The Talisman of All Crucibles effect
Once you reach the bottom, you’ll spot a lift, which takes you to the Ancient Ruins – Grand Stairway Site of Grace. However, if you want to obtain the Talisman of All Crucibles, you need to go past the lift and check the back of the cliffside section. There are a couple of enemies here and, once you’ve eliminated them, you can go through the crawlspace. Inside is a chest that contains the reward.
What makes the Elden Ring: Shadow of the Erdtree Talisman of All Crucibles quite unique is that it grants the effects of all Crucible-type accessories. These include the Crucible Scale Talisman (i.e. reduces critical damage taken), Crucible Knot Talisman (i.e. reduces headshot damage taken), Fine Crucible Feather Talisman (i.e. improves backstep but increases damage taken), and others. One equipment provides five or more buffs on its own.
