MU Online Evomon Event – Evolution Chain, Spawns & Reward Boxes

Evomon is MU Online’s evolution event monster: a creature that spawns on ordinary hunting maps, and every time it dies it has a chance to respawn one level stronger. The chain can climb over a hundred levels, the monster hardens with each step, and the reward box at the end scales with how far the chain got. Every number on this page comes from the server’s own EvolutionMonsterEvent.xml.

What Is the Evomon Event?

The event runs on a simple loop:

StepWhat happens
1. SpawnAn Evomon egg appears at a random spot on one of five field maps, at level 1.
2. KillAnyone can kill it. The killer gets the reward roll.
3. RewardOn this configuration the killer picks a card from the reward UI — you have 10 seconds to choose.
4. Evolution rollThe server rolls whether the chain continues. On success the next Evomon spawns one level higher about 15 seconds later, announced to the map.
5. Repeat or endThe chain climbs until an evolution roll fails, nobody kills it in time, or it despawns.
The timer is the real enemy. An Evomon despawns after 300 seconds plus 10 more per level — a level 1 lives five minutes, a level 60 lives fifteen. High-level chains die to the clock more often than to failed rolls.

Where It Spawns

Five maps host the event, every chain starting at level 1:

MapStart levelMap guide
Dungeon1Dungeon monsters & spawn map
Devias1Devias monsters & spawn map
Tarkan1Tarkan monsters & spawn map
Karutan 11Karutan 1 monsters & spawn map
Debenter1Debenter monsters & spawn map

The configured activity window on this server runs through most of the day (hours 1–22 in the event settings), so outside the small nightly gap there is almost always a chain running somewhere.

The Evolution Chain

Whether the chain continues is a probability roll. On this configuration (ChangePro 48, ProV 0.7) the chance is high at low levels and falls as the chain climbs — the server floors it so a chain always has some chance to continue. Three thresholds also change the monster itself:

Evomon levelBehaviour
1 – 20Uses one skill. Easy solo kills.
21 – 67Uses two skills.
68 – 124Uses three skills — treat it as a boss.
The level is remembered. This server runs memorize mode 1: the highest level a chain reaches is stored, and future chains build on that progress instead of always starting from scratch. Long-term, a map’s Evomon keeps getting further.

Stats by Level – the Actual Formulas

The base monster is modest — level 1, 1,000 HP, 35–60 damage, 21 defense. The scaling is what matters, and the config states it exactly:

StatFormula on this configurationMeaning
Damagebase + 10 × (level − 1)Linear: +10 damage per level.
Healthcompounds at ×1.05 per levelExponential: doubles roughly every 14 levels.
Defensecompounds at ×1.01 per levelSlow exponential growth.
Attack ratinglevel² / 8Grows with the square of the level — high chains hit low-defense characters reliably.
Blockinglevel × 3.4High chains start blocking hits.

Worked examples from those formulas:

Level~HPDamageSkillsDespawn timer
11,00035–6015:00
101,551125–15016:30
253,225275–30029:00
5010,921525–550213:10
7536,983775–800317:20
100125,2391025–1050321:30
These are the unmodified config values. The shape of the scaling — linear damage, exponential health — holds everywhere, but private servers tune the multipliers.

Golden (Special) Evomon

MU Online Golden Evomon

Each successful evolution also rolls a 2% chance (ChangeSpecPro 200/10000) that the next spawn is the Special Evomon instead — a golden variant that is an entirely different animal:

Regular Evomon (base)Special Evomon
Health1,00024,000,000
Damage35–602,200–5,500
Defense211,553
Call your guild. Twenty-four million health is a raid, not a solo kill — and the despawn clock still runs.

Reward Boxes – the Tier Ladder

The reward tier is driven by the Evomon’s level when it dies (one tier per ten levels). Each tier rolls a box, and the odds shift upward as the chain climbs:

Chain level at killBox you get
up to ~10Minor Evomon Box
~11 – 2050% Minor / 50% Standard
~21 – 30Standard
~31 – 4050% Standard / 50% Greater
~41 – 50Greater
~51 – 6050% Greater / 50% Luxurious
~61 – 70Luxurious
~71 – 8050% Luxurious / 50% Magnificent
~81 – 90Magnificent
~91 – 10050% Magnificent / 50% Legendary
~101+Legendary Evomon Box
On this configuration all six boxes currently share the same reward pool — Jewel of Soul, Scroll of Inferno or Scroll of Decay. The tier ladder exists in the config and many servers fill the higher boxes with much richer loot, so check what your server put inside before grinding a chain to 100.

Tips

TipWhy
Camp the announcementSuccessful evolutions are announced with a ~13 second notice before the next spawn. That is your window to reposition.
Pick your card fastThe reward UI gives you 10 seconds. Hesitate and the roll is wasted.
Bring burst at high levelsHealth grows exponentially but the despawn timer grows linearly — past ~level 70 the clock becomes the boss.
Low chains are free lootLevels 1–20 use one skill and die instantly. New players can farm them safely on Devias and Dungeon.
Watch for the gold flashThe 2% Special Evomon is worth interrupting anything for — on most servers its reward table is the best in the event.

FAQ

What is Evomon in MU Online?

An evolution event monster that spawns on regular field maps at level 1. Every kill triggers a roll for it to respawn one level stronger, forming a chain that can pass level 100. Rewards scale with the chain level at the moment of the kill.

Where does Evomon spawn?

On this configuration: Dungeon, Devias, Tarkan, Karutan 1 and Debenter, always starting at level 1. It appears at a random location on the map.

How strong does Evomon get?

Damage grows by 10 per level, health compounds at about 5% per level and roughly doubles every 14 levels, and past level 67 it uses three skills. A level 100 chain has around 125,000 HP and hits for over 1,000.

What is the Golden or Special Evomon?

A 2% roll on every successful evolution replaces the next spawn with the Special Evomon: 24 million HP, 2,200-5,500 damage and 1,553 defense. It is a raid boss and needs a group.

How long before Evomon disappears?

300 seconds plus 10 per level. A level 1 lasts five minutes; a level 60 lasts fifteen. If the timer runs out the chain ends.

What are the Evomon boxes?

Six tiers - Minor, Standard, Greater, Luxurious, Magnificent and Legendary - awarded by the chain level at the kill, one tier band per ten levels, with a 50/50 overlap between neighbouring tiers. Box contents are server-configured.

Does the Evomon chain reset?

On this configuration the highest achieved level is remembered (memorize mode 1), so chains build on past progress rather than always restarting from level 1.
