RaidHoursMIR4 Secret Peak Boss Guide: Spawn Times, Respawns & Local Time
Updated on 2026-07-06
The MIR4 Secret Peak boss rotation is one of the most reliable field farms in the game, and knowing exactly when each spawn lands is the difference between an easy kill and an empty map. Secret Peak (Cima Inexplorada) hosts two rotating field bosses — the Lower Red Boss and the Upper Red Boss — each up for roughly 15 minutes per spawn, four times a day on server time.
This guide lays out every respawn window in a clean table, explains where Secret Peak fits in your Darksteel farming loop, and shows you how to convert those server-time spawns into your own local clock so you never miss a boss again.
What is Secret Peak in MIR4?
Secret Peak is a high-level field zone where two named world bosses spawn on a fixed daily cadence. Unlike the sealed weekly world bosses (like Nerkan or Turkan, which appear sealed and invulnerable hours before they become attackable), the Secret Peak bosses are field bosses — they spawn attackable and stay up for about 15 minutes before despawning.
There are two targets to track:
- Lower Red Boss (Jefe Rojo de Abajo) — the lower-tier spawn, four windows per day.
- Upper Red Boss (Jefe Rojo de Arriba) — the higher spawn, offset from the Lower boss so the two never fully overlap.
Because they run on a short 15-minute window, punctuality matters. Arrive a few minutes early, tag the boss, and be ready — there is no long sealed phase to wait through like on the weekly world boss circuit.
Secret Peak boss spawn times (server time)
Below are the full daily respawn windows for both Secret Peak bosses. All times are server time and each boss stays up for roughly 15 minutes.
| Boss | Spawn 1 | Spawn 2 | Spawn 3 | Spawn 4 | Duration |
|---|---|---|---|---|---|
| Lower Red Boss (Abajo) | 01:00 | 07:00 | 13:00 | 19:00 | ~15 min |
| Upper Red Boss (Arriba) | 04:00 | 10:00 | 16:00 | 22:00 | ~15 min |
Notice the pattern: the two bosses are staggered three hours apart, so on a good day you can chain a Lower spawn and an Upper spawn into a single farming session. The daily server reset happens at 18:00, which sits neatly between the 13:00 and 19:00 Lower Red windows.
Important — verify in-game: these respawn times are community intel gathered by players and can vary from server to server. Always confirm the exact spawn on your own server, and re-check after the weekly maintenance, since patches occasionally shift field-boss timers.
Where Secret Peak fits in your Darksteel farming loop
Secret Peak isn't just about the boss kills — it's part of the broader daily grind for Darksteel and upgrade materials. The bosses drop farmable loot, and the zone slots in alongside your other daily material runs.
The natural companion to Secret Peak is Magic Square (Cuadrado Mágico), the dedicated daily farming content for Darksteel and materials. A typical efficient day chains these together — for example, hit a Chamber of Fury or Chamber of Frenzy run, then swing over for a Secret Peak spawn while your cooldowns reset. Every one of these events runs on server time, so building a single unified schedule pays off fast.
Rather than juggle a dozen server-time numbers in your head, you can see the entire daily and weekly rotation — Secret Peak, Magic Square, and the sealed world bosses — laid out and converted to your timezone on the RaidHours world events tracker.
How to see Secret Peak spawns in your local time
The single biggest mistake new players make is treating server time as their own local time. MIR4's schedule is published in server time, but your region runs on a different offset. RaidHours does the conversion for you automatically.
Supported regions and their offsets from UTC:
| Region | UTC offset |
|---|---|
| ASIA | UTC+8 |
| INDIA | UTC+6 |
| MENA | UTC+3 |
| EU | UTC+2 |
| SA | UTC-3 |
| NA | UTC-4 |
Pick your region on RaidHours and every Secret Peak spawn — plus the daily 18:00 reset — is shown in your local clock, with a live countdown to the next boss. You can also set alarms and export the schedule to your calendar as an ICS file, so the next Lower or Upper Red Boss window lands as a reminder on your phone. It's free and needs no registration.

What time does the Secret Peak boss spawn in MIR4?
The Lower Red Boss spawns at 01:00, 07:00, 13:00, and 19:00 server time, and the Upper Red Boss spawns at 04:00, 10:00, 16:00, and 22:00 server time. Each boss is up for about 15 minutes. These are community-sourced times and can vary by server, so verify in-game.
How long does a Secret Peak boss stay up?
Each Secret Peak field boss stays up for roughly 15 minutes per spawn. Unlike the sealed weekly world bosses, there is no long invulnerable phase — the boss appears attackable, so arrive a few minutes before the window to tag it in time.
Are the Secret Peak Lower and Upper bosses the same fight?
No. The Lower Red Boss (Jefe Rojo de Abajo) and Upper Red Boss (Jefe Rojo de Arriba) are two separate spawns on staggered timers, three hours apart. This lets you potentially catch both in a single farming session at Secret Peak.
What does the Secret Peak boss drop and why farm it?
Secret Peak is a field-farming zone tied into your daily Darksteel and material grind. It pairs naturally with Magic Square, the dedicated daily Darksteel farming content, so most players run both as part of one efficient daily loop.
Do Secret Peak boss times change after maintenance?
They can. Field-boss timers occasionally shift after the weekly maintenance patch, and spawns already vary between servers since the community intel isn't officially published. Always re-check the timers in-game after an update, or use a tracker that keeps its schedule current.
How do I convert Secret Peak server times to my local time?
Use the RaidHours tracker: select your region (ASIA UTC+8, INDIA UTC+6, MENA UTC+3, EU UTC+2, SA UTC-3, or NA UTC-4) and it converts every server-time spawn to your local clock, with a live countdown, alarms, and ICS calendar export. It's free with no registration.
