MU Online Season 21 Mastery Set RUUD Upgrade Guide

This guide explains, in simple English, how to upgrade your Mastery (RUUD) sets in MU Online Season 21 – starting from Bloodangel and going all the way up to the Ancient Lightning (Lightning) Set. You’ll learn where to use RUUD, which materials you need, and how the Chaos Machine combinations work for each step.

Short version: You buy sealed or upgrade materials with RUUD from Priest James, then use the Chaos Machine in Noria to evolve your set step by step: Bloodangel → Darkangel → Holyangel → Awakening Soul → Blue Eye → Silver Heart → Manticore → Brilliant → Apocalypse → Lightning.

What Are Mastery (RUUD) Sets?

Mastery sets are special armor sets made for Master Level (3rd class) characters. They’re bought and upgraded using RUUD, a special currency earned mainly from events and mini-games.

You can use RUUD at NPC Priest James in Elbeland (32, 239) or Event Square to buy sealed mastery sets, upgrade Souls/Anvils, weapons and other end‑game items.

Tier Mastery Set Name Common Short Name
1st Mastery Bloodangel Set BA
2nd Mastery Darkangel Set DA
3rd Mastery Holyangel Set HA
4th Mastery Awakening Soul Set Awakening / Soul
5th Mastery Blue Eye (Frost) Set Blue Eye
6th Mastery Silver Heart (Forefathers) Set Silver Heart
7th Mastery Manticore Set Manticore
8th Mastery Brilliant Set Brilliant
9th Mastery Apocalypse Set Apocalypse
10th Mastery Ancient Lightning / Lightning Spirit Set Lightning

Step 1 – Getting RUUD & Reaching Priest James

RUUD is a special currency that you use only in the Ruud Shop (Priest James). You mainly get it from:

  • Event maps: Chaos Castle, Blood Castle, Devil Square, Illusion Temple, Doppelganger, Maze of Dimensions, etc.
  • Special bosses and higher-end event rewards.
  • Some quests and server‑specific rewards (depends on your server).

Once you have Ruud, go to:

  • Elbeland – Priest James at (32, 239)
  • Sometimes also Event Square, depending on server settings
Tip: Ruud is character‑bound on many official‑like servers, so you cannot always trade it. But items bought with Ruud (Souls, Anvils, etc.) are often tradable – check your server rules.

Step 2 – Unsealing Your First Mastery Set (Bloodangel)

Your very first Mastery set is Bloodangel. You usually don’t craft it from scratch – you buy it as a sealed mastery set from Priest James, then unseal it.

2.1. Buy the Sealed Bloodangel Set

  • Talk to Priest James → open the RUUD Shop.
  • Buy the sealed Bloodangel set for your class (e.g. Bloodangel of Sealed Fury, Transcendence, etc.).

2.2. Create Ancient Hero’s Soul

To unseal the set, you need an item called Ancient Hero’s Soul. This is crafted in the Chaos Machine in Noria using ancient set items as materials. The combination has 100% success when done correctly on official‑style configs.

2.3. Unseal the Bloodangel Set

  • Open the Chaos Machine in Noria.
  • Choose Regular Combination.
  • Put in:
    • 1 × Sealed Bloodangel armor piece (e.g. Sealed Helm).
    • 1 × Ancient Hero’s Soul.
  • Combine → You get a usable Bloodangel piece at level +0 with ancient set options.
Important: After unsealing, your Bloodangel armor is treated as a normal Mastery set piece and can be upgraded further via RUUD to higher tiers.

Step 3 – General Rules for Mastery Set Upgrades

Every upgrade from one Mastery tier to the next follows the same basic rules:

  • Base item requirement:
    Your current Mastery piece (helm/armor/pants/gloves/boots) must usually be at least +11 with +16 additional defense (Jewel of Life option).
  • Combination material:
    Each tier needs a special Soul or Stone, purchased with RUUD from Priest James:
    • Sealed Stone Shard – Bloodangel → Darkangel
    • Holyangel Soul – Darkangel → Holyangel
    • Awakening Soul – Holyangel → Awakening
    • Frost/Blue Eye Soul – Awakening → Blue Eye
    • Silver Heart Soul – Blue Eye → Silver Heart
    • Manticore Soul – Silver Heart → Manticore
    • Brilliant Soul – Manticore → Brilliant
    • Soul of Apocalypse – Brilliant → Apocalypse
    • Lightning Soul – Apocalypse → Lightning
  • Jewels used (armor):
    • Bloodangel → Darkangel: 10 × Jewel of Bless, 10 × Jewel of Soul, 1 × Chaos, 1 × Creation
    • All other tiers: 30 × Jewel of Bless, 30 × Jewel of Soul, 1 × Chaos, 1 × Creation
  • Success chance:
    On Webzen-like settings, the combinations for Mastery upgrades are typically 100% success if you use the correct materials. Some private servers may lower the success rate, so always check the Chaos Machine preview on your server.
  • What is kept / reset:
    • Kept: Item type, class, Luck, Excellent options, Ancient set options.
    • Reset: Item level (back to +0) and Jewel of Life & Harmony options.
  • Upgrade per piece: Each armor part is upgraded separately, so a full 5‑part set needs 5 combinations per tier.
Rule of thumb: Don’t waste too many Jewels of Life / Harmony on a set if you plan to upgrade it soon – those options will be wiped when you evolve the armor.

Step 4 – Full Armor Upgrade Path (Bloodangel → Lightning)

Below is a simplified overview of how to upgrade your armor pieces through all Mastery tiers. All combinations are done in the Chaos Machine in Noria.

