What Mastery gear is
Mastery equipment was added for characters who finished the 3rd class change and reached level 400. Its first grade is Bloodangel. In the story, the apostle-blacksmith James forged it with Lugard's power. Mastery armor comes in three kinds: normal, Excellent and set items. Later grades share the same idea across all classes; the fan wiki lists them as Darkangel, Holyangel, Awakening Soul, Blue Eye, Silver Heart, Manticore, Brilliant and Crimson Apocalypse, and the official guide's 10th grade is the Lightning gear.
Bloodangel (1st grade)
- Normal pieces drop in the Debenter and Uruk Mountain maps.
- Excellent pieces drop only in the Nars map. They roll 1-2 of six armor options: Max HP +300, Max MP +180, damage taken -195, reflect 5% damage, defense success rate +10%, or Zen from monsters +50%.
- Set pieces come through Ruud, the currency earned in event maps such as Blood Castle, Devil Square, Chaos Castle and Illusion Temple. Priest James sells a sealed set for your own class only; you unseal it at the Chaos Goblin with an Ancient Hero's Soul (100% chance).
- Bloodangel weapons are also sold by Lugard's Ruud shop in Elbeland; each has Excellent damage rate +10% plus 1-2 other Excellent options and maybe Luck.
| Class | Weapon | Damage | Strength / Agility |
|---|---|---|---|
| Blade Master | Bloodangel Sword | 299-310 | 886 / 287 |
| Grand Master | Bloodangel Staff | 110-116 / Wizardry 92% | 266 / 93 |
| High Elf | Bloodangel Bow | 248-258 | 182 / 1059 |
| Lord Emperor | Bloodangel Scepter | 224-236 / Wizardry 63% | 618 / 140 |
| Mirage Lancer | Bloodangel Lance | 161-172 | 387 / 282 |

Lightning gear (10th grade)
The 10th grade is not hunted but upgraded. An Apocalypse weapon at +11 or higher with 16 options (shields need 20 options), a Lightning Anvil, 30 Jewels of Bless, 30 Jewels of Soul, 1 Jewel of Chaos and 1 Jewel of Creation become a +0 Lightning weapon or shield at 100%, keeping Luck and the Excellent options. Armor works the same way: Crimson Apocalypse set armor at +11 with 16 options plus a Lightning Soul turns into Ancient Lightning set armor that keeps class, slot, Luck and all stat options. The upgrade materials are sold by Priest James for Ruud.
| Class | Weapon | Damage | Speed |
|---|---|---|---|
| Dark Knight | Lightning Sword | 880-895 | 40 |
| Dark Wizard | Lightning Staff | 305-314 / Wizardry 197% | 30 |
| Elf | Lightning Bow | 1366-1409 | 55 |
| Dark Lord | Lightning Scepter | 1001-1025 | 40 |
| Slayer | Lightning Short Sword | 847-938 | 45 |
| Illusion Knight | Lightning Blade | 880-912 | 45 |

Mastery earrings
Earrings are an accessory slot for all classes, with a left and a right earring. Wearing the left and right earring of the same grade activates a set option. They are enhanced up to +15 at the Chaos Goblin in Noria with Lapidary Stones and Zen; a failed attempt never destroys the earring, but after +7 it resets it to +0. Lapidary Stones are made at the Goblin from 10-jewel bundles such as Jewel of Life, Soul, Chaos, Creation or Harmony.
| Earring | Level (left / right) | How to get | Set option |
|---|---|---|---|
| Earring of Wrath (1st) | 300 / 700 | Mastery Accessory Box from Moss in Elbeland, opened with 1 Jewel of Bless | Ignore enemy DEF +1%, all stats +4 |
| Earring of Frost (8th) | 1,000 / 1,050 | Upgrade an Earring of Foliage +11 to +15 with a Casting Mold of Frost (60% at +11, 100% at +15) | Ignore enemy DEF 8%, all stats +11, Mastery damage +100 |
Each earring also rolls 1-3 random options. The Earring of Wrath draws from options such as Skill Attack +17, Excellent damage +35 or Max HP +200 (left) and attack speed +7 or Excellent rate +4% (right); the Earring of Frost has stronger ones such as Max HP +1000, Excellent damage rate +11% and Mastery Attack/Wizardry +145.

Changing options
The options of Mastery set armor and weapons can be rerolled with a Mysterious Stone; see Excellent Items for the possible results. For even higher gear, see Legendary Equipment.
