Elden Ring: Shadow of the Erdtree continues the base game's tradition of extremely complex questlines that have very little in the way of guidance. Players will almost certainly encounter certain items and NPCs that leave them utterly confused. One such example is the proper use of the Iris of Grace and Iris of Occultation consumables. On their surface, these items appear to have a fairly mundane - and redundant - use. However, in true FromSoftware fashion, players who don't follow a very specific chain of events, will probably never know how to use the Iris of Grace and Iris of Occultation in Shadow of the Erdtree.
