times
• Each time it targets a buffed unit, Spirit's Refuge triggers
• The cost must be paid separately for each buffed unit targeted
