MIR4 Magic Square Boss Guide: Every Chamber Time, Explained

What the Magic Square is in MIR4

The Magic Square is a daily instanced farming zone in MIR4, separate from the weekly world boss rotation and from the field bosses at Secret Peak. Instead of a single once-a-day spawn, it opens in three distinct chambers at fixed server-time slots throughout the day, and each chamber stays open for one hour.

Because the Magic Square runs on repeating windows rather than a one-shot spawn, it's some of the most flexible content in the game: with several openings spread across the day, almost every player can find at least one chamber that fits their play session. The only requirement is knowing the server-time grid and converting it to your local clock — miss the hour and the chamber is sealed until its next slot.

All Magic Square chambers reset alongside the rest of MIR4's daily content at the 18:00 server-time daily reset, so a fresh farming day always begins from that anchor point.

Magic Square boss schedule (server time)

Here are all three chambers with their real opening times. Every value below is in server time — apply your server region's UTC offset to convert to your local clock, or let RaidHours do it for you.

A few things worth noting from the grid. The Chamber of Fury has the most openings — five per day — so it's the easiest chamber to slot into almost any schedule. The Chamber of Frenzy gives you four evenly spaced windows across the day. Chamber of Leader III is the scarcest: it opens only once, at 00:00 server time, so it's the one most players miss simply because they never converted midnight-server to their own clock.

What the Magic Square is for: Darksteel and materials

The Magic Square is pure farming content. Clearing its chambers is a core way to stockpile Darksteel and other crafting and upgrade materials that feed your gear progression. Unlike the competitive world boss windows, where clans fight over shared kills, the Magic Square is about consistent, repeatable resource income.

That's exactly why the schedule matters so much here. A single missed chamber isn't a disaster, but Darksteel and material farming is a numbers game — the players who pull ahead are the ones who reliably hit multiple chambers every day rather than catching one at random. Turning the server-time grid above into your local time, and setting an alarm for each slot you can realistically make, is the difference between casual and consistent farming.

• Chamber of Fury — five daily windows; best for stacking runs across a play session.
• Chamber of Frenzy — four spaced windows; good coverage from morning to night on server time.
• Chamber of Leader III — one nightly window at 00:00 server; easy to forget without an alarm.

How to see Magic Square times in your local timezone

RaidHours (raidhours.com) takes every server-time chamber above and rebuilds the Magic Square schedule in your local time — no mental math, no spreadsheets. It's free, needs no registration, and covers all six server regions with their real offsets: ASIA (UTC+8), INDIA (UTC+6), MENA (UTC+3), EU (UTC+2), SA (UTC−3), and NA (UTC−4).

• Live countdown to the next chamber opening so you always know how long until the Magic Square, a world boss, or the daily reset.
• Alarms you can set per chamber to get pinged before a window opens.
• Calendar export (ICS) so your Magic Square slots drop straight into Google Calendar, Apple Calendar, or Outlook.
• Region-aware conversion — pick your server and every listed time reflects the correct UTC offset.

You can line the Magic Square up next to the rest of your day — the weekly world bosses, the daily 18:00 reset, and Secret Peak field bosses — on the World Events tracker, all converted to the same local clock.

One caveat that applies to the whole schedule: times can change after the weekly maintenance. When a patch lands, re-check the tracker instead of trusting an old screenshot — RaidHours reflects the current windows so you're always aligned with the live game.
