Class renewals and new classes

  • Grow Lancer (July 2024): her first renewal since her 2015 release. New skills Oversting, which calls one Grow Lancer per target to stab each one, and Wild Breche, a lance swing that hits everything around her, plus exclusive Mastery Lancer Shields from Bloodangel to Brilliant.
  • Dark Lord (January 2025): new Ruud skills Spirit Blast (area damage) and Divine Force (raises the stats of party members), exclusive Mastery Lord Shields, and upgraded pets Divine Spirit and Divine Horse. Command was later added to his Skill Enhance Tree.
  • Alchemist (July 2025): a new magic class that can be created from the start and begins its journey in Elbeland. It fights with a Wand and an Elixir, mixes damage with support, and can summon extra field monsters to speed up hunting for the whole party. Its skills are Angel Homunculus, Ignition Bomber, Countless Weapon and Confusion Stone.
  • Rune Mage (February 2026): a full renewal of the rune-wielding Half Elf with an exclusive Mastery Shield, new explosive rune skills that hit an area, balance changes and a new Wizardry Power stat.
  • Crusader (July 2026): a hybrid class with a hammer and a shield that uses the power of light both to deal damage and to strengthen allies, built for solo and group play.

Each of these launches came with a Speed Server. From 2024 on a character earned 100 Ruud per level from 401 to 800 (40,000 in total), each account got one free transfer to an original server, and reaching level 800 before moving unlocked a bonus that included +13 [Bound] 3rd wings and 350,000 Ruud. In Season 21-1 the Speed Server was rebuilt as 'Reborn': its cap rose from 800 to 900 and Deep Dungeon became available there.

5th class and Lv.5 wings

The last update of Season 19-1 (September 2024) brought the biggest step of this period. After level 1,200 a character can finish three quests from the NPC Eunice to complete the 5th Class Advancement. This unlocks the Extra DMG types Nuke, Bolt and Wide, which work once the matching Extra Ability Card sits in an Ability Upgrade Core.

  • Ability Crystals drop from monsters in Burning Kethotum and harder maps, and are crafted into Skill, Option and Elite Ability Cards.
  • Another quest from Eunice after the three advancement quests gives the Giant Mount, an armored two-legged walking robot that adds +20 movement speed.
  • Lv.5 Wings (capes), the first new wing level since 2018, are crafted from a Lv.5 Wings Divine Object, an Ultimate Magic Crystal and Zen. A Wing Core adds visual effects and extra bonuses.
  • An Ultimate Magic Crystal is crafted from Mastery set items at +9 or higher with 16 or more options, and each craft gives 3 crystals.
