KMS bossing reference · About these guides
How far should you develop a weekly boss mule? A higher converted-stat score does not automatically produce proportionally more mesos. The meaningful gains often arrive when you unlock another clear or can reduce the party size for an existing one. That is a better starting point for deciding where to stop.
For the Korean boss lineup discussed in the source, one checkpoint worth examining is roughly 55,000–60,000 converted stats. The source groups the First Adversary, the Radiant Omen encounter, and Extreme Lotus around that progression range. The first two are descriptive English labels for the Korean encounters in this article, not verified GMS boss names or availability claims.
Around 80,000 is another checkpoint in the source, but reaching it can require substantially more equipment and progression resources.
This article follows Hamgun's Korean boss-progression video and its example scores and damage ratios. Converted stats are a third-party metric, not an official minimum. Class, level, Sacred Power, HEXA upgrades, experience, and party composition can change whether a clear is possible.
The source also predates final September 2026 crystal-rule changes. Treat it as a framework for deciding whether another upgrade changes your boss routine, rather than a current weekly-income table. None of these checkpoints establishes a GMS requirement or payout.
The Korean source's progression checkpoints
| Converted-stat range | Example boss goals | Progression focus |
|---|---|---|
| Around 35,000 | Normal Seren; Easy Kalos | A growth-event character's entry into Grandis bosses |
| Around 40,000 | Hard Seren; Easy Kaling | Compare solo plans with duo efficiency |
| Around 45,000 | Easy Bellona; Easy Kaling | Consider a Bellona party and Kaling solo consistency |
| Low-to-mid 50,000s | Normal Kalos | Improve account bonuses, HEXA, and mechanics |
| Around 55,000–60,000 | Normal First Adversary; Normal Radiant Omen; Extreme Lotus (KMS context) | A possible stopping point for a meso-focused alt |
| 60,000–70,000 | Existing higher bosses; Extreme Black Mage | Reassess the value of more investment |
| Low-to-mid 70,000s | Extreme Lotus and Normal Radiant Omen solo | Expand toward Kaling, Bellona, and Limbo |
| Around 80,000 | Hard First Adversary; Extreme Seren | Smaller parties and higher bosses |
| 80,000–90,000 | Existing higher bosses; Normal Bellona | An upgrade range with potentially fewer immediate changes |
| Low 90,000s and above | Hard Limbo and other higher bosses | Smaller parties and more solo options |
| Around 100,000 | Long-term Destiny weapon progression | Developing a major character rather than only weekly income |
These scores are neither boss-entry requirements nor official minimum-clear thresholds.
The same score can produce very different damage across classes, HEXA levels, and matchups. Use your own combat performance and practice records alongside any calculator result.
Three ways to judge a boss mule upgrade
Can you clear with fewer people?
A smaller party can be one of the biggest changes in a weekly routine.
Moving from three players to two, or from a duo to solo, can change each player's share of the rewards.
Crystal income and random-drop distribution are separate. Agree how valuable drops such as Pitched Boss accessories and Eternal equipment boxes are divided.
Before buying more gear, check whether better mechanics at your current setup could already support the smaller party.
Can the same party run several bosses?
With several bossing alts, recruiting and coordinating can become more inconvenient than the fights themselves.
That makes overlapping boss rosters useful: the same people can cover several fights together.
For example, running the Korean Radiant Omen encounter and Extreme Lotus back-to-back with similar members can reduce weekly recruitment work.
Efficiency includes mesos and the time needed to maintain the character's routine. Count both when comparing an upgrade.
Can you clear reliably with less damage headroom?
The video's discussion of lowering a ratio means clearing with less excess damage, not deliberately weakening the character.
Better mechanics can let you complete a fight with less headroom than before.
A narrow first clear and a dependable weekly clear are different achievements.
If repeated retries or very long fights are common, a theoretically lucrative boss list can still be an inefficient weekly routine.
Around 35,000: Normal Seren and Easy Kalos
The video's first checkpoint is roughly 35,000 converted stats.
Its main targets are:
- Normal Chosen Seren
- Easy Kalos the Guardian
The video gives example calculator ratios of approximately 150% for Easy Kalos and 200% for Normal Seren. These are that source's performance estimates, not in-game damage modifiers or guaranteed clears.
