Why boss order matters
The six bosses are a gate, not a list. Each one drops the item that opens the next biome, so the order is fixed by progression.
Skip a boss and you block yourself from the materials the next zone needs. Plan around the drop, not around the fight.
Eikthyr — Meadows
Eikthyr is the first wall. He charges and strikes with lightning, then closes for melee.
Bring a shield, a spear, and at least one cooked-meat food. Block his charge, dodge sideways, and stab on the openings.
His drop is the hard antler, which unlocks the pickaxe. You need it before you can mine tin, copper, or any rock.
The Elder — Black Forest
The Elder roots you from range and summons wisps, then slams in melee. Fire weakens him more than plain arrows.
Use the terrain: pillars and trees break his line of sight and give you windows to shoot. Burning arrows or a torch-fueled weapon do the work.
He drops the swamp key. That key is your only way into the Swamp, where Bonemass waits.
Bonemass — Swamp
Bonemass is slow and poison-heavy, and he spawns blobs to swarm you. Plain physical hits barely scratch him.
Drink poison resist mead before you enter. Bring fire and a sturdy shield, then kite him in a wide circle while you burn him down.
He drops the wishbone, which finds buried metal and the entrails you need for later upgrades.
Moder — Mountains
Moder is a frost dragon. She breathes ice, summons wolves and drakes, and tears the ground when she lands.
Frost resist mead keeps you standing through her breath. Use rocks for cover and answer her with fire, which she takes extra damage from.
She drops scales for padded armour, the set that finally lets you ignore the cold.
Yagluth — Plains
Yagluth is a burning colossus. He throws fire and magic from range and summons adds to split your focus.
Fire resist mead is mandatory here. Pillar-kite him, clear the summons first, and keep your bow ready for the moments he plants himself.
He drops the materials for the final forge upgrades, and the last step before the Mistlands.
The Queen — Mistlands
The Queen summons ticks and presses in melee. The Mistlands gear you arrive in decides whether the fight is fair.
Bring both frost and poison resist, clear her adds before they pile up, and use the openings between her summons to land heavy hits.
Her drop feeds the late-game crafting tree, which closes the loop the first five bosses opened.
Build before you fight
Every boss is easier with the right tier of gear. The weapon progression guide shows what to carry into each biome.

Fader: the seventh boss, and the only one that can kill a fully geared player in four seconds
Fader is the Ashlands boss — a charred, skeletal dragon that glows green through the gaps in its body. Everything below is from his attack data, and the numbers are the reason he is the hardest fight in the game.
Summoning him
The summoning altar sits in a coliseum-like structure in the Ashlands. To find it, read the Vegvisir in the central tower of a Charred Fortress — it reveals the nearest altar on your map. Very occasionally one sits on top of Charred Ruins instead.
The ritual: place three Bells around the coliseum. Each Bell costs three Bell fragments, and the fragments come from Charred Fortresses around the Ashlands. That is nine fragments before you can pull him out.
Fissure — the attack that ends runs
Fader draws a line on the ground with his left paw, raises it, and slams it down.
- 12 to 16 circles of small green flame appear, each with an 11 meter radius, summoned 0.45 seconds apart over 5.4 to 7.2 seconds.
- After a 4 second delay (per circle), large spikes shoot up where the flame was, followed by a flame pool.
- The pool deals 120 Fire, 80 Spirit, 40 Tier 0 Chop and 40 Tier 0 Pickaxe damage.
- The flames last 15 seconds and cannot be dodged or blocked.
- Cooldown: every 30 seconds between 35% and 85% health, every 20 seconds under 35%.
- He can cast it when you are within 40 meters.
The wiki’s own note on this attack: it can kill a player even with full Flametal Armor and a Fire resistance barley wine active, in mere seconds. That is not a warning about gear. It is a statement that gear does not solve this attack — positioning does.
Because the circles are placed around players and the spikes land 4 seconds after the flame appears, the answer is to keep moving the moment the paw touches the ground, and to not commit to an attack animation during the sequence.
Bite and Claw — the close-range tax
| Attack | Reach | Damage | Cooldown |
|---|---|---|---|
| Bite | 10 m, 40° arc | 210 Pierce, 300 T3 Chop, 300 T3 Pickaxe | Every 3 s within 9 m |
| Claw (left) | 10 m, 65° arc | 200 Pierce, 300 T3 Chop, 300 T3 Pickaxe | Every 3 s within 9 m |
| Claw (right) | 10 m, 65° arc | 200 Pierce, 300 T3 Chop, 300 T3 Pickaxe | Every 3 s within 9 m |
Two claws means two separate 3-second cooldowns, so the melee pressure is roughly double what a single cooldown would suggest. Both hit a 10 meter arc, which is longer than most Valheim melee ranges — standing “just outside” his head is still inside the claw.
The practical read: melee DPS windows are short and must be timed against the claw that just fired, not against the one about to.
How to actually fight him
- Bring fire resistance and still treat fire as lethal. The barley wine buys seconds, not immunity.
- Watch the paw, not the health bar. The Fissure cast is telegraphed by the line-draw, and the 4 second spike delay is your whole window.
- Fight from range where you can. Bow and magic keep you outside the 10 meter bite/claw arcs, which removes two of his four attacks from the fight entirely.
- Do not stand in the flame pool to finish a combo. 15 seconds is longer than any melee rotation.
- Expect the cadence to tighten at 35%. Fissure drops from a 30 second cooldown to 20, which is the phase where most attempts fail.
