MU Online Season 21 – Crusader, Imperial Gear & Aquilas Temple

Season 21 (2025–26) is the latest season. It added the Crusader — a holy knight of Lugard wielding a hammer and shield — and the 2nd Legendary Imperial equipment tier above Temple Guard gear. Around them came the Aquilas Temple hunting ground, the Forgotten Raklion elite zone, the 8th Guardian Rhino, a Deep Dungeon renewal, Crywolf improvements and max level 1,750. Rebuilt page-by-page from the original patch notes.

The Crusader

The Crusader — Allen

Story: in Elbeland served an order of holy knights devoted to Lugard, God of Light. Allen had just become their knight-commander when Kundun's war swept the continent and his order was sent to the fiercest battlefield. Their light techniques cut through Kundun's monsters, but endless waves pushed them back until they stood with their heels at a cliff edge. Allen dropped his weapon, watched his knights fall, and prayed to Lugard in desperation. Lugard's emblem rose into the air and brilliant light enveloped them all — their hearts burned again, Allen raised his weapon, and the losing battle turned into victory. Believing Lugard's light to be his mission, he trains on as a guardian, waiting for the next battle.

Basic info	Value
Creation	Freely creatable
Start town	Elbeland — low-level armor from NPC Lea (29, 236), weapons and skill orbs from NPC Marce (36, 219)
Base stats	HP 150 / MP 40 · STR 26, AGI 18, VIT 19, ENE 20
Class line	Crusader → Impact Crusader → Master Paladin → Sacred Paladin → Templar Commander
Weapons	Hammer (main hand) + Shield (off hand)
Style	High HP melee holy knight — attacks with the power of light and supports the party with Lugard's Blessing
Set party	Crusader + Illusion Knight + Rage Fighter

He also borrows part of the Dark Knight kit — Twisting Slash, Rageful Blow, Strike of Destruction, Blood Storm and Charge.

The Crusader's Skills

Skill	Requirement	Effect
Divine Fall	STR 60 / AGI 29	A hammer manifested from Lugard's light falls from the sky, damaging enemies. No cooldown.
Holy Sweep	STR 420 / AGI 168	Advances forward while swinging a hammer enlarged by Lugard's power, striking everything in the way. No cooldown.
Sacred Impact	STR 1,045 / AGI 418	Hurls a hammer of light for up to 8 hits, including repeated hits on the same enemy. The thrown hammer is rendered as the hammer you actually have equipped. No cooldown.
Lugard's Blessing: Punishment	Level 220 · ENE 200	Summons Lugard's emblem — the skill attack power of you and party members near the emblem is increased. No cooldown.

The emblem aura is his signature mechanic — a stationary party buff zone that makes him a strong anchor for a group, on top of his own heavy melee damage.

His armor runs Leather → Brass → Iron Plate → Solid early, then the full mastery chain from Blood Angel (Lv 400) to Lightning (defense 522–539) and finally the Temple Guard Crusader Legendary set:

Helm — 604	Armor — 622	Pants — 619	Gloves — 598

All Crusader armor sets

His armor runs Leather → Brass → Iron Plate → Solid early, then two socket sets, the full mastery chain, and finally the Legendary Temple Guard set. Every mastery tier comes as a 5-piece Excellent version and a 4-piece Set version:

Set	Pieces	Excellent defense (helm/armor/pants/gloves/boots)
Trust (380 socket)		54 / 62 / 59 / 52 / 53
Saint (400 socket)		68 / 80 / 74 / 67 / 68
Dark Angel		127 / 146 / 142 / 121 / 122
Holy Angel		181 / 200 / 196 / 175 / 176
Soul		230 / 247 / 244 / 224 / 227
Blue Eye		279 / 296 / 293 / 272 / 275
Silver Heart		327 / 345 / 341 / 321 / 324

Brilliant		424 / 442 / 439 / 418 / 421
Apocalypse		473 / 490 / 487 / 467 / 470
Lightning		522 / 539 / 536 / 515 / 518
Temple Guard (Legendary)		547 / 565 / 562 / 541 / 544

All Excellent tiers share the same requirements: helm STR 734 / AGI 335, armor STR 886 / AGI 382, pants STR 797 / AGI 350, gloves STR 660 / AGI 314, boots STR 692 / AGI 319. The Set versions add mastery options and a rising Triple Damage Rate — 2% at Soul, 4% Blue Eye, 6% Silver Heart, 8% Manticore, 10% Brilliant, 12% Apocalypse and 14% at Lightning.