Building such a character from scratch solely with mesos can be a costly way to add a boss mule.
A character already developed with Hyper Burning or Korean Challenger support is a more natural candidate for this initial Grandis-boss goal.
Around 40,000: compare Hard Seren and Easy Kaling options
The next example goals are:
- Hard Chosen Seren
- Easy Kaling
You do not have to insist on solo clears immediately.
Compare investing for Easy Kaling solo with running Hard Seren and Easy Kaling as a duo.
For a boss mule, a reliable roster at a manageable cost can matter more than reaching the single highest boss.
Around 45,000: Easy Bellona, level, and Sacred Power
The Korean source introduces Easy Bellona around this checkpoint. This refers to the KMS encounter, not an announcement of a GMS release.
The video's examples include:
- Easy Bellona duo
- More consistent Easy Kaling solo
- Considering a Bellona party around level 280 and 380 Sacred Power
- Working toward level 285 and roughly 450 Sacred Power over time
Those are example progression goals, not official minimum-clear requirements.
The Korean boss guide lists Bellona's entry level as 280 or higher. The Korean Radiant Omen encounter is also listed at level 280, while Limbo requires level 285. Check the current entry rules for the content available on your server.
A higher calculator score cannot replace a missing level or Sacred Power requirement.
Low 50,000s: do not overextend solely for Normal Kalos
Normal Kalos becomes a central target in the source's low-to-mid 50,000 range.
Equipment replacements can become much more expensive here, reducing the immediate gain per meso spent.
If the upgrade adds no clear and does not reduce party size, the weekly return may barely change despite a higher score.
Develop these alongside equipment:
- HEXA skills
- Sacred Symbols
- Legion Champion
- Boss mechanics
- Reliable Easy Bellona clears in the Korean context
If you use temporary Challenger gear, check whether the same roster remains possible after it expires.
Calculating income from today's score alone can hide the later replacement cost.
Why 55,000–60,000 is a possible stopping point
One range the video emphasizes is roughly 55,000–60,000 converted stats. Its value comes from the available routine, not the number itself.
The Korean boss examples are:
- Normal First Adversary
- Normal Radiant Omen
- Extreme Lotus
The important part is not reaching exactly 55,000.
It is whether similarly developed party members can run several higher bosses together.
If a party formed for the First Adversary can also cover Extreme Lotus and Radiant Omen, the recurring schedule becomes easier to maintain.
The video gives example calculator ratios of about 120–130% for this discussion.
They assume substantial experience. Matching the score alone does not make the routine dependable.
Later, the video describes the same broad checkpoint as around 60,000. Read the range as an example, not a precise stopping rule.
Find the point where your character repeatedly clears the intended roster instead of stopping at an exact score.
60,000–70,000: recalculate the next upgrade's value
A higher score may have little immediate effect if it neither adds a boss nor reduces party size.
That is why the video describes this range as a potential plateau.
Revisit the character's purpose:
is it mainly a weekly meso alt, or an alt you want to develop into higher-end content? The right spending decision can differ substantially.
The source also mentions an Extreme Black Mage party as another target.
Black Mage is a monthly boss, so keep that reward schedule separate from the usual weekly-crystal calculation.
70,000–80,000: expanding solo options
From the low-to-mid 70,000s in the source, converting party fights into solo clears becomes more prominent.
Example goals include:
- Extreme Lotus solo
- Normal Radiant Omen solo
- Attempts at Normal Kaling solo
- Normal Bellona duo
- Joining a Normal Limbo party
The video also discusses covering Chaos Kalos and Normal Bellona with the same party.
At these higher checkpoints, ask how many bosses the same party can run consecutively, rather than focusing only on adding one encounter.
Around 80,000: another decision point
The source considers targets such as:
- Hard First Adversary
- Extreme Chosen Seren
- Reducing the party size for Normal Limbo
Turning a three-person fight into a duo can change the weekly reward share.
But each further step can require substantially more mesos.
That does not make raising every alt to 80,000 an efficient choice.
Compare the actual remaining equipment cost with the recurring improvement it would produce.
80,000–90,000: more stats may change less
The video identifies another range where substantial investment may not immediately change much.
Normal Bellona solo can be a meaningful goal, but not every boss will support a smaller party at the same time.