From Set To Set RUUD Combination Item Jewels Needed (per part) Typical Level Requirement*
Bloodangel +11 / +16 Darkangel Sealed Stone Shard 10 × Jewel of Bless
10 × Jewel of Soul
1 × Jewel of Chaos
1 × Jewel of Creation 		Character Lv 600+ (Master)
Darkangel +11 / +16 Holyangel Holyangel Soul 30 × Jewel of Bless
30 × Jewel of Soul
1 × Jewel of Chaos
1 × Jewel of Creation 		Character Lv ~800+
Holyangel +11 / +16 Awakening Soul Awakening Soul Same as above (30 Bless / 30 Soul + Chaos + Creation) Character Lv ~900+ (server‑dependent)
Awakening +11 / +16 Blue Eye (Frost) Frost / Blue Eye Soul 30 Bless / 30 Soul + Chaos + Creation Character Lv ~1000+ (often Master 600+)
Blue Eye +11 / +16 Silver Heart Silver Heart Soul 30 Bless / 30 Soul + Chaos + Creation Character Lv ~1100+ (Master 700+)
Silver Heart +11 / +16 Manticore Manticore Soul 30 Bless / 30 Soul + Chaos + Creation Character Lv ~1200+ (Master 800+)
Manticore +11 / +16 Brilliant Brilliant Soul 30 Bless / 30 Soul + Chaos + Creation Character Lv ~1300+ (Master 900+)
Brilliant +11 / +16 Apocalypse Soul of Apocalypse 30 Bless / 30 Soul + Chaos + Creation Character Lv 1400+ (9th Mastery)
Apocalypse +11 / +16 Ancient Lightning (Lightning) Lightning Soul 30 Bless / 30 Soul + Chaos + Creation Character Lv ~1500+ (10th Mastery, S19–S21)

*Exact level and Master Level requirements differ by class and server, but Apocalypse is generally around Lv 1400 and Lightning around Lv 1500 on Season 19–21 style configs.

Step 5 – Upgrading Mastery Weapons & Shields via RUUD

Weapons and shields use the same basic logic, but instead of Souls they use Anvils. The path is similar:

Bloodangel → Darkangel → Holyangel → Soul → Blue Eye → Silver Heart → Manticore → Brilliant → Apocalypse → Lightning

Example – Bloodangel Weapon → Darkangel Weapon

  • Base: Bloodangel Weapon with at least +11 / +16 additional damage.
  • RUUD item: Darkangel Anvil from Priest James.
  • Jewels: 30 × Bless, 30 × Soul, 1 × Chaos, 1 × Creation.
  • Result: Darkangel weapon +0 / 0 options; Luck + Excellent options stay.

Example – Apocalypse Weapon → Lightning Weapon (10th Mastery Weapon)

  • Base: Apocalypse weapon +11 or higher with +16 add damage.
  • RUUD item: Lightning Anvil from Priest James (officially ~100,000 Ruud per anvil).
  • Jewels: 30 × Bless, 30 × Soul, 1 × Chaos, 1 × Creation.
  • Result: Lightning weapon +0 / 0 options, with Luck & Excellent options preserved.
Note: Just like armor, weapon combinations reset level and Jewel of Life bonus, so re-upgrade your Lightning weapon with Jewels of Bless/Soul and add options after the conversion.

Season 21 and What Comes After Lightning

In Season 21, the Lightning set is still the top Mastery tier (10th Mastery Armor/Weapon). Many servers also introduce Legendary equipment (for example, Temple Guard and Imperial sets) which:

  • Upgrade from Lightning using Temple Guard Soul / Temple Guard Anvil and similar items.
  • Also use RUUD and the Chaos Machine but are usually categorized as Legendary, not Mastery sets.
  • Are meant for the very late game (high Master Level, tough maps like elite zones and Swamp of Destruction, etc.).

These Legendary upgrades are a separate system; if you’re just starting with mastery gear, focus on reaching Lightning first.

Tips, Tricks and Common Mistakes

  • 1. Prioritize weapons and main armor first
    Your weapon and chest armor give the biggest power spike. Upgrade these before you worry about boots or gloves.
  • 2. Don’t over‑invest before upgrading
    Since level and Jewel-of-Life options are reset on upgrade, don’t waste huge amounts of Bless/Soul/Life on a set you plan to evolve soon.
  • 3. Always check the Chaos Machine preview
    The combination UI shows the success rate and materials. If something looks off (lower success, missing item), double‑check your recipe.
  • 4. Farm events for Ruud “passively”
    Run BC, DS, CC, Maze of Dimensions and similar events daily with MU Helper on, so you always have a pool of Ruud ready for new Souls/Anvils.
  • 5. Upgrade one full set before jumping to the next
    A complete, well-built Apocalypse set is usually better than a random mix of Apocalypse + Lightning parts with weak options.
  • 6. Always match Souls/Anvils to the correct set
    Using the wrong Soul/Anvil wastes materials and can fail. Make sure the name matches your target tier (e.g. Soul of Apocalypse only for Brilliant → Apocalypse).

Conclusion

That’s it! Now you know exactly how to upgrade Mastery set items via RUUD in MU Online Season 21, all the way from Bloodangel to Lightning.

Take it step by step, keep an eye on your Ruud, and always double‑check your combination materials in the Chaos Machine. Do that, and your character will be rocking top‑tier Mastery gear in no time.
