MU Online Season 16 – Gun Crusher, Arnil Temple & Ashen Aida

Season 16 (2020–21) added the Gun Crusher — a magic-gun gunner, the first ranged class of his kind — with his own elemental skills, guns and armor. Around him came two maps (Arnil Temple, Ashen Aida) with full monster rosters and elite zones, the 4th Mastery (Blood) Earring, the 3rd Guardian (Pierce Lion), a Magic Gladiator renewal, the Silver Heart 6th weapons and the Roar of Manticore 7th armor. Rebuilt page-by-page from the original patch notes.

The Gun Crusher

Gun Crusher character art MU Online
The Gun Crusher — key art

Story: to turn the tide against Kundun, the MU Empire secretly founded an Imperial Corps and abducted a healthy orphan boy, Fisher, for brutal training. His eyes always burned brightest — he passed the ordeal but lost his sense of self, becoming a soldier loyal to the Empire. Named the Gun Crusher, his first mission — exterminate the monsters — sends him to Elbeland.

The Gun Crusher's Skills

His kit is built around elemental Magic-Gun fire. The first three are bought from Marse in Elbeland, the next two from James (Ruud shop):

SkillElementWhat it does
Dark PlasmaNoneFires a plasma orb at a target or spot; it stays put and damages nearby enemies every 0.5s for 5 seconds.
Ice BreakWaterSends ice forward for a hit, then the shattering shards deal a second hit.
DeathfireFireA very-fast fan-shaped barrage that pours damage into a cone of enemies.
Ice BlastWaterHits everything around him, freezing the ground where it lands.
Bursting FlareFireA strong front hit plus a shockwave around him — enemies caught in both take extra damage.
Fixed Fire (buff)ENE 300, from Marse. Toggle buff — drops a little defense but raises attack speed and magic power. Master nodes boost both further.

Arnil Temple

Arnil Temple map MU Online Season 16

Lore: a colossal temple built in the ancient empire to worship the vampire god Arnil (Lemuria). Priests who were demons in human guise deceived the continent into worshipping an evil god, then gathered half its people in one place and slaughtered them as a sacrifice — awakening Arnil, who became Lemuria and resurrected the sealed evil god Sekneum (Kundun). The ruined temple is now a base for Kundun's remaining underlings.

It's an attribute hunting ground (monsters resist excellent/critical damage) and drops Excellent Manticore armor. Its elite zone has five attribute wings (Fire/Water/Earth/Wind/Dark), each applying a 100% debuff on hit, and drops the materials for 4th wings, Blood Angel armor and Guardian enhancement.

Ashen Aida

Ashen Aida map MU Online Season 16

Lore: deep in Aida, lingering dark magic drained the colour from the land, plants and beasts — turning them black and white. Named Ashen Aida, the continent's heroes came to purge the dark magic within.

4th Mastery Earring – Blood Earring

Blood Earring right MU Online
Earring of Blood (Right) — Lv 850

Earring of Blood (Left) — Lv 800

The Earring of Blood is the 4th mastery earring, after Wrath → Ancestor → Honor. Wear the matching left + right pair for the season set bonus; enhance to +15 at the Chaos Goblin.

EarringReq levelBase options
Earring of Blood (Right)850ATK / magic / curse 238–241 · elemental defense 226
Earring of Blood (Left)800ATK / magic / curse 198–210 · elemental defense 168

Set bonus (both worn): ignore enemy defense +4%, all stats +7, and a new Mastery Damage +60. How to get it: upgrade a +11–15 Honor Earring at the Chaos Goblin with a Blood Jeweling Frame (Ruud shop, Elbeland 32/239) plus Bless ×20, Soul ×20, Chaos ×1, Creation ×1 (100% at +15 down to 60% at +11).

3rd Guardian – Pierce Lion

Pierce Lion (Rare)

The Pierce Lion is the 3rd Guardian — an inventory-equipped mount at level 1000, with a rare, differently-coloured variant. Guardians also gained a new base Defense option this season (retroactive to the 1st and 2nd Guardians).

How to get it: upgrade-combine a +11 or higher 2nd Guardian (Ice Dragon) at the Lorencia Tamer (122/110) using a Seal of Pierce Lion (Ruud shop, Elbeland 32/239) plus Bless ×20, Soul ×20, Chaos ×1, Creation ×1 (100% at +15 down to 60% at +11). A successful combine re-rolls its options and can rarely yield the rare version.