Choose a specific result for the investment instead of simply adding 10,000 to a calculator score.
For example:
- Turn one named boss into a solo clear
- Change an existing trio into a duo
- Enter a new higher-end encounter
- Prepare for Destiny weapon progression
The intended result should be clear before the spending begins.
Above 90,000: Hard Limbo and higher-end rosters
The source's low-90,000 range starts emphasizing Hard Limbo and other demanding bosses.
For earlier fights, progression may expand solo clears or reduce party size.
Class differences can become particularly significant even at the same converted score.
Use your own damage and practice runs instead of assigning the same party size to every character at a given number.
Around 100,000: long-term character development
At this stage, the plan resembles developing another main more than adding a simple weekly boss mule.
The video names Destiny weapon growth as a longer-term target.
The Korean system follows Genesis weapon progression. The official Korean description changes the weapon to level-250 equipment at its first growth stage while inheriting existing Potential, bonus stats, and Soul. This identifies the KMS system and does not establish its GMS release status.
Related Korean updates use the label Destiny First Transcendence Mission for that progression content; the English phrase here describes the Korean entry.
Weekly meso income alone becomes an incomplete measure of the investment.
Also consider whether you enjoy higher bosses and developing the character itself.
September 2026 crystal changes: what needs rechecking?
Crystal-rule changes are central when updating this source's income assumptions.
The September 10 Korean Test World notice proposed removing the 12 weekly-crystal sales per character limit. It also changed some boss-crystal prices.
The proposal included adjustments affecting:
- Extreme Lotus
- Normal Kaling
- Normal Radiant Omen
- Normal Bellona
- Normal Limbo
- Chaos Kalos
- Hard First Adversary
- Extreme Seren
- Extreme Black Mage
As a result, older calculations that remove lower bosses solely to fit a 12-crystal character cap need rechecking. A change to one limit does not establish every current account or world rule.
The source described the September 10 test proposal ahead of the September 17 live update. That date has now passed. Use the final KMS live notes and current sale values for a Korean calculation, or GMS's own rules for GMS; do not treat the old preview as today's earnings table.
What to record for a boss mule comparison
Adding up nominal crystal prices is not enough to measure real efficiency.
Record these too:
- Crystal proceeds you actually received
- Party size for each boss
- Total weekly fighting time
- Recruitment and travel time
- Failed attempts and retries
- Buff and consumable costs
- Equipment costs to reach the next checkpoint
- New bosses the upgrade would add
- Bosses where it would reduce party size
Keep chance-based Pitched accessories and Eternal boxes separate from reliable income.
One valuable drop does not turn into a weekly guarantee.
Boss mule FAQ
Must I stop at 55,000?
No.
The 55,000–60,000 range is the video's example of a potentially efficient Korean boss combination.
Class, level, Sacred Power, HEXA, experience, and a regular party can justify a different stopping point.
Why can I not clear a recommended boss at the same score?
The score does not capture every factor in practical bossing.
Important factors include:
- Character level
- Sacred Power
- HEXA upgrades
- Class burst structure
- Survival tools and execution
- The matchup
- Party synergy
- Mechanic knowledge
Compare your own combat performance and practice records with the example instead of using someone else's number alone.
Is solo always most efficient?
Not necessarily.
Solo can increase your share, but long or unreliable fights can make it a poor recurring routine.
For several weekly alts, quick and consistent duo or trio runs may be more manageable.
How many mesos will a boss mule earn each week?
There is no single amount across changing boss rosters, party sizes, and crystal values.
The source's September 2026 Korean rule changes also make old tables unsuitable without an update. GMS needs its own regional calculation.
Record your actual sale proceeds, then compare them with what the next progression step changes.
Where should you stop upgrading?
Look beyond the score and ask what the next upgrade changes. Start with the outcome you can identify.
For your current character, check:
- Does it add a clear?
- Can an existing fight use fewer party members?
- Can the same party cover several bosses?
Those three questions give the upgrade a purpose.
For a meso-focused Korean alt, the source's 55,000–60,000 roster is one candidate to examine.
For an alt you want to develop further, the higher ranges suggest staged solo and smaller-party goals.
The best stopping point is not simply the highest score.
It is the point where your character can repeat a useful boss roster reliably within the time and resource budget you want to spend.
