→Sources of permanent items
Unfortunately, most of such items can not be placed into most containers (except those related to the same quest), and are of limited use.</br>
Some quest-related items are droppable and are never removed from alias, usually because they are related to infinitely running (and in most times hidden from player)
quest. Such items are fully permanent.
When a quest item is removed from alias (usually after its quest ends), it is no longer a fully permanent item. However it may stay permanent until dropped. Also some items existing at the beginning of the game are permanent until dropped. Furthermore, sometimes seemingly common items gain permanent (until dropped) properties due to undefined circumstances</br>
