Raid: Shadow Legends Doom Tower guide: floors, keys, bosses and Secret Rooms

The Doom Tower opens at account level 40 (HellHades and InTeleria agree on this) and sits in the Game Modes menu next to Faction Wars, Arena and the Clan Bosses. It rewards consistency more than power: a player who spends both key types every day gets far more out of a rotation than a stronger player who logs in twice a week. If you have not set up your dungeon farming yet, read the dungeons guide first; the overview of every mode is on the Raid: Shadow Legends hub.

Floors and difficulties: the real numbers

Doom Tower counts are a mess across the web. You will see 120 floors, 132 stages and "over 200 floors" in different guides. Plarium's official game overview settles it: you can climb 120 floors on both Normal and Hard, with a boss on every tenth floor. Every other count is the same tower counted differently:

Both difficulties are open at the same time, and keys work on either. Each floor has to be beaten in order. Regular floors pay completion rewards once per rotation; boss floors can be farmed again and again after the first clear. Plarium's forum guide also notes that players are ranked by how many turns they need to clear all floors and Secret Rooms, with separate Global and Clan rankings, and you enter the rankings after clearing Floor 10.

How Doom Tower Works: Keys, Floors, and Core Mechanics Guide

Gold Keys and Silver Keys

Everything in the tower costs a key, and there are two kinds. Plarium's descriptions of both:

• Gold Keys open a floor you have not cleared yet, including the first clear of a boss floor. You get 10 per day. The official overview is explicit: you cannot get more, and they reset every day, so unused Gold Keys are simply lost.
• Silver Keys open Secret Rooms and let you re-enter cleared boss floors to farm Forge materials. You also get 10 per day.

Plarium's guide adds two details that change how you play. A failed Secret Room attempt does not consume the key, so there is no penalty for trying. And daily reset is at 00:00 UTC, so plan your last climb of the day around that time, not your local midnight.

Bosses and the Forge sets they unlock

Boss floors are the reason endgame players climb. After the first clear, Silver Keys let you farm the boss for a unique Forge material, and Plarium states that the Doom Tower sets can only be crafted with materials earned in the tower. The official overview says the tower has three rotations, each with four bosses to overcome, so the boss list changes from one month to the next. Plarium's guide names these bosses and materials; the set pairings below are the ones confirmed by at least two current guides (HellHades, BlueStacks, ayumilove). Bommal's set is left out because the sources disagree:

Each boss has a gimmick. Bommal summons Dreadbombs that explode for pure damage, and Astranyx creates mirror copies of your own champions. Plarium's Visix guide recommends her Provoke against Kuldath and her Turn Meter reduction against Astranyx. Update 10.90 also made bosses immune to Ensnare, Fatigue and Hunter's Gaze, so do not plan around those debuffs. To see what a boss drops in the current rotation, open Reward Info on the tower map after the first clear.

Which set to farm is a question for the artifact sets guide. In short, HellHades rates Lethal among the best Doom Tower sets and Affinitybreaker as one of the weakest, so spend your Silver Keys accordingly.

Secret Rooms: rules and champion fragments

Each difficulty has 12 Secret Rooms. They unlock one by one as you climb and can then be cleared in any order. Every room has a team rule, and Plarium's examples are "only using Rare Champions" and "only using Skinwalkers". Other rooms lock you to a faction, an affinity or a champion type, and the rules change with every rotation.

Room rewards are paid once per rotation. The main prize is champion fragments: collect enough fragments of a Doom Tower champion and you can summon them from the Fragment Summon tab. Plarium's guide lists a fixed order of champions, starting with Archmage Hellmut on Normal and Thea the Tomb Angel on Hard. Once you have collected every fragment on a difficulty, its Secret Rooms drop boss Forge materials instead.

Secret Rooms are why a deep roster pays off. Plarium's own guides point at exactly this kind of champion:

Warmaiden is another official example: Plarium recommends her for Force affinity Secret Rooms. When you build Rares and Epics, keep a few from different factions and affinities. Our Rare and Epic champions guide covers which ones are worth the investment.

Rotations and rewards

The tower runs in rotations of about a month. Plarium's guide describes a 30 day cycle: when it ends, the tower resets, a new rotation opens with different bosses, floor enemies and Secret Room rules, and you climb again for a fresh set of rewards. Secret Rooms you unlocked stay open for the rest of that rotation, but after a reset you have to climb to them again.

Three reward streams come out of every rotation: floor completion rewards (once per rotation, with shards among the bigger ones according to community guides), champion fragments from Secret Rooms, and Forge materials from farming bosses with Silver Keys. Missing a rotation means missing a share of all three, which is why the tower belongs on the daily list next to the Hydra and Chimera and the Clan Boss.

Plarium's official channel also has a video on the latest rotation and reward changes. Watch it for the current state before you plan your keys, since rotation details are the part of the tower that changes most often.

Teams for floors, bosses and rooms

The tower asks for three different kinds of team, and most players fail because they try to use one team for all of it.

• Wave team for regular floors. Floors are fights against waves of enemies, so AoE damage, crowd control and sustain matter more than single target burst. Plarium's guides point at the same profile again and again: Geomancer clears waves with his AoE and punishes high HP enemies, and Stag Knight is called an excellent choice for clearing rooms because the tower is mostly wave based PvE. This is also the team you leave on Auto-Climb, so pick champions that win on Auto without manual skill timing.
• Boss team per boss. Each boss needs its own answer. Kuldath wants a Provoke, Astranyx wants Turn Meter control, and Bommal punishes teams that cannot deal with Dreadbombs. Build these teams one at a time, starting with the boss whose set you want most, and save them as presets so you do not rebuild them every rotation.
• Restricted teams for Secret Rooms. These depend entirely on the rotation's rules. A deep bench of geared Rares and Epics from many factions is the only real preparation.

Accuracy is the stat that quietly decides all three. Plarium's Coldheart guide notes that she needs relatively little Accuracy for farmable dungeons but significantly more for the Doom Tower and other high Resistance encounters. If debuffs keep getting resisted on the higher floors, raise Accuracy before you look for more damage.

A daily routine that gets the most from a rotation

1. Right after 00:00 UTC, start Background Auto-Climb with your wave team so the 10 Gold Keys get used while you play other modes.
2. At a boss floor, swap to that boss's preset and spend a Gold Key on the first clear yourself.
3. Spend Silver Keys on any unlocked Secret Room you can win first, since fragments are paid once per rotation and a failed attempt costs nothing.
4. Put leftover Silver Keys into boss farming for the Forge material you actually plan to craft with.
5. Check the reset timer on the Game Modes tile in the last week of a rotation, and prioritize unfinished Secret Rooms over boss farming before the tower resets.

Background Auto-Climb (Update 11.50)

The biggest Doom Tower change of 2026 came in Update 11.50 (May 2026): Background Auto-Climb. Once you activate it, your team climbs floor by floor in the background on Auto while you play other modes. Plarium's rules:

1. Regular floors only. It does not include Boss Floors or Secret Rooms. Those you still play manually.
2. It stops on its own when your team is defeated, you run out of keys, or it reaches a Boss Floor.
3. Rewards are all shown. Since Update 11.80 (October 2026) the reward window lists everything earned in an Auto-Climb, not only 10 unique rewards.

In practice: set a sturdy wave clearing team on Auto-Climb at reset, let it spend the Gold Keys while you farm dungeons, and step in yourself at each boss floor. Update 11.80 also fixed a bug that could make Background Auto-Climb unavailable after a lost internet connection.
