The small outbuilding connected to Blackthorne's castle in Central Ilshenar has 3 golems and 6 controllers in it. One of the best ways to get gears is to have a party of 2 or 3 mages (one of these works well as an archer or dexxer instead, but they got to have resist magic). One person concentrates on the golems, another on the controllers, and if a third present, they help on both aspects of the fight, and keep an eye out for paragons.
One person can do it with a mage, standing outside and letting the controllers come to you (often being followed by the golems, but you got to risk running in every once and a while to get golems down to you (the 2 rooms, and at the door to the stairs to level 3 of the building).
