Relic Dungeons is the mode where you will spend most of your Eternium because currently, it's the only place in the game where you can farm T7 Gear and T7 Materials that are used both in crafting new T7 gear and upgrading your current T6 gear to T7.

Alongside Dive 50, Relic Dungeons are the hardest content in the game and each of the three Dungeons has a set of restrictions that force you to use a certain composition to clear it.

Overall in this guide, I will only focus on analyzing the fourth stage of each Dungeon, because it has the best rates and gives the most materials. Also the teams I will show are tailored to work on auto-battle - the reason behind this is that you will farm the dungeons constantly and doing it on manual is pointless.

Drop rates

Each Dungeon consist of four stages and the drop rates seem to be the same no matter the Dungeon.

Each Dungeon has a debuff tied to it and basically it makes one type of employees unusable. Also, the debuff values vary between the stage number.

Weapon Dungeon

Relic Dungeon 1

In the final stage of this Dungeon you will fight Evil Titan and the unlucky employee type here are Soldiers. This dungeon drops only Weapons.

Fight mechanics

  • Evil Titan will cast a buff on himself from time to time, and if it isn't removed, it will become permanent, so you need at least one buff remover in your team,
  • his special skill deals stupid amounts of damage which means that healers that provide shields help you survive it,
  • while Evil Titan can remove all debuffs from self, debuffers are still good here - especially those who can constantly provide the debuffs, so even if they're removed, they will debuff him again,
  • employees that can stun Evil Titan help a lot, because it postpones his overtuned skill that can easily wipe your team.

Key employees

Regina MacCready
Awakened Hilde
Awakened Joo Shiyoon
Regina MacCready, Awakened Hilde and Awakened Shiyoon

Regina the main tank of the team that also acts as debuffer. Still, to make her work you need to have her at least 106 level, but 110 is preferred. Awakened Hilde and Awakened Shiyoon are a good alternative for the main tank's spot - Hilde keeps herself alive really well and Shiyoon with his perma-evasion buff also can survive quite a beating.

Yang Harim and Arius Esquede

While Evelyn provides pure healing, in this stage you need the barriers Yang and Arius bring to survive Evil Titan attacks. Still, Evelyn and Chinatsu are often used here too in addition to Yang/Arius duo.

Machine Collector and Yen Xing Lanchester

Both are here as buff removers, but MC is the better out of the two, because she can also debuff and stun the Titan.

Kestrel Xiao Lin
Replacer Queen
Rita Arsenico
Kestrel Xiao Lin, Replacer Queen and Rita Arsenico

The three core damage dealers that shine in this stage. Still, on top of doing great damage the trio brings, they can also stun the Evil Titan (and Rita acts as secondary debuffer).


If you don't have Replacer Queen, Ministra can act as the secondary damage dealer alongside Kestrel Xiao Lin. Overall in the recent few days Ministra became quite popular in this dungeon.

Key ships

Both Enterprise and Gleipnir: Armor type are commonly used.

Example teams

Titan Team 1
Titan Team 2
Titan Team 3
Titan Team 4

Armor Dungeon

Relic Dungeon 2

In the final stage of this Dungeon you will fight Evil Maria and the unlucky employee type here are Counters. This dungeon drops only Armors.

Fight mechanics

  • Evil Maria and other units will do less damage if the target has a barrier on. The problem is, Counter units are the debuffed type here, so you can't use Yang or Arius and you're forced to use Mechs that also can barrier themselves,
  • Evil Maria will use her special that hits whole battlefield every 10 seconds or so; targets without barrier will be basically one-shotted,
  • when you kill Jake, he will respawn after roughly 15 seconds. This gives you a short window to push toward Evil Maria's ship,
  • if you take too long, then enemy ship will push all your units back to your ship and often this leads to a wipe. You have roughly a minute to kill Maria and the ship before this happens.

Key employees

Horizon and Veronica

99% of the teams that cleared this stage on auto use Horizon. She's a Mech and her passive constantly gives her barriers, so she can not only ignore the stage mechanics, but also push toward the ship super easy. It's like the stage was designed with her in mind. The only alternative team that doesn't use her, has Veronica instead (check team number 3 screenshot below).

Awakened Horizon

Another mech that can self-barrier herself and she also acts as the damage dealer here - thanks to her %HP Damage.

Ifrit and Tarrasque

Both self-barrier themselves instantly on deploy and act as damage dealer and debuffer.


Thanks to his transformer passive, he gains a shield when his HP falls, making him a great choice for the Veronica team version.

Key ships

Coffin-6 works best here due to you mainly using Mechs, but New Detroit is good alternative, because A.Horizon/Ifrit are strikers. Still you need to adjust your deployment order a bit.

Example teams

Maria Team 1
Maria Team 2
Maria Team 3

Accessory Dungeon

Relic Dungeon

In the final stage of this Dungeon you will fight Evil Edel and the unlucky employee type here are Mechs. This dungeon drops only Accessories.

Compared to the previous two dungeons, a variety of teams work here and overall it's considered the easiest boss.

Fight mechanics

  • Evil Edel will constantly summon her monsters that will charge toward your ship,
  • in the 5 second of the battle, Evil Edel will use her special skill and attack the furthest unit with a large AOE attack. She will repeat the attack every 30 seconds or so. Most teams use a Tower employee to eat the attack; an alternative is to use Lake or Albion and save your units with shield, but on auto-battle this requires perfect timing.
  • Evil Edel's neck is stiff and she only looks at the ground in front of herself. That's why she will only user her ulimate skill if there are some ground units nearby (though the attack will hit any air units too if it's triggered). That's why Air units are better here.

Key employees


You need at least one Tower unit that will be auto-deployed at your ship and he will eat Edel's special attacks, saving your units.

Awakened Lee Sooyeon
Rosaria le Friede
Rita Arsenico
Air damage dealers

Basically if a unit is a flying counter, you can use it here.

Evelyn Keller

The only Air healer in the game is auto-included in most teams in this stage.

Awakened Joo Shiyoon
Awakened Na Yubin
Awakened Hilde
Awakened tanks and tanky frontliners

If you don't have enough Air units, using any two of the three above will be enough to tank Edel and her summonlings.

Key ships

Both Lake Superior and Albion work very well here.

Example teams

Edel Team 1
Edel Team 2
Edel Team 3
Edel Team 4
