MU Online Artifacts – Types, Grades & Upgrades

Artifacts arrived in Season 18 as an entirely new equipment class. They sit in their own dedicated slot board — they don't compete with any gear you already wear — and they're shaped like puzzle pieces made of joined hexagons. Fill every slot and you get All Stats +100 for free.

What Artifacts Are

Property	Detail
Slot	A dedicated artifact board — open it from the Artifact button in your inventory
Shape	Joined hexagons — the number of hexagons is the type (1 hexagon = Type 1, up to Type 7)
Options	Each artifact rolls one random option from its type's pool
Enhancement	Up to +15 — and it is never destroyed on failure
Grade	A separate axis, 1–10, set by the option value rolled at creation
Requirement	Level 800 for the Spider Artifact line

The 7 Artifact Types

Type 1	Type 2	Type 3	Type 4	Type 5	Type 6	Type 7

Type	Option pool (one is rolled)	Value at +15

Type 2	Strength · Agility · Vitality · Energy · Command	+56 to the rolled stat
Type 3	Max HP · Max Mana · Max AG · Max SD	+158
Type 4	Excellent Damage · Critical Damage · Attack Speed · Skill Attack Power	+78 excellent or critical · +20 attack speed · +56 skill attack

Type 6	Min/Max Attack, Wizardry or Curse Power	+56
Type 7 (rare)	Max Attack · Wizardry · Curse Power	+62 — the strongest roll

How to Craft an Artifact

Artifacts are made from Artifact Pieces, and there is only one source: the Barca event map.

Step	What to do
1	Farm the Fortress of the Imperial Guard: Barca event map (level 1,000+, once per day) for Spider Artifact Pieces and Artifact Enhancement Stones
2	Take a piece to the Chaos Goblin in Noria
3	Add Jewel of Creation ×50 and 10,000,000 zen
4	Combine — 70% success (originally 80%, lowered in Season 19) for one random Type 1–7

You can bulk-combine up to 30 at a time. On failure all materials are consumed. The type and grade are random, so expect to make many before you get the ones you want.

Enhancing

Rule	Detail
Maximum	+15, at the Noria Chaos Goblin
Materials	Artifact Enhancement Stone + zen
On failure	The artifact is never destroyed — it simply drops one level
Disassembly	Any artifact breaks back down into 1 Artifact Enhancement Stone

Grades 1–10

The grade shows in brackets	Grade colours	The upgrade window

Season 19 added grades. The grade is the starting value of the artifact's option, shown in brackets beside it — a grade-8 artifact simply begins from a far higher number than a grade-1. Attack-speed options cap at grade 5.

Step	What to do
1	Get two artifacts with the same type, same option and same grade
2	Chaos Goblin → [Equipment Enhance/Craft] → Artifact Grade Upgrade
3	Right-click the main artifact — the sub artifact and stones auto-register
4	Confirm. The main artifact's grade rises by 1 and keeps its enhancement level

Grade	Enhancement Stones	Zen	Chance
1 → 2	20	10,000,000	90%
2 → 3	25	10,000,000	85%
3 → 4	30	10,000,000	80%
4 → 5	35	10,000,000	75%
5 → 6	40	10,000,000	70%
6 → 7	45	10,000,000	65%
7 → 8	50	10,000,000	60%
8 → 9	55	10,000,000	40%

Important limits
On failure only the sub artifact is destroyed — the main one survives with its enhancement intact
Grade 9 cannot be upgraded to grade 10
Grade upgrading only works during artifact combine events
Type-4 attack speed options cannot be grade-upgraded at all

Option Pools & Roll Rates by Artifact Type

From the server’s artifact files: which options each of the seven Spider Artifact types can roll and how likely each is, plus how often each type comes out of a fragment. The option’s grade (1–10) is rolled separately with the same curve for every option — see the table below the pools.

Artifact	Drop share	Possible options (chance)
Spider Artifact Type 1	27.1%	Increase Defense (30%) Increase Defense Success Rate (30%) Increase Base Armor (20%) Damage Reduction (20%)
Spider Artifact Type 2	26.0%	Increase Strength (20%) Increase Agility (20%) Increase Stamina (20%) Increase Energy (20%) Increase Command (20%)
Spider Artifact Type 3	21.0%	Increase Max Life (20%) Increase Max Mana (20%) Increase Max AG (30%) Increase Max SD (30%)
Spider Artifact Type 4	21.0%	Excellent Damage Increase (40%) Critical Damage Increase (40%) Increase Attack Speed (<0.1%) Increase Skill Attack Power (20%)
Spider Artifact Type 5	2.4%	Increase Elemental Defense (20%) Increase Elemental Attack Power (20%) Increase Elemental Defense Success Rate (30%) Increase Elemental Attack Success Rate (30%)
Spider Artifact Type 6	2.4%	Increase Max Attack Power/Wizardry (20%) Increase Min Attack Power/Wizardry (10%) Attack Power/Magic Increase (20%) Increase Maximum Curse Power (20%) Increase Minimum Curse Power (10%) Increase Curse Power (20%)
Spider Artifact Type 7	0.1%	Increase Max Attack Power/Wizardry (30%) Attack Power/Magic Increase (20%) Increase Maximum Curse Power (30%) Increase Curse Power (20%)

Option grade roll

Grade	1	2	3	4	5	6	7	8	9	10
Chance	1.8%	6%	10%	15%	17%	20%	15%	10%	5%	0.2%

Grade 6 is the most common roll and grade 10 appears once in 500 artifacts — which is why the grade upgrade mix exists.

FAQ

Are artifacts worth farming?
Yes — they occupy slots nothing else uses, enhancement can't destroy them, and a full board gives All Stats +100. The only real cost is Barca runs for pieces.

What's the difference between level and grade?
Level (+0 to +15) is how much you've enhanced it. Grade (1–10) is the starting value it rolled at creation. A high-grade, low-level artifact can beat a low-grade, high-level one.

Which type is best?
Type 7 is the rare tier with the highest values (+62 max attack, wizardry or curse). Beyond that it depends on your build — Type 4 for attack speed, Type 3 for survivability, Type 2 for raw stats.

Can I lose an artifact?
Only as the sub material in a failed grade upgrade. Enhancement failures never destroy artifacts.
