The short version

What matters

  • •Rescuing Folan from the cooking pot in the ice troll cave and freeing Vigi from his cage in the Ice Giant's Lair.
  • •Slaying the Ice Giant Myrhyff alongside Hjalmar in the southern coastal cavern to resolve "The Lord of Undvik."
  • •Looting the chest in the Clan Tordarroch Forge cave to obtain the High-quality smithing tools and Deithwen.

Common mistakes

  • •Stepping on the snow patches or attacking Myrhyff before unlocking Vigi's cage, causing the giant to smash the cage and kill Vigi.
  • •Postponing "The Lord of Undvik" until embarking for "The Isle of Mists", which permanently fails the quest.
  • •Finishing "The Lord of Undvik" before bringing the nails and twine to Octo, causing him to permanently vanish from the warship hull.

What you can skip

  • •Searching for merchants, repair benches, or craft services on Undvik, as the island is devoid of vendors.

Walkthrough May be incomplete

The area in the order you play it. Tick things off as you go: they tick off in the checklists below too.

  1. 1

    Landing at the Coast

    When you steer your boat toward the coast of Undvik near Marlin Coast during The Lord of Undvik, you will spot fast travel signposts and autosaves functioning as save points across the isle. As you approach the giant's warship shipwreck on the shoreline, a cutscene plays depicting the Ice Giant Myrhyff feeding Sirens. Defeat the Sirens circling outside the hull, then search through the planks, crates, and beachfront debris with your Witcher Senses to collect scattered nails and twine.

    Watch out: Finish "The Lord of Undvik" before starting "The Isle of Mists", or this entire secondary quest fails permanently.

  2. 2

    Meeting Octo in the Hull

    Step inside the unfinished warship hull on the coast to meet the deranged Clan Tordarroch survivor named Octo. Speak with him and hand over the nails and twine you scavenged to view an optional dialogue scene. Make sure to complete this interaction right away, as Octo leaves the hull permanently once the overarching quest concludes.

    Watch out: If you do not hand the nails and twine to Octo before concluding "The Lord of Undvik", he vanishes from the ship hull and locks out this exchange.

  3. 3

    Investigating the Trail Inland

    Follow the tracks and footprints leading inland past the Abandoned Village to continue the search. Along this path toward the troll cave, enter a cavern and search beside the dead Skelliger corpse resting on the ground. Pick up the Horn of Hornwall sitting right next to the fallen body before pushing deeper into the wilderness.

  4. 4

    Rescuing Folan at the Ice Troll Cave

    Continue along the tracks toward Urskar, where you will find an ice cavern dungeon inhabited by ice trolls. Head inside the cave to locate Folan, who is trapped inside a cooking pot by the trolls.

  5. 5

    Raiding the Clan Tordarroch Forge

    Progress through the mountain paths past Urskar Ruins until you reach the Clan Tordarroch Forge cave dungeon, an abandoned site lacking any active merchants, vendors, or craft services. Enter the forge cave during or after "Master Armorers" and eliminate the guarding cave troll. Open the chest situated inside the cave to recover both the High-quality smithing tools and the relic sword Deithwen.

  6. 6

    Fighting Through Dorve Ruins

    Traverse the mountain trails forward to the Dorve Ruins, where you will locate Hjalmar an Craite. Join him in battling the hostile Sirens swarming the area as he prepares for the assault against the giant. Once the monsters are cleared, join forces with Hjalmar to advance directly toward the monster's sanctuary.

  7. 7

    Infiltrating the Ice Giant's Lair

    Navigate the mountain pass and icy caverns to reach the coastal cave at the Dorve Ruins on the south end of Undvik, which serves as the Ice Giant's Lair. Inside, locate Vigi the Loon trapped in a cage while Myrhyff sleeps. Tread carefully around the snow patches so you do not awaken the beast prematurely, and use your Witcher Senses to find a chest on the left side of the cave containing the Key to Vigi's cage.

    Watch out: Do not attack or wake the Ice Giant before unlocking the cage; if awakened, he smashes the cage, killing Vigi and making the key unusable.

  8. 8

    Slaying Myrhyff

    Free Vigi from his enclosure and confront the awakened Ice Giant Myrhyff alongside Hjalmar inside the southern coastal cave. Bring down the towering beast during the quest's climax, then search his remains to loot Monster parts, elemental reagents, and a Lesser Glyph of Aard. With the Ice Giant defeated, your expedition on Undvik is brought to a close.
