Glossary

MU's chat looks like another language on day one. That's because it is: twenty years of the game produced an abbreviation for everything. Here's the translation.

Items

Word What it means
set the five-piece outfit: helm, armor, pants, gloves and boots
exc excellent — an item with an extra option, marked in blue on the sheet
anc ancient, an item from an old set, with the name in blue
+13 the item's level. It goes up to +15
option, additional the +4 / +8 / +12 next to the level, which comes from Jewel of Life
luck gives critical hits — and +20 chance in the Chaos Machine
full a complete set, usually all at the same level
socket an item with slots where you mount bonuses
wings the back item. The Dark Lord uses a cape instead. See wings
dura durability. At zero, the item stops giving its bonus

Jewels

Almost everyone calls them by the first name:

Abbreviation Jewel What it does
bless Jewel of Bless takes the item up to +6, always succeeds
soul Jewel of Soul takes it up to +9 — and here it never fails
chaos Jewel of Chaos the base of the Chaos Machine recipes
life Jewel of Life adds the additional option
creation, cre Jewel of Creation
guardian, gua Jewel of Guardian
harmony, harm Jewel of Harmony

Five of them drop while hunting: Chaos (from monster level 12 up), Bless and Soul (25), Life and Creation (46). Guardian and Harmony drop from no monster at all — they come from events, from recipes or from another player. See jewels.

From +10 up it's no longer a jewel: it's the Chaos Machine, and it can break the item.

Progression

Word What it means
reset going back to level 1 in exchange for points. See reset
GR grand reset — the reset of resets, ten at most
ML master level, the tree that opens at 400
rate the world's speed. Here it's x200
evolution, change becoming the second or third class
stat, point strength, agility, vitality, energy, command
build how you distribute your points

Places and hunting

Word What it means
spot a good place to hunt. "you're in my spot" = someone took the place
drop what falls from a monster
farm, farming hunting on repeat, after items or zen
kundun the big bosses — and the villain of MU's story
invasion special monsters that spawn at a set time
AFK away from keyboard
helper the client's automatic hunting. See the Helper

People

Word What it means
PK someone who killed another player and got marked
party, pt group. See party and guild
guild the guild
GM a member of the server staff
buff a temporary boost someone casts on you

Classes

Abbreviation Class
DW Dark Wizard, the mage
DK Dark Knight, the warrior
ELF, FE Fairy Elf, the archer
MG Magic Gladiator
DL Dark Lord
SUM, SU Summoner

And once someone has evolved — there are two evolutions, and the second is the top:

Class 1st evolution 2nd evolution
Dark Wizard Soul Master (SM) Grand Master (GM)
Dark Knight Blade Knight (BK) Blade Master (BM)
Fairy Elf Muse Elf (ME) High Elf (HE)
Magic Gladiator Duel Master (DM)
Dark Lord Lord Emperor (LE)
Summoner Bloody Summoner (BS) Dimension Master (DM)

Yes, DM is ambiguous: it works for the Magic Gladiator and for the Summoner. In practice you can tell from the model.

Money

Word What it means
zen the game's money, which drops from monsters
WCoin, WC the outside currency, earned in events and bought on the site
vault the account's warehouse, separate from the character's bag

Abbreviations you'll see that don't apply here

Old MU guides are full of event acronyms. These show up everywhere on the internet and have no use on this server:

Abbreviation What it is Why it doesn't apply
CC Chaos Castle never ran here
IT Illusion Temple never ran here
IG Imperial Guardian never ran here

What actually runs is in events.
