MU Online Season 11 – Ferea, Darkangel & Bloodangel Weapons

Season 11 (2015–16) built the second floor of the mastery era: the Ferea kingdom opened as the endgame hunting ground, Darkangel became the first crafted mastery upgrade, the Ruud shop armed everyone with Bloodangel weapons, and the ancient Archangel weapons ascended to Blessed form. From the original patch notes with the original artwork.

Ferea – the Forgotten Kingdom

Ferea — south of Kanturu, on the Tarkan desert	An elemental region — all five elements roam it

A kingdom of art and architecture buried by Tarkan's great earthquake — its risen knight order still patrols the galleries. Entry at level 400+ via the move window or Tarkan safe zone (176,38); field gates: red (198,173) → (107,67), blue (201,155) → (199,137). Excellent Darkangel gear drops here.

Ferea Knight — sword & shield vanguard	Ferea Fighter — steel fists	Ferea Archer	Ferea Priest — the blue flame	Lord of Ferea — the boss

Monster line	HP	ATK	DEF	Elem ATK / DEF
Ferea Knight (5 elements)	105,000	1,400–1,450	1,225	950–1,050 / 1,500
Ferea Fighter / Archer / Priest	Same band, rising per type — the toughest field monsters of their day

Darkangel Mastery Armor

The first mastery upgrade tier, for master level 600+. The lore writes the recipe: the Lorencia knights infused their Bloodangel armor with Sealing Stone shards to fight Ferea's risen knights — and Secneum's dark power dyed it black.

Craft rule	Details
Base material	Unsealed Bloodangel set piece, +11 or higher with +16 options
Catalyst	Sealing Stone Fragments — sold by Priest James (Elbeland 32,239)
Result	Darkangel piece of the same class and slot (Bloodangel Knight Gloves → Darkangel Knight Gloves)
Alternative	Excellent Darkangel drops straight from Ferea monsters

This craft chain — upgrade your worn set, don't replace it — became the template for every mastery tier since. Full ladder: Ruud guide.

Bloodangel Weapons

Priest James' shop grew a weapons rack — one per class, every purchase rolling a guaranteed 10% excellent damage rate plus 1–2 random lines (speed +7, HP/8 on kill, mana/8 on kill, ATK per 20 levels +1.5, ATK +42), with random Luck. The 3-option version is fixed: exc 10% + speed +7 + ATK per 20 levels.

Bloodangel Sword (Blade Master)	Bloodangel Magic Sword (Duel Master)	Bloodangel Staff (Grand Master)	Bloodangel Bow (High Elf)
Bloodangel Stick (Dimension Master)	Bloodangel Book (off-hand)	Bloodangel Scepter (Lord Emperor)	Bloodangel Lance (Mirage Lancer)

The Blessed Archangel Upgrade

Step	Details
1. The weapon	Your Absolute Archangel weapon at +15 with +16 options
2. Heavenly Steel ×10	Drops from field bosses and boss battles — only for Absolute-weapon owners and their same-map party
3. Archangel's Hammer	Mix the 10 steel at the Noria Chaos Goblin
4. Upgrade	Weapon + Hammer → Blessed Divine Archangel weapon — higher attack, better options, and its own unique skill

Absolute Sword — BK/MG/DL · 265–275 ATK, spd 45	Absolute Staff — DW/MG · 153–165, 94% wizardry	Absolute Crossbow — Elf	Absolute Scepter — Dark Lord	Absolute Stick — Summoner

Each carries two skills — its weapon skill plus Archangel's Will, a party buff granting +200 PvP attack damage and +50 skill attack to everyone in range — and a fixed excellent suite: exc damage rate 10%, ATK/wizardry +2 per 20 levels, ATK/wizardry +57, speed +7, HP/8 and mana/8 on kill.

Twelve years after the Blood Castle quest first handed out Archangel weapons, they finally got a second act.

New Elemental Skills

Class	Skill	Element	Effect
Blade Master	Fire Blow	Fire	3–4 hit Blow with burn effect
Grand Master	Meteor Strike / Meteor Storm / Soul Seeker	Earth / Earth / Dark	Focused meteors, a screen-wide storm (8 targets), and a concentrated spirit nuke
High Elf	Focus Shot	Wind	Multi-shot concentrated into one target, 3–4 hits — the elf DPS skill of the modern era
Dimension Master	Fire Beast / Aqua Beast	Fire / Water	Elemental beasts maul the target 3–4 times

FAQ

Where can I play Season 11?
Browse the Season 11 private servers listed — all of this ships in later versions too.

Is Darkangel worth crafting or should I farm excellent drops in Ferea?
Both: craft the set pieces from your existing Bloodangel (+11/+16 is cheap by ML600), and hunt Ferea for the excellent versions on top.

Which new skill mattered most?
Focus Shot — it redefined elf DPS — with Meteor Storm as the farming favorite.

Do the RF/GL socket items match the older classes' gear?
Yes, same 380/400 structure, bonus options and set socket options — parity at last.