The Temple Guard Crusader set needs the 5th class change and level 1,500. Its 4-set gives mastery critical and excellent damage, ignore enemy defense +9%, crit and excellent rate +20%, triple damage +16%, mastery max HP, damage reduction and mastery ability-skill attack. Pairing it with the Temple Guard Hammer and Paladin Shield unlocks the Legendary Full-Set: Extra Critical +5%, Extra Excellent +5%, Extra Double Damage +3%, Extra Additional Damage +4%.

2nd Legendary – Progenitor's Imperial

The new top tier. Imperial gear sits above the Temple Guard Legendary line and requires level 1,600. Every Imperial weapon shares the same option block: excellent damage rate +10%, attack/magic speed +7, life and mana on kill, +3.6 attack per 20 levels and a flat +102 attack.

Imperial armor is a 4-piece set per class at level 1,600, with defense around 630–680 per piece. The standard set options are: 2-set mastery skill attack + main stat; 3-set double damage +18% + mastery attack or magic; 4-set mastery critical and excellent damage, ignore defense +9%, crit and excellent rate +20%, triple damage +18%, mastery max HP, damage reduction and mastery ability-skill attack.

Legendary Full-Set bonus (Imperial armor + matching Imperial weapon set)
Extra Critical Rate +5% · Extra Excellent Rate +5% · Extra Double Damage +3% · Extra Additional Damage +4% · Nuke +150 / Bolt +100 / Wide +50 attack power

Imperial set	Render	Weapon set for the Full-Set bonus
Imperial Knight		Imperial Sword ×2 (Conviction build uses Conviction Sword + Imperial Shield)
Imperial Wizard		Imperial Wizard Staff
Imperial Elf (Agility)		Imperial Bow + Imperial Quiver
Imperial Elf (Energy)		Imperial Fairy Shield
Imperial Magic (MG)		Imperial Magic Sword ×2, 2H Sword, or Magic Staff ×2
Imperial Lord		Imperial Scepter + Imperial Lord Shield

Imperial White Wizard		Imperial White Wizard Staff + Magic Book

Two sets deviate from the standard options. The Imperial Knight (Conviction) build trades offence for a tank profile — VIT +520, defense +360, crit and excellent rate +60%, Solid Blessing party attack +380 and shield defense +292. The Imperial Elf (Energy) support build gets defense enhancement +75%, attack enhancement +63%, Bless enhancement +95 and max HP +670, with a full-set bonus of elemental attack/defense enhancement and +300 healing effect.

The Crusader's Imperial set arrived in Part 2-3:

Helm — 655	Armor — 673	Pants — 670	Gloves — 649

How to craft Imperial gear

Imperial Anvil — 160,000 Ruud	Imperial Soul — 80,000 Ruud	Imperial Enhancement Stone

Imperial gear is not dropped — you upgrade your 1st Legendary Temple Guard items. Both recipes are 100% success:

Item	Base material	Special material	Jewels	Zen	Rate
Weapon / shield	+15 level, stage 5 Temple Guard weapon or shield	Imperial Anvil — Priest James, 160,000 Ruud	Bless ×30, Soul ×30, Creation ×1, Chaos ×1	500,000,000	100%
Armor	+15 level, stage 5 Temple Guard armor	Imperial Soul — Priest James, 80,000 Ruud	Bless ×30, Soul ×30, Creation ×1, Chaos ×1	200,000,000	100%

Weapons keep their stat, Luck and weapon options; armor keeps its stat and Luck options. The result starts again at level 0, stage 1.

Enhancement path	Materials	Rate
Normal	Imperial Enhancement Stone ×12 + Bless ×1, Soul ×1, Life ×2, 10,000,000 zen	50% (up to 70% with a Luck option and Charm of Luck)
Elite	Shining Imperial Enhancement Stone ×12	60% (up to 80% with Luck and Charm of Luck)

Imperial gear uses the same level 0–15 × stage 1–5 system as Temple Guard, and is never destroyed on failure — so no Chaos Combination Charm is needed. Imperial Enhancement Stones drop in Aquilas Temple; the Shining version is a cash-shop item.

Aquilas Temple

Lore: the Kanturu people built Aquilas Temple to worship the Eagle God, using technology beyond other civilisations. Their faith began pure, with offerings of sheep and cattle — but as Kundun's infiltration destabilised the world it curdled, and they began sacrificing the clouded-souled experimental creatures they had made. Unknown energy pooled in the temple. A subordinate of Kundun found it, opened a dimensional gate, and summoned a legion of eagle phantoms that slaughtered every Kanturu inside — they believed the eagles were gods and could not fight back. The entrance was sealed; centuries later the seal weakened, and Priest James now sends MU's warriors in.

