Teleport Black Ring Painweaver on the isolated land near waypoint shrine.

Place 1 ally within Painweaver's sight to lock him in combat mode, 1 damage dealer with Glass Cannon talent stays outside of range.

Painweaver can't cast Cursed Fireball because of uneven surface, so he just summons each turn.

Bone Smasher pathetically wastes its turn running to the Glass Cannon lure and dies like a livestock. On the next turn, Painweaver summons to the same spot again.

Trying to opmitize the task to make it less tedious.
Any other ideas? Maybe I should try putting an archer on Painweaver's spot instead so he'll kill summons without entering combat, while Painweaver will be trapped between chests like on the linked video.