Magic Gladiator Renewal

The Magic Gladiator was reworked into three distinct builds, each with its own persistent charge buff (bought from the Loren mage Pashi) and signature aura skills:

Each charge stays on until death or logout. The new and renewed attack skills (all from Priest James in Elbeland, 1,000 Ruud) build around them:

Gigantic Storm (renewed)MageLightning over a wide area — normal damage count raised from 1 to 2.

New Magic Two-Hand Swords arrived across every tier — Blood Angel (400) → Dark Angel (600) → Holy Angel (800) → Soul (900) → Blue Eye (1000) → Silver Heart (1100, 790–840 damage). Knight-type AG costs were cut (Blood Attack 20–24→12, Fire/Ice Blood 28→14), agility now gives more attack speed, and the master/skill-enhancement trees were reorganised around the charges (each charge's Mastery adds an extra aura-explosion/Nova on the 3rd trigger).

Silver Heart Weapons & Manticore Armor

The Silver Heart weapons are the 6th mastery weapon tier — one per class, all requiring level 1100, all sharing the Excellent line (+10% excellent-damage chance, +7 attack/magic speed, life/mana on kill, +2.4 per 20 levels, +68 attack). Made by upgrading a +11 (16-option) Blue Eye Excellent weapon with a Silver Heart Anvil (James in Elbeland, 100,000 Ruud) + Bless ×30, Soul ×30, Chaos ×1, Creation ×1 — a 100% combine that keeps the weapon type, Luck and Excellent options.

Above them, the Roar of Manticore set is the 7th mastery armor (level 1200) — made by upgrading a +11 Silver Heart armor with a Manticore Soul (James, 50,000 Ruud) + Bless ×30, Soul ×30, Chaos ×1, Creation ×1, keeping class, slot, Luck and All-Stat options. Most classes get 5 pieces; MG and Rage Fighter get 4.

Pentagram – New Opposing-Attribute Option

Pentagram opposing-attribute option MU Online Season 16 gave every Pentagram a new default opposing-attribute attack / defense option that grows as you enhance the Pentagram — a big boost on the attribute maps, since it targets the element your Pentagram counters.

Mastery Pentagrams also gained attribute-option slots (one per Wrath/Guardian/Sacred slot, up to 3), filled by combining Errtel items — each Errtel type grants its element's target attack or defense option (you can't duplicate the opposing-attribute option or an existing one).
Your PentagramOpposing-attribute option (attack & defense vs.)
Fire PentagramDark-attribute targets
Water PentagramFire-attribute targets
Earth PentagramWater-attribute targets
Wind PentagramEarth-attribute targets
Dark PentagramWind-attribute targets

More on the system: Pentagrams & Errtels guide.

Gem of Harmony Renewal

The Gem of Harmony system was reworked so Harmony options no longer depend on your item's enhance level, and the combine can't fail:

BeforeAfter
Option valueTied to the item's enhance levelSame regardless of enhance level
Options given1 random option, can fail1–3 random options, no failure

Values now roll in a range across four tiers, shown by option colour: Low / Mid (white), High (blue) and Top (pink) — e.g. STR +10, +15, +20, +30. Assigning, removing and refining (now "refine-stone crafting") are all handled by the Jerin and Osbon NPCs in Aida.

Details: Harmony options guide.

Bound Mastery Chaos Combine Amulet

Mastery Chaos Combine Amulets MU Online
The bound Chaos Combine Amulets, one per mastery tier

A new bound (non-tradeable) Chaos Combine Amulet in six mastery tiers — Blood Angel, Dark Angel, Holy Angel, Soul, Blue Eye and Silver Heart. When you run a +10 to +15 enhance combine on the matching mastery-tier armor or weapon, the amulet prevents the item from being destroyed on failure (in exchange for a 5% lower success rate). Its fragments drop from certain hunting grounds — collect 5 fragments to craft the amulet for that tier.

Season Reward Muuns

Both max-level expansions came with a Season Level Reward box — reach the level cap before the next season, claim the box from your Gremory Case (30-day claim, 14-day box life), and drop it to receive an exclusive Muun. Each grants a small permanent stat plus a big ×20 base-ability boost for its first 30 days:

FAQ

Where can I play Season 16?
Browse the Season 16 private servers listed — the Gun Crusher ships in every later version too.

Is the Gun Crusher strong?
He's a ranged elemental gunner — Dark Plasma zoning, Deathfire cone spam and Ice Blast AoE make him a fast farmer, and Fixed Fire adds attack speed and magic power. Energy is his key stat.

What's the endgame gear path?
Blue Eye → Silver Heart weapons (6th mastery, Lv1100) and the Roar of Manticore armor (7th mastery, Lv1200), plus the Blood Earring and the Pierce Lion Guardian.
