When a Droid is discarded from any arena, attach Kuiil's Patience to one of your non-Droids.
Equipped non-droid gets Focus 1.
Equipped Kuiil also gets "Each of your Droids in this arena gets Damage Control 1".
Keywords
Damage Control
Damage Control X: A cumulative, triggered ability that means, "When your build step starts, you may remove up to X damage counters from this unit."
Equip
Equip: A selective effect on Equipment activated during the build step that means, "Attach this Equipment to a unit. Play only during your build step." You can pay the Equip cost only once per turn.
Focus
Focus X: A cumulative ability triggered by the initial dice roll that means, "When you roll at least one natural five with this unit's attack dice before re-roll, this unit gets +X power for its next attack." Only the first natural "5" counts. A five rolled after re-roll doesn't matter. Focus applies only to dice rolled for an attack, not to dice rolls for abilities like Retaliate. Accuracy can't increase the die roll to a natural "5."
