MIR4 5th Anniversary Roulette Event Guide

The MIR4 5th anniversary celebration packs in a lot—Spirit Summoner pre-registration, the Boosting World growth acceleration plan, an original theme song and music video, and a roulette event spanning five full weeks. Among these, the roulette is one of the higher-value giveaways. It costs no in-game resources, demands no intensive grinding, and only requires completing daily webpage missions to earn spins. That said, maximizing the rewards is not just about finishing the missions—it comes down to making the right character choice before you even start. The roulette event locks your character selection permanently, with no option to switch later.

Event Rules and How to Participate

The official name of the MIR4 5th Anniversary roulette event is "5th Anniversary, 5 Weeks of Gifts." It runs from August 4 at 09:00 (UTC+8) through September 8 at 08:59, covering a full five-week period. This is not an in-game event accessed through the game client. All participation takes place on the MIR4 5th Anniversary dedicated webpage. After logging into the event page, you select a character to bind—this character becomes the sole recipient of all roulette rewards for the entire event.

Event flow:

Character binding: Log into the 5th Anniversary event page and select the character that will participate in the roulette. Once confirmed, the binding is permanent.

Daily missions: Complete the four missions posted on the event page each day to earn one roulette spin.

Claiming rewards: Roulette rewards are sent directly to the bound character's in-game mailbox. Under normal conditions, they arrive within one to five minutes, though delays may occur during peak traffic.

Spin limit: A maximum of one roulette spin is available per day, totaling roughly 35 spins across the full five-week event window.

The specific daily mission objectives have not been announced in advance and will only become visible once the event page officially opens. Judging by the design of past MIR4 events, the tasks will likely center on routine gameplay—logging in, defeating designated monsters, completing specific dungeons, gathering resources, and similar activities. The overall difficulty should remain moderate.

One rule deserves separate emphasis: all four daily missions must be completed to earn a single roulette spin. Finishing three out of four yields nothing. If you find yourself short on time on a given day, it is more efficient to skip that day entirely and resume the next—partial completion offers zero return, so doing half the work is the same as doing none.

Character Binding—Choose Carefully

Character selection is the single most consequential decision in the entire roulette event. Per the official rules, once a character is bound, the choice is irreversible.

What this means in practice:

No reselection: After binding is confirmed, switching to a different character for the event is not supported.

Fixed reward delivery: All roulette rewards earned across the five weeks will be sent exclusively to the bound character's mailbox.

Alt-character risk: Binding the event to a seldom-used alt means that even if rare rewards are drawn, their value may go largely unrealized.

For these reasons, the bound character should be one you invest in long-term—a character with a solid gear foundation and high daily play frequency. The 5th anniversary also introduces the new Spirit Summoner class, Miho, launching on August 18. This timing creates a strategic tension: the roulette event begins on August 4, but Miho cannot be created until August 18, making it impossible to use Miho for the early phase of the roulette.

The most reliable approach under these conditions: bind your current main character to the roulette event, and register Miho separately through the pre-registration page. This ensures your main continues receiving roulette rewards throughout all five weeks while keeping Miho's development path unaffected. Although roulette rewards earned after Miho's launch could potentially aid her growth, the reward list has not yet been fully disclosed, so there is no way to confirm in advance whether it includes critical progression resources. Between waiting for unknown rewards and securing guaranteed benefits on an already-established main, the latter offers the clearer outcome.

Making the Most of Five Weeks of Spins

Across the five-week event window, players can earn up to roughly 35 roulette spins. Maintaining daily participation will produce the most complete reward accumulation, but the event's long duration makes missed days a real risk.

The periods most likely to disrupt mission consistency:

The new class launch window around August 18: Once the Spirit Summoner Miho becomes available, players may shift the bulk of their attention to leveling the new class, causing the webpage missions to slip.

The final stretch approaching early September: As the event nears its end, participation frequency can taper off due to event fatigue, leading to missed rewards in the closing days.

To stay on track, establish a fixed routine early. For example, open the event page before launching the game each day, complete the webpage missions first, then move on to in-game activities. Many of the webpage tasks are likely cumulative or login-based and do not require completing all game-related steps immediately—accepting the missions early and noting them down reduces the chance of forgetting later.

On the reward delivery side, a brief delay is normal. If rewards do not appear immediately after a spin, avoid repeating the action. The recommended steps:

Wait a few minutes, then refresh the in-game mailbox.

Check network stability and the event page status.

If a substantial delay occurs with no delivery, save a screenshot and contact official customer support.

Treating a delivery delay as a failed spin can lead to unnecessary duplicate actions—patience here avoids wasted effort.

Other 5th Anniversary Content

Beyond the roulette, the MIR4 5th anniversary celebration includes several parallel activities worth noting:

Spirit Summoner pre-registration (August 4–18): Select a character in advance to claim pre-registration rewards. As with the roulette, the character choice is permanent.

Boosting World growth acceleration: Provides development support for new characters, well-suited for players planning to try the new class or build a fresh account.

5th Anniversary theme song MV: The official track "Where the Mountain Peaks End" serves as a commemorative piece for the anniversary and has no direct impact on gameplay or reward acquisition.

One important distinction: the roulette event and the pre-registration event operate as two independent activities. Character bindings for one do not affect the other. You can, for example, register Miho through the pre-registration page while binding your current main character to the roulette—both sets of rewards will be delivered separately to their respective characters.

The MIR4 5th Anniversary roulette event spans a considerable period, and with the overlapping new class launch, the permanent character binding restriction, and the still-undisclosed reward list, advance planning makes a measurable difference. Binding the roulette to a long-established main character is the steadier choice for most players, while the new Spirit Summoner Miho can receive her own dedicated rewards through the pre-registration channel. Once the event page opens, players can fine-tune their plans based on the actual reward contents. Throughout the anniversary period, the most important thing is confirming the right character before clicking that bind button—because you only get one chance, and the character you choose should be the one you intend to play for the long term.
