MU Online Season 14 Guide

Season 14 is not a season you read about and move on from. One of its additions is a class on your character creation screen, another is the only equipment in MU that runs out of battery while you wear it, and two of its maps are the corridor from level 850 to 1,030. This guide sorts it into what a Season 22 player uses, what later seasons buried, and what costs you upkeep forever.

The short version of what 2018 shipped

Season 14 arrived in two parts and did five jobs: the Rune Wizard, taken to a 4th class change; two new rungs on the mastery ladder, Soul weapons at level 900 and Frigid Blue Eye armour at 1,000; Kubera Mine and the three floors of Atlans Abyss above it; a Summoner split into two switchable builds; and Guardians, wearable items with a vitality meter, plus the elite zones that justify them.

The question on a Season 22 server is narrower: which parts you touch, at what level, and what sits on top now.

The Rune Wizard, because she is a live choice

The Rune Wizard is a decision you make before you have a character at all. She is the daughter of an Arca wizard and a fairy, raised in the half-elf village of Iria until the Lemuria Legion razed it on the march to Crywolf. What matters mechanically: energy-based magic, a rune mace and a shield, and spells built to be stacked rather than fired one at a time.

The shield is the part people misread. She is not a glass caster holding one for show: her gear budget covers a weapon and a defensive slot, which is why she survives inside what she clears.

Her class changes run on the usual schedule, except the 4th, which is a quest.

Three spells and two buttons, and that is the whole kit

Attacks and buffs are usually two lists. One table plans better: energy gates the spells, level gates the buffs, both self-only.

Fifteen seconds up against a sixty second cooldown is a 25% window, so Burst and Haste are boss tools. The rotation: Plasma Ball to open, Magic Arrow as filler, Lightning Storm on cooldown past 500.

The enhancement tree is where her damage stops being about gear: each branch feeds one spell and can hang a debuff off it.

Her weapon ladder is the only progress bar you need

Nine maces, four kinds of item, one list, sorted the way you acquire them. Wizardry sits before attack power because on an energy class it decides your damage.

The absolutes ask very little for their attack power, so they bridge the gap while you are short of energy, and the Blessed Absolute beats a Dark Angel mace on wizardry with no level requirement at all.

Shields are borrowed rather than bespoke: she equips the Elf's socket shields, the Frost Barrier and the Light Lord Shield.

Armour, and where her ladder joins everyone else's

Her sets start class-specific, then join the mastery ladder every class climbs, so from level 400 her gearing is a Grand Master's. Each step is a 100% Chaos Goblin upgrade from a +11 / 16-option piece plus that tier's Ruud-shop material.

The Wings of Destiny close the class out. As 4th wings they roll 1 to 4 random options plus 0 or 1 elemental option. The caption numbers are fixed; the roll is what you reroll for.

Level 900 and level 1,000: two walls that are still walls

This part is neither class-specific nor optional: reach for the top of a Season 22 server and you stand at both gates.

Both run at 100% at the Chaos Goblin, and both want 30 Bless, 30 Soul, a Jewel of Chaos and a Jewel of Creation. No gamble, so the real cost is the +11 / 16-option base.

All Soul weapons share one excellent block, so the table is only numbers and requirements: excellent damage rate +10%, attack speed +7, life and mana recovery on kill, attack or wizardry +2 per 20 levels, and +57 attack power.

Grouped by role: melee weapons want huge strength for middling attack, the Elf's two pieces want over 1,100 agility, and the caster sticks look weak until you notice they multiply wizardry rather than add damage. On our Season 22 server the 32,700 stat cap makes these requirements far less of an obstacle.

Frigid Blue Eye is the bigger step. Its mastery options scale with the item's enhancement level — mastery max HP, skill attack power, strength, agility, energy and all stats — and set bonuses reached five pieces for the first time. Read it upward: the 5-set line is why anyone finishes.

One footnote belongs to the Grow Lancer alone: its absolute weapon landed here. The Archangel's Absolute Lance is 115–126 attack with no level requirement, and at +15 / 16 options an Archangel's Hammer plus 30 each of Bless, Soul and Life makes the Blessed Archangel's Absolute Lance, 173–184 attack with the Archangel's Will buff.

Kubera Mine to Atlans Abyss: one corridor, levels 850 to 1,030

These two maps ship as separate features and are not: they are one stretch of levelling route, back to back, and what you plan around is the entry levels and the penalty bands above them.

Kubera Mine is the first mine on the continent, abandoned after Kundun's followers prayed at its altar. It splits into the mine and the harder abandoned mine, joined by five elemental field gates, with a safe zone where you can swing a Pandora's Pickaxe. Atlans Abyss is the seal built to hold Hydra, and it runs three stacked floors.

Both drop excellent Blue Eye armour. The Abyss adds a catch: everything there carries excellent damage rate resistance, critical rate resistance and 4th-tree debuff resistance, so builds leaning entirely on crit or debuffs lose output.

Eleven monsters in one block by level instead of two tables. The band is tight, 380 to 460, so what gates you is the entry requirement and the resistances.

Guardians: the only gear in MU with running costs

Guardians change your habits rather than your numbers. They are inventory items for level 800 and above, equipped with a right-click, granting ordinary options plus what nothing else gives: elite resistance. They enhance to +15, and their vitality drains the whole time you wear one — at zero it unequips itself, and a Jewel of Bless refills it.

