* This is accessed by going to Start Menu > Item Collection. Players can also select it from the inventory by clicking on Item in the ring menu.&#x20;
* Registering an item for a collection consumes the item. In return, you will get additional attributes.
* If a collection is completed to a certain level, the collection’s level increases. Depending on the level, you receive attributes for your character that are independent of the collection. You can view the rewards for each collection level under Level Reward.
* Some of the Item Collections can be purchased from the Material Contributor NPC located in Sanctum or Pandaemonium. You can buy them using Overdose Shards.<br>
