Season 10 to Season 15

Almost every update in this era raised the maximum level. The dates are when each update went live on the Global servers, taken from Webzen press releases (Korea got them earlier, see Timeline). For the current cap see Level Cap & Season Rewards.

Season X Part 1 & 2 (7 April 2015) introduced the Grow Lancer, the third female class after the Elf and the Summoner. She fights in melee with a lance, and depending on her stats she can lean towards physical or elemental damage, which suits both hunting and PvP. The update also opened the Asgard server and Nars, the fifth region of Acheron, where the boss Core Magriffy drops pentagrams and new mount Muuns (Repen, Pawn, Grippus) can be found.

The same update added Tormented Square (Battle) and an event map square that gathers the NPCs of Chaos Castle, Blood Castle, Devil Square, Illusion Temple, Doppelganger and Fortress of Empire Guardians. Event maps began giving Mastery Boxes with Ruud, a new currency spent only at Priest James's Ruud Shop. Season X Part 3 (1 September 2015) added the fifth Errtel, Errtel of Radiance, for a pentagram's fifth slot, and the Skill Imprint system, which strengthens skills that match the pentagram's element.

Season 15 Part 1 (14 July 2020) opened a Speed Server where the 10th character, the half-human, half-bat Slayer, could be played first. On 11 August 2020 the Slayer came to all servers, together with the new map Scorched Canyon and the level 1,200 cap.
