The Talisman of All Crucibles is a talisman added in Shadow of the Erdtree.
A giant mass of intermingling Crucible attributes.
Reduces damage taken from critical hits and head shots and improves the effectiveness of rolling and backstepping, but also increases damage taken at all times.
Rumored to have sprouted upon giants and is known as the "mother of Crucibles" in ancient tower lore.
Found in a treasure chest in the western Ancient Ruins.
If you have the Ancient Ruins, Grand Stairway Site of Grace unlocked, start there and take the nearby lift down; then, enter the square passage towards the south by using Torrent's double jump, using the adjacent pile of rocks to gain enough height to do so. Through the passage is a room containing the treasure chest.
If you only have the Rauh Ancient Ruins, West grace unlocked, start there and enter the tunnel to the southwest. Follow the tunnel's left wall until you reach a lift; take it up and then round the corner to the left. Below the cliff is a walkable lattice structure; jump down onto it and follow the path. At the intersection, enter the room to your left, which contains the aforementioned square passage and the elevator to the Grand Stairway grace.
It simultaneously grants the beneficial effects of the Crucible Scale Talisman, Crucible Knot Talisman, Crucible Feather Talisman, and the Fine Crucible Feather Talisman together, but also increases damage taken.