That last clause is why Guardians feel broken to new players. Nothing is wrong; the bar ran out mid-grind. Keep a Bless on the character.

Two NPCs run the system: Moss sells the box, the Tamer does the rest.

The enhancement row deserves fear: a failure at +10 or above does not cost a level, it wipes the Guardian to zero, and the stone gets dearer at that point.

As a mount the Ghost Horse is exclusive with Uniria and Dinorant, though a Dark Lord keeps his Dark Horse. It carries attack speed +7 and a movement bonus, 1 to 3 normal options (defense or attack per 20 levels to level 1,100, elemental attack, elemental defense), and one of five elite resistance sets.

Elite zones, and what they do to you

Elite zones are the other half, and the reason the resistance stat exists. One sits inside the current top hunting ground, flagged on the map. In Season 14 Part 2 that was Atlans Abyss floor 3, with (Elite) Abyssal Lizard King and (Elite) Abyssal Bahamut. Season 22 sits well above the Abyss, so read that as a pattern, not an address.

Elite monsters land their debuff at 100% on every hit and are boss-immune to yours, and only a Guardian's elite resistance blunts what comes back. Which element you need maps cleanly to what it takes from you.

Four things drop there, and two feed systems from other seasons, which is why elite zones outlived their launch floor.

If you play Summoner, Season 14 is the season that defined her

This section applies to one class, and it matters because the Summoner on a Season 22 server is structurally the one Season 14 built. She was split into two builds, selected with a buff that holds until you die or disconnect.

Each buff is fed by the stat the other build uses, which is what catches people building her.

The skill rework aged best. Explosion, Requiem and Pollution came off the Otherworld Book to become parchment skills with far shorter animations and cooldowns, their damage-over-time converted to normal damage, which is what made her an attacker. Weakness and Innovation became magic circles centred on her, and the master tree can add enemy elemental attack and defense reduction.

Death Scythe is her signature here: not a cast you aim but a thing you summon that follows you, so it opens a pull rather than finishing one.

Her books follow the same four mastery rungs as everyone's weapons: eleven points of curse power a step, requirements that barely move.

Two option changes came with them: the wizardry option on excellent Otherworld Books is now curse power, and on mastery armour it reads wizardry / curse power.

Three ways Season 14 still pays you

Strip out the class and the maps and what is left is income: a second mastery earring, a Ruud item that turns kills into loot, and a level reward.

The Ancestor's Earring is the second mastery earring, made by upgrading an enhanced Earring of Wrath with an Ancestor's Refining Mold from the Ruud shop plus 20 Bless, 20 Soul, a Jewel of Chaos and a Jewel of Creation. It rerolls your options, and failure costs the materials and drops the earring to +0.

The sides are not interchangeable: the right doubles the fixed line and rolls rates and speed, the left rolls flat mastery values. Wearing both from one season adds ignore enemy defense 2% and all stats +5.

Enhancement level on the base is the whole gamble.

The Monster Soul Converter, and the Thursday deadline

Priest James sells Monster Soul Converters: carry one, kill the monsters it names, then right-click it and choose a reward category. Souls count for your whole party, you hold one at a time, and purchases are capped weekly. The trap is the clock: an unfinished converter expires at the Thursday maintenance, when the list also rotates. Finish it and it becomes permanent.

Each conversion pays one guaranteed and one random item from the category you pick: Ruud (400 guaranteed, 200 to 4,000 random), jewels, elemental items such as runes, pentagrams and errtels, or accessories. Only the level 5 converter rolls accessories, and it is the one source of Earrings of Wrath outside Mos.

The cap moved from 1,100 to 1,150, and reaching 1,100 before the next season paid a box: 30 days in the Gremory Case, 14 once withdrawn, holding the Archmage Etramu muun, elemental defense +10, running at 20x for 30 days and wearable next to a premium muun. That reward is closed; the ceiling is not. Later seasons raised the cap again, so read 1,150 as the Season 14 line — Season 15 picks it up there.

The client changes you stopped noticing

Most players use several of these daily without knowing where they came from. SWITCH mode is the headline. Ctrl + F drops the client into a low-resource view that still reports your helper state, level and experience, zen, and free space in your inventory, event inventory and personal store, refreshing the screen as a still image at your chosen interval. It can start itself after an idle period, and if you run several clients it is the biggest thing here for you.

The jewel stacking row changed how MU is played rather than how it looks: fifty to a stack is why bulk trading is routine, and why our custom jewel system is worth reading before you hoard.

What to actually do about Season 14

• Pick the Rune Wizard for a caster who can stand in the pack, build energy, and save Burst and Haste for a boss.
• Do not skip the absolute maces. A Blessed Absolute at 80% wizardry outlives the mastery steps people rush toward.
• Treat 900 and 1,000 as the real milestones; both upgrades are 100%, so the cost is the base item and the Ruud.
• Keep a Jewel of Bless on any character wearing a Guardian, and stop enhancing it at +10.
• Buy the level 5 converter if you want accessories, and finish it before Thursday maintenance.
• Do not plan around Atlans Abyss floor 3 as the elite zone; that flag moves.
• Press Ctrl + F before you complain about client performance.
