So as you may have noticed the Shadow Item quest has not changed according to the intended plan. There is good news and bad news about shadow items on their place in Renewal.
At the studio's request we will stop the implementation of Shadow Item quests for Chaos and Thor.
At the studio request we are preparing a drops plan to add most of the first and second generation shadow items to instance drops all over the game. We have officially been requested to prepare and plan to upgrade/expand the loot of every daily instance in the game with shadow items. The current timeline for this is to implement the first changes for our anniversary event this year.
Broadly speaking the shadow items will matching difficulty curves of instances (if an instance is easy don't expect the best items there.) Currently the list of shadow items is being translated from Korean and it may take a couple weeks before they finish and we can get into the details stage of what goes into what instances with what monsters.
