MU Online Season 7 (eX701) – Monster Wings, Socket Weapons & Arka War

Season 7 shipped as the eX701 update and gave the mid-game two of its most loved chases: the monster wings — boss-trophy wings between 2nd and 3rd tier — and ten craft-only 400-level socket weapons, each with its own lore. It also rebuilt Arka War registration and modernized the interface. Rebuilt here from the original patch notes with the original artwork.

The Monster Wings (2.5 Level)

Wings crafted from materials of specific bosses, carrying "one of the powerful options of 2nd and 3rd level wings". All equip at level 290 + 4×wing level:

	Wing	Classes	DEF	DMG+	Absorb	Material & hunting ground
	Cloak of Death	Dark Lord, Rage Fighter	27 (+3/lvl)	21% (+1/lvl)	13% (+2/lvl)	Death King's Bone Lost Tower 7 — Death King, Death Gorgon, Death Knight
	Wings of Chaos	Blade Knight, MG	46 (+3/lvl)	33% (+1/lvl)	30% (+2/lvl)	Hell Maine's Leather Aida — Hell Maine, Witch Queen, Blue Golem
	Wings of Magic	Soul Master, MG, Bloody Summoner	37 (+3/lvl)	35% (+1/lvl)	29% (+2/lvl)	Dark Phoenix's Flame Icarus — Dark Phoenix, Giant Drakan, Phantom Knight
	Wings of Life	Muse Elf	37 (+3/lvl)	35% (+1/lvl)	29% (+2/lvl)	Death Beam Knight's Soul Tarkan — Death Beam Knight, Beam Knight, Tantalos

Each wing rolls up to three option layers: (A) one of two wing-specific options — additional ATK or HP auto-recovery on Death/Chaos/Life, additional wizardry or curse on Magic — addable later with a Jewel of Life if missing; (B) random Luck; (C) by chance, 3% ignore defense or 5% full HP restore when hit — or nothing. The lore has a wink too: every description warns the magic "mutates during Bless/Soul upgrading, flipping the element info".

The 400-Level Socket Weapons

Wearable after the 3rd class change, impossible to loot — crafting only. Each carries original lore (the wind demon king's arsenal, Kanturu's lost technology, the fallen archangel unit):

	Weapon	Class	Stats	Recipe (scroll + materials)
	Sonic Blade	Blade Master	109–116, spd 35	Sonic Scroll + Ice Walker's Mane ×2 + Dark Iron Knight's Sword
	Cyclone Sword	Blade Master	129–144, spd 40	Cyclone Scroll + Mammoth's Fur ×2 + Dark Mammoth's Horn
	Blast Break	Blade Master, Duel Master	163–216, spd 30	Blast Scroll + Giant's Ice Shard ×2 + Dark Iron Knight's Sword
	Magma Spear	Blade Master	135–236, spd 35	Magma Scroll + Coolutin's Poison ×2 + Dark Mammoth's Horn
	Horn of Steel	Blade Master	177–206, spd 25	Horn Scroll + Giant's Ice Shard ×2 + Dark Giant's Axe
	Angelic Bow	High Elf	179–202, spd 45	Angelic Scroll + Ice Walker's Mane ×2 + Dark Mammoth's Horn
	Devil Crossbow	High Elf	167–218, spd 40	Devil Cross Scroll + Iron Knight's Heart ×2 + Dark Coolutin's Blood
	Spite Staff	Soul Master, Duel Master	wizardry 68%, spd 25	Spite Scroll + Iron Knight's Heart ×2 + Dark Giant's Axe
	Asura	Duel Master	115–140, wiz 56%, spd 45	Asura Scroll + Iron Knight's Heart ×2 + Dark Iron Knight's Sword
	Thunderbolt	Lord Emperor	127–154, wiz 38%, spd 40	Thunder Scroll + Mammoth's Fur ×2 + Dark Coolutin's Blood

How the Weapon Craft Works

	Material	Drops from	Used in
	Ice Walker's Mane	Ice Walker	Sonic Blade, Angelic Bow
	Mammoth's Fur	Giant Mammoth	Cyclone Sword, Thunderbolt
	Giant's Ice Shard	Ice Giant	Blast Break, Horn of Steel
	Coolutin's Poison	Coolutin	Magma Spear
	Iron Knight's Heart	Iron Knight	Devil Crossbow, Spite Staff, Asura
	Dark Mammoth's Horn	Dark Mammoth	Cyclone Sword, Magma Spear, Angelic Bow
	Dark Giant's Axe	Dark Giant	Horn of Steel, Spite Staff
	Dark Coolutin's Blood	Dark Coolutin	Devil Crossbow, Thunderbolt
	Dark Iron Knight's Sword	Dark Iron Knight	Sonic Blade, Blast Break, Asura

Craft (Noria Chaos Goblin)	Value
Ingredients	Combination Scroll + 2 lower materials + 1 dark material + three socket items at +7 with +4 options (empty sockets allowed)
Max cost / max rate	1,000,000 zen / 40% (Jewel of Luck allowed)
On failure	Everything is destroyed
Sources	Scrolls and all materials drop only in Raklion

This craft made Raklion farming and socket fodder the mid-game economy of the S7–S9 era — three +7 socket items per attempt at 40% is a brutal sink.

FAQ

Where can I play Season 7?
Browse the Season 7 private servers listed — and every later version keeps all of this content.

Which monster wing is best?
Wings of Chaos for melee (46 DEF, 30% absorb), Magic for casters, Life for elves — the Cloak of Death trades stats for the fastest craft path since Death King is the easiest boss of the four.

Are the 400 socket weapons better than Season 4 socket weapons?
Yes — higher base stats and post-400 equip requirements make them the socket endgame until Season 9-era gear.

Why does my server call Horn of Steel "Horn of Steal"?
A typo that shipped in the official English files and never died. Same mace.
