Diablo IV: How to Solve Rathma’s Puzzle in A Blade’s Weight

Rathma’s puzzle is one of those Diablo IV quest gates that looks more elaborate than it really is. During A Blade’s Weight in the Archive of the Makers, the solution is to read the Time-Worn Inscription and activate the skull altars in this exact order: Dunaxys, then Abythos, then Coruphar. That matches the inscription phrase “Power born of Hell begets Corruption.” In other words: Power = Dunaxys, Hell = Abythos, Corruption = Coruphar.

If you are following Diablo IV: Season of Infernal Chaos walkthroughs and Quests, the useful part is that current guides all point to the same altar sequence, and nothing in recent coverage suggests this puzzle was changed for the season. The room still works as a language-matching puzzle, not a combat trigger or random interaction test.

The exact Rathma puzzle solution

• Read the Time-Worn Inscription: “Power born of Hell begets Corruption.”
• Identify the altar names that match those words.
• Activate them in this order:
  • Dunaxys = Power
  • Abythos = Hell
  • Coruphar = Corruption
• After the correct sequence, the hidden wall opens and you can continue.

That is the whole answer, but the reason players lose time here is the room design. The Rathmic Statue sits in the middle, multiple altars surround it, and the game does not spell out that the words on the wall are the real key. If you try to solve it by symbols, statue direction, or by clicking every skull until something happens, it feels much more obscure than it actually is.

Where the clue is and how to read the room

In the Archive of the Makers, look around the central Rathmic Statue for the nearby inscription rather than staring only at the altars. The important clue is the sentence on the wall, and the important mechanic is translation. You are not being asked to guess a ritual. You are being asked to match specific words from the inscription to specific altar names.

The three names you care about are Dunaxys, Abythos, and Coruphar. When players get stuck, it is usually because they remember the sentence but do not connect it to the translated altar names, or because they second-guess the order and assume the phrase is thematic rather than literal. Here, the sentence order is the input order.

Why the puzzle trips people up

• The room has more visual noise than the actual puzzle needs.
• The altar names are lore-heavy, so they do not look like obvious answers at first glance.
• Diablo IV presents it like an ancient ritual, but mechanically it is just a word-matching sequence.
• Some players assume they need to clear enemies or interact with the statue first. You do not.

Step-by-step: solving the Rathma puzzle without guessing

If you want the clean version of the process, do it this way:

• Approach the puzzle room in the Archive of the Makers during A Blade’s Weight.
• Read the Time-Worn Inscription fully before touching the altars.
• Match the capitalized idea words from the inscription to the altar translations:
  • Power → Dunaxys
  • Hell → Abythos
  • Corruption → Coruphar
• Interact with those skull altars in the same order the words appear in the sentence.
• Watch for the hidden wall to open, then head through the newly revealed passage.

Important: do not overcomplicate the placement of the altars around the room. The puzzle is about the sequence of meanings, not left-to-right position, front-to-back symmetry, or any statue-facing pattern.

What to do right after the wall opens

Once the sequence is correct, the hidden path opens and the quest continues deeper into the area. This is where some walkthroughs stop, but if you are using this as a full Quests fix during Diablo IV: Season of Infernal Chaos, the next section matters because the pace changes from puzzle-solving back into combat progression.

Move through the newly opened route, clear the enemies in your way, and interact with the Scrawled Notes when prompted. After that, you will reach the Chamber of the Golem, where the quest shifts again. Instead of another word puzzle, you now need to restore progress by lighting the braziers tied to Rathma’s essence.

Chamber of the Golem basics

• Advance until you can interact with the chamber elements and speak to the relevant quest NPCs.
• Light the three Flame of Rathma’s Essence braziers to unlock the next doors.
• When the Pale Halls section opens, you will escort the returning Memories back to the chamber.

This part is straightforward once you know what the game expects: stay focused on the objective circle and kill blockers quickly. The chamber sequence is more likely to waste time through positioning mistakes than through lack of damage.

The easy-to-miss escort mechanic after the puzzle

After speaking to the chamber statue and Lorath, the quest sends you into the next area to retrieve the Memories. You escort each flame-like Memory back while fighting enemies, including tougher blockers such as Wymund Devourer. The piece that is easiest to miss is your position relative to the chamber.

Stay inside the central circle when required. If you drift too far or chase enemies out of the objective space, it can look like the Memory has stalled or the quest is not advancing. This is one of those Diablo IV moments where killing faster does not solve the problem if you are standing in the wrong place.

So the safest approach is to fight close, clear anything body-blocking the path, then re-center immediately. If you play a mobile build, this is especially worth remembering because dashing after stragglers can slow the objective more than it helps.

Rathma’s Golem boss: the phase that looks broken but is scripted

After restoring the Memories and surviving the enemy waves, you interact with the cracked statue to begin the Rathma’s Golem fight. Most of the encounter is a normal boss burn, but near the end the fight changes in a way that often confuses players: at low health, the golem becomes effectively unkillable for a moment and rips out your spirit.

That soul-rip phase is part of the encounter. You become a wisp-like form with movement advantages, and your job is to get back to your body quickly so the fight can resume. If you suddenly stop dealing meaningful damage at the end, do not assume your build is failing the DPS check. The phase transition is supposed to happen.

If Rathma’s Golem stays invulnerable

There is, that said, a separate issue reported by multiple players: after the soul-return phase, the boss can remain non-targetable or invulnerable and the quest stalls. This does not appear to be the intended scripted behavior.

The most common workaround reported by players is to dismiss your mercenary and retry the encounter solo. On PC, you can open the mercenary panel with Shift + M. The theory from player reports is that mercenary interactions may interfere with the phase transition. That is not an official fix, but it is the most practical workaround if the boss refuses to become vulnerable again.

Common mistakes that make the puzzle feel harder

• Reading the clue but not using the names: the solution is not “Power, Hell, Corruption” as raw concepts; it is the altar names tied to those concepts.
• Ignoring the sentence order: the order is exactly as written in the inscription.
• Trying to solve by room layout: altar position is less important than the translated meaning.
• Leaving the chamber circle during the escort: this makes post-puzzle progress look bugged.
• Confusing the scripted soul phase with a broken boss: only treat it as a bug if the golem stays untargetable after you return.

Practical wrap-up

For A Blade’s Weight, the part you need to remember is simple: read the inscription, then activate Dunaxys → Abythos → Coruphar. Once the wall opens, the real time-saver is knowing that the next bottlenecks are positioning in the chamber and the late Rathma’s Golem phase. If the boss genuinely locks up, dismiss the mercenary and retry before wasting more time on a broken run. That keeps this Diablo IV: Season of Infernal Chaos quest moving instead of turning one small puzzle into a full progression stop.
