QUICK ANSWER
Remember These First
Mektul is in the Molten Vault (Act 3), reached via the Sluice Gate / Aureadduct path. The fight has a hard lava-timer: the molten flow advances and you must defeat him before it overwhelms you.
Defeating him lets you deliver the Hammer of Kamasa and unlocks the Reforging Bench (a permanent system unlock). The lava advance is time-based and not paused by menus.

FAQ
Top search questions: entry, materials, failure cost
What is the Molten Vault entrance and how do I reach it?
Progress Act 3 to the Molten Vault via the Sluice Gate / Aureadduct path. The arena is the Molten Vault where the timed fight happens.
Is the advancing lava on a fixed timer, and is it affected by pause?
The lava advance is time-based and continues regardless of pause — leaving via menu does not stop it. Plan your flask/charm use before engaging; you cannot pause the timer.
How do I pull Mektul out when he gets caught in the molten flow?
When he is inside the molten flow, use your movement / a knockback or repositioning tool, or simply keep dealing damage and reposition so the fight stays at the arena edge. The key is not letting the flow pin both of you.
Which supports / skills can I swap temporarily, without a wrong generic config?
You may slot a single-target support temporarily for the DPS check, but do not build a generic 'one-size' config. Swap only what the fight demands (e.g., a damage support) and revert after.
How do I tell if it's low DPS, Mektul not pulled out, or wasted windows?
See the DPS Diagnosis table: check your effective DPS, whether he is stuck in lava, and whether you are using his recovery windows. Each has a distinct fix.
How do I deliver the Hammer of Kamasa and what does the Reforging Bench unlock?
On kill you obtain the Hammer of Kamasa (a quest item). Completing the step unlocks the Reforging Bench — a permanent crafting/system unlock for your account progression.

OVERVIEW
Timer Pressure
The Molten Vault fight is on a lava clock. The molten flow advances from one side and progressively fills the arena; if you are too slow, it pins you against the wall and you take continuous fire damage. The advance is time-based and is NOT paused by opening the menu — so you cannot buy time by pausing.
Your job: kill Mektul fast enough that the flow never boxes you in. Keep the fight at the open edge and use his recovery windows to burst.
- Lava advances on a fixed time, not by your actions.
- Menu pause does NOT stop the lava.
- Keep the fight at the open edge; don't get cornered.
OVERVIEW
Progression Unlock
Beating Mektul grants the Hammer of Kamasa and unlocks the Reforging Bench — a permanent system unlock in your campaign progression, not just a drop. This is the 'why it matters' beyond the fight itself.
The Reforging Bench persists for your account progression; treat the Mektul fight as the gate to that unlock.
- Hammer of Kamasa = quest item on kill.
- Reforging Bench = permanent system unlock.
- Campaign progression gate.
BEFORE THE FIGHT
Pre-Fight Preparation Checklist
| Done | Check | Why it matters | Quick fix |
|---|---|---|---|
| Sustained single-target DPS Verify you can out-pace the lava timer. | The fight is DPS-gated by the advancing lava; low DPS = pinned. | Single-target setup; temporary damage support swap. | |
| Fire Resistance Stack fire res. | Magma attacks deal fire; the lava itself is fire hazard. | Fire-crafted gear or Ruby Flask. | |
| Movement / reposition tool Have a way to reposition Mektul or yourself. | You must pull him out of the molten flow. | Movement skill or knockback. | |
| No pause reliance Plan consumables pre-fight. | The lava timer is not pauseable. | Pre-buff; don't rely on menu pause. |
PHASE BREAKDOWN
Combat Phases
Phase 1 · Timed Molten Fight
Trigger: Enter the Molten Vault arena.
Objectives- Kill Mektul before lava pins you.
- Pull him out if caught in flow.
- Burst during recovery windows.
No traditional phase split — the pressure is the advancing lava. Mektul occasionally gets caught in the molten flow; pull him out so the fight stays winnable.
Magma Arm attacks (uppercut, swing, smash, charged blast) are the main hit sources.

ARENA READING
Arena Reading
The Molten Vault is a rectangular arena with the molten flow advancing from one side. Keep the fight at the open edge; never let the lava get between you and your exit. When Mektul is caught in the flow, reposition so the fight stays at the safe edge.
The lava is fire hazard ground — standing in it is continuous damage on top of his attacks.
- Fight at the open edge, not the lava side.
- Pull Mektul out if he is in the flow.
- Lava = continuous fire damage.
BUILD-SPECIFIC STRATEGY
Build Considerations
This is a DPS check wrapped in a fire-hazard arena. Stack single-target damage and fire resistance. Ranged builds can kite him out of the lava more easily; melee must respect the Magma Arm timing and keep the fight at the edge. Minions help DPS but can body-block your dodges near the flow.
Because the timer is not pauseable, pre-buff and commit — no menu pacing.
- Melee: punish recovery; keep at the open edge.
- Ranged: kite him out of the lava.
- Minion: DPS help; watch body-block near flow.
- Fire res + single-target DPS; pre-buff, no pause.
