The Sanctuary of Trials (also called the Shrine of Trials) is an early dungeon near Mushroom Village. It is unlocked with the Chapel Key and rewards the Axe and Dagger, a fast paired weapon.
The dungeon's two signature puzzles are the Gaze King illusion wall and a pair of stone block pressure-plate rooms.
Getting the Chapel Key
From the Mushroom Village Beacon, go right and cross the bridge, defeating the cultists around the bonfire. Find the stone arch with steps, and look through the empty doorframe to reveal a hidden statue with a rope. Interact with the rope to collect the Chapel Key.
Return to the beacon and go left to the Grisha hunter camp, then use the key on the locked door to enter the Shrine of Trials.
The Gaze King statue
After defeating four cultists, find the statue with the inscription “Gaze upon your king so true, back and back you shall pass through.” Stand facing the statue and walk backwards toward the wall behind you. The illusory wall disappears and the path opens.
Stone block puzzles and reward
The first puzzle uses one block and one pressure plate: hit the block twice to slide it onto the plate. The second uses two blocks and two plates. Start with the left block and hit it to move left, then straight, then right. Move to the right block and hit it once onto the first plate, then return to the left block and hit it onto the second plate.
Defeat the Spear Knight guarding the slab, then interact with it to claim the Axe and Dagger. For more on traversal and loot, see fast travel and Tarstone locations.