Map	Entry	Enter Lv	Penalty Lv
Aquilas Temple	Move command (50,000 zen) or the entrance at Kanturu Ruins (124, 171)	1,600	1,650

Aquila Warrior — Bolt	Aquila Gunner — Nuke	Aquila Magician — Wide

Monster	Level	Extra type	Behaviour
Aquila Warrior	1,050	Bolt	Melee — strikes up to 2 characters in range
Aquila Gunner	1,050	Nuke	Ranged — attacks up to 5 characters
Aquila Magician	1,050	Wide	Ranged area attack on up to 5 characters

It drops Imperial Enhancement Stones (the key material for the whole Imperial tier), Imperial Excellent armor, Ability Crystals and Temple Guard Soul Crystals. Its elite zone was later removed when the Forgotten Raklion elite zone opened.

Forgotten Raklion Elite Zone

Giant Mammoth — Nuke	Giant — Bolt	Iron Knight — Wide

Elite monster	Level	Extra type	Behaviour
Forgotten Giant Mammoth	1,110	Nuke	Melee attacker
Forgotten Giant	1,110	Bolt	Area attacker
Forgotten Iron Knight	1,110	Wide	Ranged area attacker — drains AG and MP from those it hits

Attribute	Entrance	Debuff it applies
Fire	221, 219	Bleeding + attack power decrease
Water	238, 44	Deadly poison + attack power decrease
Earth	240, 145	Bleeding + attack speed decrease
Wind	18, 138	Deadly poison + defense decrease
Dark	25, 60	Bleeding + defense decrease

As always, elites apply their debuff at 100% chance on any hit, share boss immunities, and can only be resisted with a Guardian's elite resistance option. Their exclusive drops (weekly capped) are Sealed Armor Fragments, Elite Guardian Enhancement Stones, Elite Option Change Fragments, Golden Emblems, Garuda's Flame, Uriel's Feather and Jewels of Harmony.

8th Guardian – Rhino

Rhino — Lv 1,500	Rhino (Rare) — Lv 1,500

Options	Values
Base	Movement speed increase · Attack speed +7 · Defense +476
General (1–3)	Elemental attack +433 · Elemental defense +433 · Defense +8.0 per 20 levels · Attack/Magic/Curse +8.0 per 20 levels
Elite resistance	One of five attribute types, as with earlier Guardians

Rhino's Seal — 50,000 Ruud	How to get it: upgrade-combine a +11 or higher 7th Guardian (Tauros) at the Lorencia Tamer (122, 110) with a Rhino's Seal (Priest James, Elbeland 32/239, 50,000 Ruud) plus Bless ×20, Soul ×20, Chaos ×1, Creation ×1. 100% at +15, then 90 / 80 / 70% and 60% at +11. Failure consumes the materials and drops the base Guardian to +0; success re-rolls its options, with a low chance of the Rare version.

Deep Dungeon Renewal

The Deep Dungeon was retuned to be usable much earlier, and its punishing mechanics were stripped out:

Floor	Entry level before	Entry level after
Floor 1	770	730
Floor 2	770	750
Floor 3	770	770
Floor 4	770	780
Floor 5	770	780

Change	Detail
Monster scaling	Monster stats and the EXP they give now scale to your entry level
Penalties removed	The hunting penalty inside Deep Dungeon is gone, and the debuffs from Larva, Poison Bull Fighter and Thunder Lich were removed
Penalty rules elsewhere	Hunting penalty now applies in all class-change states (1st through 5th) and whenever the monster level is 275+ — with Deep Dungeon floors 1–5 as the only exception

9th Mastery Earring – Benevolence Earring

Benevolence Earring (Right) — Lv 1,100	Benevolence Earring (Left) — Lv 1,050

The Benevolence Earring is the 9th and highest mastery earring, following Wrath → Ancestor → Honor → Blood → Enchantment → Bond → Verdant → Frigid. Wear the matching left and right pair to activate the set option, and enhance to +15 with cutting stones from the Chaos Goblin.

Earring	Req level	ATK / Magic / Curse	Elemental defense
Benevolence Earring (Right)	1,100	568–571	556
Benevolence Earring (Left)	1,050	528–531	498

Side	Random options (1–3, scaling with enhancement level)
Right	Max Mana +1,000 · Excellent damage rate +12% · Critical damage rate +12% · AG auto-recovery +10 · Attack speed +7
Left	Max HP +1,000 · Skill attack power +33 · Mastery attack/magic +163 · Mastery excellent damage +275 · Mastery critical damage +275

Set bonus (both equipped)
Ignore enemy defense 9% · All stats +12 · Mastery damage +110

How to craft it

Benevolence Cutting Mold — 25,000 Ruud	Base: a Frigid Earring (8th mastery) at +11 to +15. Material: Benevolence Cutting Mold — Priest James, Elbeland (32, 239), 25,000 Ruud. Jewels: Bless ×20, Soul ×20, Chaos ×1, Creation ×1. Where: the Chaos Goblin. Left upgrades into left, right into right; options re-roll to 1–3.

