🗼 Doom Tower
The 120-floor tower — keys, rotations, every boss and its counter, Secret Rooms, and how to clear waves vs bosses on a mid-game account.
🗼 Contents
Overview
Doom Tower is a recurring PvE climb: 120 floors (108 wave floors + a boss floor every 10th floor = 12 boss floors), plus optional Secret Rooms. It rewards forge materials, exclusive champion fragments, shards, silver, XP brews and energy. It runs in 30-day rotations — at each reset the bosses, floor enemies, and Secret Room rules change.
Doom Tower uses keys, not energy
You get 10 Gold Keys + 10 Silver Keys per day (reset 00:00 UTC), shared across Normal and Hard. Gold Keys clear a floor for the first time. Silver Keys re-farm cleared boss floors and enter Secret Rooms. Keys are consumed only on a successful clear — so you can retry a Secret Room as many times as you like until you win.
Normal vs Hard run simultaneously — both are open and progressed independently. Hard is much tougher and gives Legendary fragments + 5–6★ artifact materials; Normal gives Epic fragments. There’s no “floor X unlocks Hard” gate.
Boss Rotations
Three rotations cycle the eight bosses:
| Rotation | Bosses |
|---|---|
| 1 | Magma Dragon · Scarab King · Nether Spider · Frost Spider |
| 2 | Magma Dragon · Celestial Griffin · Nether Spider · Eternal Dragon |
| 3 | Bommal (Dreadhorn) · Scarab King · Celestial Griffin · Dark Fae |
The Bosses & Their Counters
| Boss | Core mechanic | Counter |
|---|---|---|
| Kuldath the Magma Dragon | Applies Hex and hammers the Hexed target, ignoring defensive buffs | Provoke to control his big hits + survivability; Decrease ATK |
| Sorath the Frost Spider | Passive revive + 2 spiderlings that cleanse/buff her; A3 strips buffs & Freezes | HP Burn (beats the revive) or Block Revive; high ACC; kill spiderlings |
| Agreth the Nether Spider | Stacks heavy Poisons, then force-detonates them for huge team damage | Cleanse (poisons are irresistible), shields/block-debuff, a reviver |
| Borgoth the Scarab King | Negates ~90% damage until his MAX HP hits ~60%; counters unshielded hits | Destroy MAX HP effects; keep shields up to avoid counters |
| Grythion the Celestial Griffin | Stacks Sky Bond → ignores shields, Block Damage and Unkillable | Fast, high-burst team (race the stacks); turn-meter control |
| Iragoth the Eternal Dragon | Can lock out your abilities (A1-only) and punishes cooldown use | High RES to resist the lockout; lean on basic attacks |
| Astranyx the Dark Fae | Summons mirror copies of your own champions | AoE + Decrease DEF to kill clones; turn-meter control |
| Bommal the Dreadhorn | Dreadbombs — see below | Freeze the bombs + sustain; HP Burn |
There is no boss called 'Sorath the Anointed'
“Sorath” is the Frost Spider. Don’t confuse it with the unrelated Rare champion “Anointed.” The Doom Tower roster is the eight bosses above — the top of the tower is simply a boss floor from the active rotation.
Bommal the Dreadhorn (detail)
One of the hardest DT bosses, and the one Lady Annabelle is built to solo.
- Dreadbombs are unkillable minion-bombs. Bommal summons two with his big attack, and his passive summons one every time his Turn Meter is decreased — up to 6 at once.
- When a Dreadbomb pops it deals 40% of its own MAX HP to your whole team (ignoring shields), reduced to 20% if the bomb is Frozen.
- Bomb debuffs placed on your champs cannot be blocked, resisted or removed and detonate after 2 turns.
Two things that DON'T work on Bommal
Don’t decrease his Turn Meter — it spawns extra bombs. And Decrease ACC does not stop the bombs (they’re unresistable). The real answers are Freeze (halves bomb damage), HP Burn (one of the few things that affects bombs), and raw sustain.
Strong picks: Vogoth, Drexthar Bloodtwin (passive HP Burn), Master Butcher / Lady Annabelle (heal off enemy/bomb deaths on Immortal + Regeneration), and Templar / Crimson Helm as budget solos via timed Block Damage. Hard mode needs ~330 ACC to land debuffs reliably.
Astranyx the Dark Fae (detail)
The floor-120 boss on rotation 3, and a common wall — she summons mirror copies of your champions (same stats, sets, auras and blessings) and layers Fear.
