Doom Tower Overview

  • Doom Tower is a new game mode released on December 7 2020, which feature 132 stages (108 Common Floors, 12 Boss Floors, 12 Secret Rooms) for you to fight through.
  • It will be available in Normal and Hard difficulties, both of which will be repeatable
  • The Doom Tower resets every 30 days, erasing your progress, Rankings, and rotating some of the Bosses.
  • Golden Keys will be required to access a Floor for the first time, while Silver Keys will let you access Secret Rooms or replay Boss Floors you have previously completed.
  • In both cases, the Key will only be subtracted from your total if you successfully complete the Floor or Secret Room.
  • Neither Golden nor Silver Keys can be purchased. There is a limit of 10 Keys on both, and it resets at 00:00 UTC every day.
  • However, if you receive these Keys as a reward for in-game activity, they will be available for you to use before the next reset.
  • Doom Tower Floors follow a classic scheme: your Champions fight through 3 Rounds of enemies, while every 10th floor will feature a Boss fight. These Bosses will be different and their power will scale with the difficulty you’ve chosen and your progress (the Boss on Floor 110 will be much tougher than the Boss on Floor 10).
  • Secret Rooms will pose an additional challenge as they require specific conditions to complete. Such as using Champions of a specific Rarity, Faction, or Type.
  • Completing a Floor for the first time will earn you a set reward that cannot be farmed again before the Doom Tower is reset.

Doom Tower Storyline

Many millenia have I shielded the realm of Teleria from Darkness. Countless foes rose to challenge the will of the Goddess, some were slain but there are creatures of eldrich might that could only be banished from the world. Those I had imprisoned in a tower of obsidian and magic, there to be forever trapped in a cycle of their own malice. But the tide has turned. My strength wanes while Siroth and his minions grow in power. I fear we can no longer trust the ancient wards to hold the tide of evil at bay. That is why I ask you, my Champions, to accept this sacred duty. Venture forth and face the creatures of doom that lurk within the Tower. Perhaps together you shall achieve what I could not those many centuries ago… Make haste, I implore you, for the fate of Teleria hangs in the balance.

    Yes exactly, Drexthar is very good for frost spider, I was very lucky to get him otherwise I wouldn’t have made it through frost spider.

  2. alix one

    Another vote for Drexthar Bloodtwin as a MVP for Frost Spider. He sets the spider on fire when he’s hit, meaning that often the spider gets burned immediately after losing the last burn.

    Stag Knight’s increase ACC ability is clutch for Frost Spider too, because of the increased resist when not under a Hp burn, along with the reduce speed and defence down.

  3. Vokko

    Warchief is godlike for Magma Dragon. After he was nerfed over a year go, he finally has a use in the game besides Vault Guardian.

  4. Teacup

    for frosty spider hard lvl 70+ you need very high ACC to put hp burn on him, my Tyrant had 330ACC was unable to land a single hp burn on it, upgraded to 336, was able to land 1 in about 5, I need to farm a 96ACC banner now, currently using 78ACC

  5. Mr. Nuffle

    Not a time limit, but a turn limit off 1000 turns.

  6. daniel

    Metalshaper should 100% be added to the Borgoth MVP list. He is quite possibly the best champion in the game for this in terms of accessibility and being easy to build (just high speed and survivability).

  7. ymirsson

    Kuldath the Magma Dragon also is immune to turn meter reduction

  8. dhillers

    Thaniks for the info, as always. Please examine your recoomendations for Scarab King the play is is better handed by advice i saw on Hell Hades page… I went to a team of Duchess Lillitu, Ithos, Valkerie, Coldheart, and Madame Serris after a few tries with other Chars, and went from 9 minute fails to 3 minutes and out.

  9. Robius


    A full booked Sir Nik can easily solo Borgoth floor 100 IF the team built around him was able (before to die) to lower Borg max HP at least even under 10%.

    My Sir Nik had these specs: 80k hp, 2 Immortal sets 1 Speed set, 220 resist (mandatory, to get almost no provoke or steal C-Heal).

  10. Gulyabani

    Rotos is not MVP for Borgoth because his skill does not work on the bosses.

    By the way, is there a time limit for stages? I tried the top floor twice on Normal, game freezes when the spider dies.

  11. GuacamoleBen

    Ayumilove, your site is great. Possibly add Metalshaper to the list of good champs for Borgoth?

  12. Ayumilove Post author

    @Knightmayre: I have updated the Doom Tower Hard Secret Room requirements based on your input. Thanks!

  13. Knightmayre

    @ayumilove thanks as always for all you do!

    My clanmates have me a couple of corrections for secret rooms –

    Hard SR4 is Epic Lizardmen, not just Lizardmen.
    Hard SR7 is Support champs

  14. Knightmayre

    @sir – only “all battle” auras for now. They’ve said they will add DT-only auras :/

  15. HW3

    I am confused by Borgoth’s ‘spectral horror’; a) is ‘max hp reduced’ referring to actual max hp reduction or just damage taken? and b) all of the categories of hp reduction given (<10%, 10%-20%, 20%-30%) are less than 30% but I imagine 0% reduction of damage taken does not always apply. Can you clarify this?

  16. HW3

    Man, the dwarf secret room really point out (if the faction wars hadn’t already) how lame my dwarves are.

  17. Emalkartha

    Doom Tower convinced me to quit Raid.

