How to Get the Fierce Deity Set in Tears of the Kingdom

Fierce Deity Armor: Travel to the Akkala Citadel Ruins, southeast of South Akkala Stable. Beware of Gloom Hands; use the broken walls to climb and evade them. Once clear, find a small hole in a wall, crouch through it, and drop down a large hole to find the altar with the armor.

Fierce Deity Mask: Head to Skull Lake in the northeastern part of the map. The right eye of the skull is a tall pillar with an entrance to the Skull Lake Cave at the top. Glide or use Recall on debris to reach it. Inside, defeat Stalkoblins and a Stalnox by targeting its eye. After clearing the enemies, climb the central pillar to find the chest with the mask.

Fierce Deity Boots: Go to the Mount Daphnes area, southwest of Lookout Landing. Find a small body of water with a wooden bridge leading to a large tree stump. Enter the stump and navigate the roots. If you encounter a Like Like, turn around and find vines covering an opening. Go through, climb a vertical root to a ledge, then to another, and a third. Slice through another vine-covered opening to find the altar with the boots.

Fierce Deity Sword: Once you have all three armor pieces, return to the Cephla Lake Cave. Equip the full Fierce Deity armor set, and a previously sealed wall will open, revealing an altar with the Fierce Deity Sword.
