Netmarble opened its first special server, 'Zero,' for 'Raven 2' on the 27th, coinciding with the game's second anniversary. 'Zero' offers higher experience gain and equipment drop rates compared to existing servers, and players can earn the paid currency 'Crystals' through gameplay. New rules include combat balance adjustments, simplification of tiers for castles, familiars, and weapon resonance, and a ban on PK in hunting grounds. The new class, Warlord, has also been introduced. The Warlord is a melee class conceptualized as a battle commander who dominates the battlefield, primarily using a spear. Players can change their existing class to Warlord through a class change event and receive related rewards, such as a Warlord growth support box.
