The Frostvault dungeon is located in the west of Eastmarch, the dungeon is part of the Wrathstone DLC. In the Frostvault dungeon you will encounter a total of five bosses and a few trashpacks. The first two bosses are fairly easy, but after that it gets more complicated. The last boss also has a hardmode which is a beast of its own, it is currently the most difficult hardmode in any of the four man dungeons.

Rewards & Loot




First Boss – Icestalker Troll Boss

Boss Health:[HP: 3,867 Mio]

This boss is fairly easy, all you have to make sure is to face the boss away from the group as a tank. He will stomp onto the ground and a conal stonewave will appear, if it goes into the group it will do a lot of damage but as a tank you can absorb the damage easily. The second attack which is a knock up will target a random group member, after the knock up you have to make sure to interrupt the boss, otherwise the player will get a crazy blow to his face and most likely die.

Second Boss – Warlord Tzogvin

Boss Health: [HP: 4,060 Mio]

This boss has a lot of AoE skills that you need to try to avoid. He also does use Wrecking Blow, for the tank not such a big deal but if another group member is targeted it will oneshot the player (you can dodgeroll the attack). He also has a whirlwind attack that does medium damage, you can ignore or block the damage. After a while he will summon his fire greatsword and leap into the air, once he comes back down all people that are close by will get knocked back. After the knockback, he will start casting flames on all group members, make sure not to stand close to each other, otherwise you overlap the fire damage and will die. The next weapon he is going to summon is the forst greataxe, once the axe is summoned frost whirlwinds will appear over the whole arena that you need to avoid.

Note: Sometimes you will see a notification “tethered”, this means two players have been tethered and need to walk away from each other to break the tether.

Third Boss – Vault Protector

Boss Health: [HP: 3,909 Mio]

Here it starts to get really tricky, this boss kind of reminds me of the laser room in Resident Evil. In addition to the Vault Protector boss, there is a lot of adds that spawn. Make sure to kill them as fast as possible, because if the small spiders will stay alive for too long they will turn into a charging module for the Dwemer Spheres and they will deal increased damage. If you kill the small spiders be careful, they will detonate after they die.

The boss itself is not really dangerous, he has a few attacks but as long as the boss stays on the tank it should not cause problems. The challenge here comes in dealing with the laser beams. After you damage the boss a bit, he will turn into a ice cube and lasers will appear. Now you have to take a look on which side the laser beam is getting powered, once you know that you have to go to the other side of the ice cube to avoid the laser beam damage. The laster beam damage pretty much oneshot everything, so it must be avoided at all cost. At the start there is only one laser beam, but the closer the boss gets to death, the more beams will show up. There will also be blue balls rolling around, you can just ignore them, if you run into them they will stun you.

Tip: Wait till the boss is in one of his mechanics, then try to burst him down as fast as possible, otherwise he will keep going into the icecube mode.

Fourth Boss – Rizzuk Bonechill

Boss Health: [HP: 5,702 Mio]

There is a lot of AoE damage in this fight, make sure to avoid all the AoE damage or block it if necessary. Rizzuk will cast a frost blast after a while, infecting everyone with some sort of curse. After a few seconds you will get frozen and explode in a certain area. Make sure that all group members are split, if you overlap this aoe damage with two people because you are too close together you will die. From time to time there will also be a spiked iceball rolling around. Make sure to block the damage if it comes close to you and explodes, it does medium damage if blocked. There is also big icestorm aoe fields in the arena, they will oneshot you but are easy avoidable as they are just static. The boss will also start channeling frost bolts, you have to interrupt this, otherwise it will deal an insane amount of damage to random group members.

Final Boss – The Stonekeeper

Boss Health: [HP: 4,233 Mio]

This boss has a lot of mechanics. As a tank you have to deal with a huge healing debuff on you. On top of that he also shoots laser beams and a fire cone at the tank, you will need a lot of health and healing to survive. You can once again find roaming blue balls rolling around, if you walk into them they will stun you and deal medium damage. The boss has two arms that you need to focus on first before you even can damage the boss. His right arm has a blade attached to it, make sure to stay out of the AoE range, otherwise you will get a lot of damage. After the arm is broken, a Dwarven Centurion will spawn, kill him as fast as possible.

  • Right Arm: Rotary Blades Gauntlet
  • Left Arm: Flame Bellows Gauntlet

After both arms are defeated, you can start damaging the boss till he reaches 70% health. From a 100% to 70% you will have to be careful, he will now start to rotate and spit fire out of his sides where the arms were. If you get it by the fire you are instantly dead.

Once you reach 70%, you have to go to one of the green glowing beams and transform into a Skeevaton. Once all four players are downstairs, you will need a lot of teamplay to go through this. First off charge up your ultimate in the middle by pressing the first skill. After that you can split in a group of two and follow the blue lines. The blue lines will lead you to a Shock Conveyor that you need to disable with your Ultimate. Once that happened, go back to the middle, recharge your ultimate and rinse and repeat. The difficult thing here is, that there is traps like Fire Blasters and rotating blades that can kill you. So make sure to make use of your speedbuff and heal!

After you deactivated four Shock Conveyors you will get teleported back up, the boss has his arms again! Now same thing happens as before, kill the arms and drop the boss. The only thing that is different now is that there will be random rotating blades that circle the room. If you dodgeroll or shield them, you will take no damage but keep in mind they also apply a bleed on you if you do not avoid them. At 30% you will have to go back to Skeevatown and solve the puzzle again.

From 30% to 0% you will have all the mechanics from before, but now the boss will also do steambreaths out of his arms to protect him. The damage basically oneshots, so you want to make sure to not stand on the side anymore, but rather closer to the back, just keep in mind that you do not forget to heal the tank.

Final Boss Hardmode

Boss Health: [HP: 7,620 Mio]

I hope you brought your savety belt and maybe a secondary mouse and keyboard in case you break your first one. This hardmode is the thoughest so far out of all the hardmodes we have seen. Most people get stuck at the skeevaton mace, lets start there.

This was the most efficient tactic we could find. Number 1 and two we go all four together and number 3 and 4 we split into two groups. That way when you split into two groups you do not have to go back anymore, so you have less chance of actually ending up dead.

  • 1: All 4 together
  • 2: All 4 together
  • 3: Tank & DD
  • 4: Healer & DD
