L2Xb Custom is a Lineage 2 High Five private server built around a PvE-focused, non-competitive experience. The server emphasizes character customization through its MultiSkill and Rebirth systems, allowing players to build unconventional hybrid characters not possible on official servers. It is designed for solo or casual group play, with automated farming tools to support progress even while offline.

The server starts at x10 EXP/SP rates, which players can further increase through the Vote Manager system and a custom bracelet item. The MultiSkill system lets players learn skills from other races and classes via an in-game Race NPC and Skill Shop. The Rebirth System provides a post-cap progression loop granting exclusive Rebirth Skills. A Scheme Buffer offers unlimited preset buffs valid for 10 hours, removing the need for buffer characters. The server features 19 or more custom armor and weapon sets, with enchanting allowed up to very high values. Autofarm and Autospoil are built in.

The server has an active Discord community with around 550 members. Players can acquire most content through in-game farming and vote rewards without mandatory purchases. The server is hosted internationally and caters primarily to players who prefer a relaxed PvE environment over competitive clan warfare. It is a niche server suited to players who want to experiment with cross-class skill builds in the High Five chronicle.
