How to Beat Zil & Thungr in Valheim: The Sealed Tower's Duo Miniboss

 

    Zil & Thungr are, per the wiki, "the first creatures in Valheim that work as a duo" — an aggressive miniboss pairing sealed inside a Sealed tower in the Plains. Thungr carries 4,200 health and swings a club; Zil carries 2,400 health and throws fire while shielding his partner — 4,200 + 2,400 = 6,600 combined health across the encounter. Here's every documented attack, cooldown, range, and drop for both, with the source's own gaps stated plainly rather than filled in.

 

Who Are Zil & Thungr

 

    Location, faction, and combined health for the Sealed tower duo. Source: Valheim Fandom wiki.

 

    Both are tagged Aggressive, not tameable, and immune to Spirit damage — no other resistance or weakness is listed for either. The infobox reserves image slots for 1★ and 2★ variants, but no starred health or damage figures are given anywhere on the page, so treat every encounter you meet as these base numbers unless you personally observe otherwise. The pair shares a joint internal ID, GoblinBruteBros, on top of each half's own separate ID — which matters later, since it's what lets the two be separated at all.

 

Thungr's Club: Attack and Rage Attack

 

 

    Thungr does the melee work, and the wiki documents exactly two moves for him. His regular Attack swings his club through a 4-meter, 70-degree horizontal arc for 150 Blunt, 100 Chop and 40 Pickaxe damage — 150 + 100 + 40 = 290 total per hit — usable within 3 meters every 2 seconds. Landed every cycle, that's 290 ÷ 2 = 145 damage per second sustained from the basic swing alone. The wiki also notes the Attack "has two variations: a regular swing and delayed swing," with a documented timing gap of approximately 0.297 seconds between them — worth knowing if you're timing a dodge off the first swing you see.

 

    His Rage attack is the bigger single burst: three ground slams stepping forward, each reaching 4 meters in a 60-degree vertical arc, dealing 130 + 100 + 40 = 270 damage per hit, three times, for 810 total damage in one sequence — usable within 6 meters every 20 seconds.

 

Zil's Fire and Shield

 

 

    Zil is the ranged half. His Fireball deals 20 Blunt plus 100 Fire — 20 + 100 = 120 total damage and applies Burning — on a 12-second cooldown, usable within 20 meters. The projectile "travels at 15 meters per second for up to 4 seconds before despawning," capping its reach at 15 × 4 = 60 meters, with a spread of 4–20 degrees off his aim. Landed every cycle, that's 120 ÷ 12 = 10 damage per second sustained — far lower than Thungr's melee, consistent with Zil's role as support rather than the main damage source.

 

    That support role is Protect: a barrier over allies within a 6-meter radius, "negating up to 100 damage before breaking or lasting for up to 40 seconds," on a matching 40-second cooldown, castable from as far as 60 meters away. Because the cooldown equals the duration, Zil can keep near-continuous shielding up while he stays alive and in range. One switch matters for fight order: "When Thungr is killed, Zil is left alone and his attack pool is reverted to that of a regular Fuling shaman." The specific numbers for that reverted moveset aren't given on this page — undocumented here, so don't assume it matches the Fireball/Protect figures above once Thungr is down.

 

Drops, Solo Spawns, and Trivia

 

 

    Kill both and the drop table lists Zil trophy and Thungr trophy at 100% each, plus Hildir's bronze chest at a documented quantity of 1. The wiki's Notes section confirms "Zil is the one that drops Hildir's bronze chest," though the chest's own drop chance isn't separately spelled out beyond that quantity — treat whether it's a flat 100% or lower as undocumented.

 

    Despite being built as a duo, the two have separate internal IDs — GoblinShaman_Hildir for Zil, GoblinBrute_Hildir for Thungr — and the wiki notes this means "players can spawn them separately thanks to their Internal IDs," even though the intended encounter pairs them. A few documented trivia points: their trophy descriptions make Zil older than Thungr despite his smaller size, and the wiki records that "Zil is jealous of Thungr's strength, and Thungr is jealous of Zil's magical power." The wiki also credits the characters "Master Blaster" from the 1985 film Mad Max: Beyond Thunderdome as inspiration, and notes that Zil can still cast his elemental attacks while swimming.

 

Fast tips

• Thungr's basic Attack lands 290 damage every 2 seconds within 3m — stay outside that range when you can, since it's his most frequent hit.
• His Rage attack totals 810 damage across three hits within 6m, every 20 seconds — a serious punish if you're caught close when it triggers.
• Zil casts Fireball only within 20m (its projectile then carries up to 60m: 15 m/s × 4s) for 120 total damage — closing distance fast denies him his only ranged option.
• Killing Thungr first reverts Zil to a regular Fuling shaman's attack pool — documented, though this source doesn't list what that pool actually does.
• Protect's 40s cooldown matches its 40s duration, so expect near-continuous shielding on anyone within 6m while Zil is alive.
• No starred (1★/2★) health or damage figures are documented for either half — treat every encounter as the base stats above.

 

Running your own Valheim server

 

    Clearing a Sealed tower properly benefits from a persistent, always-on world — nobody wants to lose the fight because the host had to log off mid-Rage-attack. A gamever Valheim server keeps the world running for up to 10 players, with one-click backups so a bad pull against a 6,600-combined-health duo doesn't cost your group's whole session.

 

Conclusion

 

    Zil & Thungr are Valheim's first duo miniboss, splitting 6,600 combined health (Thungr's 4,200, Zil's 2,400) between a melee bruiser and a ranged support caster inside a Plains Sealed tower. Thungr's Attack deals 290 damage every 2 seconds within 3 meters, and his Rage attack adds 810 more across three hits every 20 seconds within 6 meters. Zil casts Fireball within 20 meters (its projectile carrying up to 60) for 120 damage on a 12-second cooldown, backed by a Protect shield that stays up almost continuously thanks to matching 40-second duration and cooldown. Kill Thungr and Zil reverts to a standard Fuling shaman's kit — documented, even if this source doesn't detail what that reverted moveset does. Both drop their trophy at 100%, and Zil alone carries Hildir's bronze chest. With no starred variants documented for either, what's listed here is the complete stat picture the wiki provides.
