Corkian Simulators are Mythic Corkian Augments introduced in the 2.0.4 Lootrun Expansion update. They can very rarely be obtained from the Reward Chest after completing a Lootrun. Simulators may not necessarily be available from any given Lootrun's Reward Chest during a given week, but the possible rewards are reset weekly. A Corkian Simulator can be applied while rerolling the Identifications of an item at an Item Identifier in order to prevent the reroll count of the item from increasing (the identification price usually increases exponentially with each subsequent reroll). The Simulator will be consumed upon use. Simulators can be used alongside Corkian Amplifiers, but are incompatible with Corkian Insulators (a Simulator or an Insulator can be used when rerolling an item, but not both at once).