- Immune to [Stun], [Freeze], [Sleep], [Provoke], [Block Active/Passive Skills], [Fear] and [True Fear], plus HP-exchange, HP-balance and cooldown-increase effects. Turn-Meter reduction against her is halved.
- What still works: [Decrease SPD], [Decrease DEF], [Decrease ATK], [Heal Reduction], [Leech] — plus AoE + Decrease DEF to delete the clones fast and turn-meter control to deny her turns. Bring Fear cleansing/resistance (Doompriest, Inquisitor Shamael).
- She is Void affinity, so no champion gets a strong-affinity hit/accuracy bonus against her — you must bring the raw ACC. A fast Decrease SPD support like Stag Knight is on-strategy here, but only if its ACC clears the bar below.
Accuracy & Resistance — why your debuffs get resisted
Landing a debuff is a two-step roll: first the skill’s own listed chance (e.g. “30% chance per hit”), and then an Accuracy-vs-Resistance check. Two rules always hold:
There's a 3% resist floor — and Hard DT bosses want ~330 ACC
No amount of Accuracy guarantees a debuff lands — there is a permanent ~3% resist floor. To get into the reliable ~95%+ range you generally need to be ~25+ ACC above the target’s effective Resistance. On Doom Tower Hard that means ~330 ACC (Normal is ~100). So a 292-ACC champion on a Hard floor-120 boss isn’t unlucky against the 3% floor — it’s genuinely under the line and will be resisted regularly. Fix it by reaching 330+ ACC (Accuracy set, ACC banner/chest, glyphs), or bring an Increase ACC buff / ACC aura, which roughly halves the requirement.
Secret Rooms
Optional challenge rooms with team-composition restrictions (a required faction, affinity, rarity or role). 24 per rotation: 12 Normal + 12 Hard, unlocking as you climb. Enter with a Silver Key (consumed only on success).
Secret Rooms grow your key pool
First clear gives 3 exclusive champion fragments + 2 Silver Keys back — a net +1 key. Normal → Epic fragments, Hard → Legendary fragments. These build Doom-Tower-exclusive champions (e.g. Epic: Akoth, Rian; Legendary: Thea the Tomb Angel, Gomlok, Urost) you can’t summon anywhere else. Once you’ve collected all of a difficulty’s fragments, the rewards convert to boss-forge materials.
Waves vs Bosses — Mid-Game Advice
- 1
Wave floors: AoE + control
108 of the 120 floors are 3-enemy waves. Bring 1–2 AoE nukers (a Decrease DEF champ like Warmaiden + an AoE hitter), plus a healer/shielder and ideally AoE crowd control (Stun/Freeze/Provoke) so a wave can't burst you. Match floor affinity where you can.
- 2
Boss floors: stack universal utility
Decrease ATK (blanket damage reduction), Decrease ACC (makes debuff-reliant bosses whiff — except Bommal), Freeze, Cleanse/Block Debuffs, and a reviver carry most boss fights. Then layer the boss-specific counter from the table above.
- 3
Match affinity to the boss
Most DT bosses are Void, so a Void-heavy team avoids weak hits and keeps crits reliable.
- 4
Farm cleared boss floors with Silver Keys
Once a boss floor is cleared with a Gold Key, re-run it with Silver Keys for its artifact set (Fatal, Untouchable, Affinity Breaker, Frostbite, Bloodthirst, Guardian, Fortitude, Lethal). Hard drops 5–6★ materials.
Champion Archetypes That Matter
| Archetype | Why | When |
|---|---|---|
| HP Burn applier | Beats Frost Spider’s revive; one of the few things that affects Bommal’s bombs | Frost Spider, Bommal |
| Block Revive | Alternative Frost Spider answer | Frost Spider |
| Cleanse / Block Debuffs | Survives Nether Spider’s irresistible poisons | Nether Spider |
| Destroy MAX HP | Pushes Scarab King through his 90%-mitigation phase | Scarab King |
| Provoke | Controls Magma Dragon’s heavy hits | Magma Dragon |
| Decrease ACC | Neuters debuff-reliant bosses (but NOT Bommal) | Magma Dragon, most bosses |
| Freeze + sustain tank | The Bommal package (halves bomb damage, out-heals it) | Bommal |
| AoE + Decrease DEF | Wave floors and Dark Fae clones | Waves, Dark Fae |
| High-burst / high-RES | Race Griffin’s Sky Bond; resist Eternal Dragon’s lockout | Griffin, Eternal Dragon |
| Reviver | Recovery on long boss fights | All bosses |
