If Lee Sin (Ascetic) has multiple buffs and I play Wallop to spend one buff to ready him, does he keep his remaining buffs or do all buffs go away?

Ruling: Only one buff is spent by Wallop. Lee Sin retains any remaining buffs after spending one to pay for Wallop's effect.

Nuances:

• Each buff on Lee Sin is a separate entity, not a stacking counter
• You can play multiple different copies of Wallop by spending multiple buffs from Lee Sin
• You cannot play the same copy of Wallop multiple times
