Valheim Sealed Tower: Roof Entry, Zil & Thungr and the Bronze Chest
On this page
Enter the Sealed Tower through its roof, work down through the guarded floors, and defeat both Thungr and Zil. Zil carries Hildir’s Bronze Chest. The black-stone walls are not a door to mine open, and killing only the large enemy does not finish the encounter.
Standard, unmodded equipment and Hildir quest rules; normal portal restrictions noted where relevant.
Use the roof instead of attacking the stone
Register Hildir’s dungeon locations and approach the Sealed Tower in the Plains. Its black-stone shell is unbreakable. The intended entrance is above, so bring building materials and construct an approach outside the tower’s restricted interior.
Make the climb and return route usable before dropping deep inside. The tower is a surface dungeon rather than a separate loaded cave. You cannot rely on dismantling its interior to create an escape after the fight starts.
Descend as a sequence of rooms
The upper floors contain Fulings, Shamans and traps, including traps concealed under straw. Look at the floor before rushing through a doorway, and clear the next landing before committing to the stairs.
Bring healing and fire-resistance preparation for the spell pressure. If you wear Root pieces for pierce resistance, account for their fire weakness rather than assuming your usual Plains setup handles every enemy in the tower. Return to a cleared floor to recover when needed.
Expect a second enemy after the big target falls
At the bottom, Zil rides Thungr and supplies magic and protection while Thungr attacks at close range. Break through the protection and use openings after the melee swings instead of spending all your stamina on uninterrupted attacks.
Thungr’s death leaves Zil alive as a separate shaman-style threat. Keep watching the arena and deal with him before searching through loot. Zil is the chest carrier; stopping after the large enemy dies is the reason an apparently completed fight can seem to have no quest reward.
Leave with the quest item, not only the trophies
Collect the Bronze Chest as well as the named trophies. It weighs 200, so clear inventory space and plan the external climb and overland route. Under normal rules, the chest cannot use a wooden portal; stone portals and world transport settings are separate cases.
Return it to Hildir for the corresponding stock unlock. Like her other minibosses, this pair’s defeat enables a related raid event even before you hand over the chest. Have defenses and repair supplies ready at the base you return to.