  18. WileyMan

    @Beze: Ultimate Galek self-buffs the ATK Up and he has a 50% chance on all of his skills. A fully-booked Wyvernbane does a 2-turn HP Burn on a 4-turn cooldown. There is no comparison. Ultimate Galek wipes the floor with Wyvernbane if you are looking for HP Burn uptime.

    If you want a Rare option, Bulwark is probably your best bet: fully-booked, he does a 2-turn HP Burn on a 3-turn cooldown.

  19. MrShovel

    For borgoth, why is rotos not listed as mvp, as he has a 2 turn 20% hp decrease.

  20. Sir Screeli

    Perhaps I overlooked it, but what aura skills will apply in the Doom Tower, if any?

  21. Hawkmistress

    Me thinks this new thingy (doom tower) will put a new twist on masteries.

  22. Beze

    For Sorath, put Wyvernbane on the MVP list here.
    Ultimate Galek is a nightmare to handle, because his LP-Burn only activates when a ATK-Buff is active (so you need Spirithost or Warpriest or something like that around as well – and Sorath throws dispel around every 3 turns) and also has only a 50% chance to do so. Took me approx. 30 tries to finally beat the Boss.
    Wyvernbane, however, can easily be booked to 100% chance, is an easily obtainable rare, and all around just so much more fun to use at Sorath.

  23. Morhen

    Hey folks,

    Do any of the “Leader” Auras activate in the Doom Tower? Other than “All Battles”.

  24. Dark Elhain

    My team for Frost Spider:
    Miscreated Monster in Stun set + Harvest Despair mastery for Leech
    Scyl in Stun set + Harvest Despair mastery for Leech
    Drexthar (no masteries yet)

  25. pOPETOOS

    For the frost spider, other MVPs.
    – Teela Goremane: HP burn and leech, plus steals buffs.
    – Drexthat Bloodtwin: HP burn everytime he is attacked, and in all his skills.
    – Dark Elhain: attacks whenever an ally gets freeze.

  26. pOPETOOS

    For the Scarab King, Vergumkaar should be the MVP.
    Does shields and increase defense. This pairs well with an Armiger in destroy set. Removes buffs from the enemy can could place decrease defense.
    More importantly, is immune to Provoke, and can remove the provoke in other allies. This would be key for higher level bosses.
    It is also Spirit afinity!

  27. Agent9x0

    My Team with 3m5s on Hard mode for Borgoth was:

    Little Miss Annie – Decrease Enemy Max HP / Damage
    Siphi – Speed,Heals and Revive
    Arbi – TM, Attack Boost and Revive
    Madame – Shields herself, Dec Def, Dec Attack
    Miscreated – Shield set and Allied protection

    I would significantly improve on that by swapping miscreated with Zelotah but I don’t have him leveled.

    Zelotah and Hope are brilliant epics for this fight. They both have AOE ally shields based on their MAX HP and as such can consistently put up decent sized shields. Draconis is a rare option also.

    Don’t underestimate how useful destroy sets will be here as well 🙂

  28. Picachu

    Jizoh was my solution for Borgoth the Scarab King Boss; not very fast one but after he remain last standing he did excellent job .
    He had like 30% HP when rest of my team died and boss like 35-40%. When he finished the boss was having full HP 🙂

  29. Dark Elhain

    Miscreated Monster’s Shield is not so good.

    My team was :
    Drokgul – for Shield, heal counterattack and buffs
    Warlord – for Shield, heal
    Reliquary Tender – for heal and revive
    Ripper (4*, at lvl 16 , equipped with Destroy set) – for Decrease Enemy MAX HP
    Dark Elhain – for Decrease Enemy MAX HP

    Completed in 7m, but the time can be improved


    Valla is also a good champ for Borgath. I didnt have a badass Valarie or any of the MVP’s so i threw my 6 starred Valla in and she pretty much soloed the boss on Normal

  31. Hamid

    Miscreated monster and sir Nik are not that great for Scarab King, because their shield is based on how much damage they can deal, and Scarab King has a lot of defense. On the other hand their ally protection can be stolen easily along with block debuff of Duchess. That is why the only reliable shield hero for Scarab King is Draconis and Valkyrie. Actually, I don’t have Valkyrie and I don’t know if her Counterattack can be stolen.

  32. Decoverto

    Setthalia is not so good for Kuldath. She removes hex but then hex is going to be placed on herself, moreover she is placing HP burn that automatically is replaced by 15% continuous-heal on the boss for 2 turns. She is not only un-useful, she is damaging the team. Better to use another healer

  33. Ayumilove Post author

    @chuck chang: I corrected the typo in the Doom Tower storyline. Thanks!

  34. chuck chang

    “Countless foes rose ot challenge” should be “to” in Storyline

  35. DudeJB

    Opened Today December 7th 2020

  36. Ayumilove Post author

    @Armadaeus: I have fixed the mispelled champion name. Thanks for highlighting it!

  37. Armadaeus

    Just thought I’d let you know @Ayumilove you have Duchess Lilith spelled Dushess under Bargoth the Scarab King

  38. Ayumilove Post author

    @William: Plarium mentioned that they will open Doom Tower early mid December 2020. Hence, we should get prepared with the necessary champions to complete those Secret Rooms 🙂

  39. William

    When does the tower open up or how do you open it
