MU Online Season 11 Guide

Season 11 (2015-2016) opened Feria, the ruined kingdom under Tarkan, and handed out a new skill to almost every class. It added the Blood Angel weapon line, upgraded the Archangel's Absolute Weapons with a unique buff skill, pushed seed spheres from level 4 to level 10 with a rebuilt socket workshop, introduced four new pentagrams, and bolted on quality-of-life features: the hunting record, camera zoom and the Mine Finder minigame.

Feria, the sunken kingdom

Feria was an artistic kingdom that fell into a dimensional rift during the Great Earthquake of Tarkan. Its knights still patrol the ruins. Entry needs character level 400, either from the map move window or from the Tarkan safe zone at (176, 38).

Two gate pairs move you around the map: the red gate links (198, 173) with (107, 67), and the blue gate links (201, 155) with (199, 137).

Knights, Fighters and Archers each come in all five elements. The General is not a field monster — he is summoned by the boss.

The Feria Lord boss fight

The boss zone entrance is at Feria (112, 60). Breaking the crystal orb inside summons the Lord and seals the entrance — nobody can enter or leave until the fight ends. The fight is over when the Lord dies or everyone inside is gone, and the next crystal orb respawns 12 to 24 hours later. The Lord drops 3 items on death.

New skills for every class

Season 11 gave new skills to the third-class and second-class characters alike. The spell books and orbs are sold by the Ruud shop NPC, Priest James. Every one of these skills carries a main element, so it benefits from skill imprinting, and every one has a 5% chance per hit to fire one extra hit.

Blood Angel weapons

The Blood Angel line finally got weapons to match the mastery armour. They are bought from Priest James in Elbeland (32, 239), and each one arrives as an Excellent item with randomly rolled options. Excellent damage rate +10% is always present, plus one or two more from the pool; Luck is also random. A three-option roll always comes out as excellent damage +10%, attack speed +7 and attack power +1.5 per 20 levels.

The Magic Sword also needs 139 energy. Weapon skills come attached: Twisting Slash on the sword, Power Slash on the magic sword, Multi-Shot on the bow, Force Wave on the scepter, Beast Uppercut on the claw and Thrust on the lance.

Archangel's Absolute Weapon upgrade

The old Absolute Weapons became upgradeable into Blessed Archangel's Absolute Weapons — higher stats, the full excellent option set, and a unique buff skill. You need a weapon at +15 with 16 option levels plus an Archangel's Hammer.

Celestial Steel drops from field bosses and boss fights, and anyone carrying an Absolute Weapon — plus their party members on the same map — can get it from ordinary monster kills.

Every upgraded weapon carries the same six excellent options — excellent damage rate +10%, attack/magic power +2 per 20 levels, attack/magic power +57, attack speed +7, and life and mana recovery of (stat/8) per monster killed — and the new skill Archangel's Will: a buff that gives you and nearby party members +200 PvP attack damage and +50 skill attack power.

Socket system expansion: spheres to level 10

The Seed Researcher was removed and the Chaos Goblin no longer handles 400 sockets: all six socket combinations live in one window at the Seed Master in Elbeland (46, 243) — socket item upgrade, seed extraction, seed sphere synthesis, mounting, extraction and the new sphere upgrade.

Seed spheres used to stop at level 4; they now go to level 10. You upgrade one by registering the sphere plus a second sphere of the same level and Sphere Upgrade Runes, whose count rises with the level. Even on failure the main sphere keeps its level and options — only the sub material and runes are consumed. Extraction was also improved: you now get the seed sphere back with its level and options instead of a plain seed.

Sphere options by element

The Earth sphere is new and is the only one that raises stats. Three option types were also rewritten: attack power per level became per 20 levels, max HP/mana became a flat addition instead of a percentage, and HP/mana on monster kill now restores exactly the listed value.

Bonus socket options

Mounting spheres in the right elemental order still creates a bonus option, but the payout now depends on the level of the spheres you used.

Option caps

Season 11 also put ceilings on the options everyone was stacking: excellent damage rate 70%, critical damage rate 80%, damage decrease 60% and shield defense increase 1800%. Anything above the cap simply does not trigger.

