As you probably already know, many existing items in TERA will become unusable with the introduction of patch 61 on October 10th, as the enchantment system is being overhauled and simplified. But don’t worry, there’s no reason to throw those old materials away!
Your items can be handed in and exchanged for Entropic Emblems and these can in turn be traded in for new items.
A full list of extractable items and the items you can choose from in exchange can be found in this PDF: LINK.
In order to obtain Entropic Emblems, click the extraction button in your inventory and then select the item you wish to extract.
You can then choose how many items from the stack you wish to extract. Note: The selected number of items will be destroyed and you receive the Entropic Emblems in your inventory in return.
You can find out how many Entropic Emblems you will receive from the item descriptions, so you can see immediately what each item is worth.
