May the best win

The Player vs Player arena is not the main focus on Luna Obscura, but we know some players will just want to solve their issues with a "fair" fight.

Damage is reduced while in PvP compared to regular PvE environments
Skills and items individually will not have PvP-specific changes applied.
PvP is to be seen as an extra activity, not the focus of the game.

Proper large scale fights can happen in the Rhapsody Castle during specific moments in Luna Obscura, but for when you want a smaller fight, you can visit the arena in Nocturne.

Colosseum Arena: For duels 1v1, a small area to fight with proper timing and setup.
Underground Arena: For open PvP fights, free for all or with parties, no rules enforced free to fight.

Both can be accessed for free.