Because these combinations replaced the old ones, Sphere and Tetra items and the 400-socket materials (Sonic Combination Note, Ice Walker's Mane) no longer drop — anything you still hold can be sold to a shop. Repair costs for weapons and armour were also reduced.

New socket items for Rage Fighter and Grow Lancer

The two newest classes finally got their own socket gear, and the new socket item upgrade converts the 380 versions straight into the 400 versions, keeping Luck, skill and socket count.

Dropped socket items now print their socket count in the drop tooltip (so the MU Helper's selected-item pickup can filter on it), and hovering a socket item in the inventory shows the level of the spheres mounted in it. Raklion was reshuffled at the same time: monster spawns moved, 400 socket armour no longer drops there, and Selupan gained Blast Break, Horn of Steel, Magma Sphere, Devil Cross Crossbow, Spite Staff and Ambition Shield.

New pentagrams and elemental changes

Errtel rank-ups became far friendlier: combine two errtels of the same type at rank 1 level 7 and you get a rank 2 errtel at 100%; the same again at rank 2 level 7 gives rank 3. The errtel in the left slot keeps its options; the one on the right is consumed. An Elemental Conversion Talisman, bought with zen from the potion shop during events, changes the element of a pentagram or errtel at 100% while keeping level, rank and options — it will not work on a pentagram that still has an errtel mounted, or on the Errtel of Radiance.

Existing pentagram options were rebalanced so they activate far earlier — several options that demanded an Anger errtel at rank 2 level 3 now trigger at rank 1 level 0, and the rank 3 level 5 requirements dropped to rank 3 level 0. Beginner characters also got their own kit: a Beginner's Pentagram plus four beginner errtels (Anger, Blessing, Integrity, Divinity) giving +1 elemental attack, +1 elemental defense, +1% elemental attack rate and +1% elemental defense rate, and +5% pentagram attack and defense when all four are equipped.

Character information window

The character window (C) was rebuilt. Specialisation values now print under each stat instead of hiding in a tooltip, and stats are split into two colours: permanent stats in yellow (levels, fruits, master tree stat nodes) and variable stats in light blue (from equipment and buffs). The distinction matters — item and skill requirements must be met with permanent stats alone.

Shift + C opens the extended window, which finally lists everything the game had been hiding: critical, excellent and double damage rates, ignore-defense rate, reflect chance, skill attack power, damage increase and decrease, absorb, automatic HP/mana/AG/SD recovery, recovery on monster kills, full-recovery chances, mana and AG cost reduction, SD ratios and SD ignore rate in PvP, stun rate and resistance, base defense from Steel Armor, shield block and weapon block rates from the master tree, and zen acquisition rate.

A new Element tab shows your equipped pentagram, the summed elemental attack and defense from its errtels, your skill imprint bonus and — most usefully — your attack and defense affinity against every opposing element, sorted with the elements stronger than yours at the top and separated into PvE and PvP columns. Carrying a Fire pentagram against a Darkness opponent, for example, applies a 110% attack affinity.

Hunting record, Mine Finder and camera zoom

The hunting record logs what your MU Helper does: one row per day per hunting ground with hunt time, normal and elemental damage, healing, monsters killed and experience. It keeps 60 days and drops the oldest row after that. Open it with the icon at the top-left or the End key; today's row is highlighted and updates live, and any column can be sorted. Minimise it and it switches to a per-second readout you can watch while hunting. Tick share my hunting record and other players can open yours with Alt + right-click → view hunting record.

Mine Finder runs on Card Pieces that drop while hunting (tick "event item" in the Helper to pick them up automatically); 24 pieces make a Card Bundle and start a game. Click a square to reveal how many of the eight surrounding squares hide bombs — the first click is always safe — and right-click to flag one. Score comes from the numbers you open, with penalties for wrong flags and for stepping on a bomb, plus a clear bonus. Claim the reward and a graded box lands in the Gremory Case (K), where it stays for 1 day.

Zoom is disabled in a few places, including Imperial Guardian and Battle Soccer, and resets to the default view whenever you change map.