Frigid Earring level	+11	+12	+13	+14	+15
Success rate	60%	70%	80%	90%	100%

As with every mastery earring, taking the base Frigid Earring to +15 for the guaranteed 100% is almost always cheaper than gambling at a lower level. See the earrings guide for the full ladder.

Crywolf Rebuild

The new Enter button auto-moves you

Crywolf was rebuilt around modern levels and made far easier to actually join:

Change	Detail
Elemental monsters	Crywolf monsters are now elemental. Every Thursday one of Fire, Water, Earth, Wind or Dark is picked at random and held for the week — check it on the Crywolf screen of the Event Map & Boss Battle UI.
Rebalanced	Monster stats retuned so the event is recommended for level 1,000 characters. The boss Balgass now has debuff immunity.
Notification & auto-move	A notification icon appears at the top-left during Crywolf time. Click it to open the integrated UI, then hit Enter to be auto-moved to Crywolf — available to characters level 1,000+.
Rewards	No longer dropped on the ground — now delivered through the Gremory Case with a 7-day claim window.
Schedule	Altar registration moved to Monday 09:30, and Balgass now spawns 6 minutes 40 seconds after the battle starts instead of 10 minutes.

The mission briefing	Progress panel	Result & ranking

Outcome	Effect
Success	Monster HP −10% across the server until the next Crywolf siege, plus a Rank/EXP score and a ranking table
Failure	All NPCs inside Crywolf are deleted until the next siege

The mission itself is unchanged in spirit: defend the Wolf Statue. Only Fairies can contract with the altar and channel power into the statue, so the party has to protect them while they hold the contract.

Monster Soul Converter

The converter tiers were re-pointed at Season 21's level curve. Each tier takes souls from a specific monster list:

Converter	Recommended level	Required monster souls
[Lv 1]	400+	Destray, Berserker Warrior, Urk Devil Fairy, Nars Devil Fairy, Dark Mammoth, Sapi Queen
[Lv 2]	800+	Feria Knight, Paraka, Cyclops, Skeleton Warrior Captain, Thunder Lich, Swamp Ent
[Lv 3]	1,150+	Mine Digger, Bahamut of the Abyss, Scorched Warrior, Crimson Alkamos, Temple Ogre, Ashen Destray
[Lv 4]	1,250+	Crimson Lycan, Underground Persona, Magma Gladiator, Bloody Mutant, Storm Guard
[Lv 5]	1,500+	Twisted Crypta, Devil Sword, Shadow Master of Destruction, Aquila Warrior

Buy a converter from Priest James, kill the listed monsters to fill it, then convert it for reward items. See the Season 14 guide for the original mechanics.

Everything Else in Season 21

Max level rose 1,700 → 1,750, and both the Lv 1,650 and Lv 1,700 season rewards could be claimed — each giving a Muun with ×20 base ability for 30 days:

Alchemist — Lv 1,650 reward	Crusader — Lv 1,700 reward

Muun	From	Base ability
Alchemist	Reach Lv 1,650	Skill attack power +15
Crusader	Reach Lv 1,700	Elemental defense +10

Update	Details
Upgrade costs	Drag-and-drop upgrading with Bless and Soul jewels was removed. Zen costs were added for +1 to +9 and raised for +10 to +15 — from 300,000 zen at +1 up to 4,500,000 at +15.
Event map levels	Entry grades were rebalanced — Chaos Castle, Blood Castle, Devil Square and Doppelganger now run to grade 7 (1,600+), and Illusion Temple to grade 5 (1,600+).
Boss Battle Together	Boss level raised to 110 with HP up to 145,690,000 and attack, defense and elemental damage all increased.
Energy Elf fix	The Elemental Defense buff and its upgrade option were recalculated — the Energy stat now contributes more, the upgrade option slightly less.

FAQ

Where can I play Season 21?
Browse the Season 21 private servers listed — this is the newest season, so most servers running it are fresh.

Is the Crusader good?
He's a durable frontline with the highest starting HP of any class, heavy hammer damage scaling through Combat Power, and a party buff aura in Lugard's Blessing. Sacred Impact's 8 hits make him strong single-target as well as in groups.

Do I need Temple Guard gear before Imperial?
Yes — Imperial is only made by upgrading a +15 level, stage 5 Temple Guard item. There is no other source, so the Season 20 Legendary grind is a hard prerequisite.

Where do I farm Imperial Enhancement Stones?
Aquilas Temple — it's the only drop source, and you need 12 stones per enhancement attempt at 50%. The Shining version from the cash shop raises that to 60%.
