is there sub to main option change in this server? i cant find it anywhere..

If you want to change your sub class (when Fate Whispers and Mimir's Elixir are done) come to nearest Grand Master, choose "Subclass" or "Сабкласс" (on Russian) and choose one of the variant (add, change, delete). Then choose sub. List of sub classes differs for every Grand Master (depend on race)

If you want to change game lang print .cfg and choose EN

Sry for my bad English =)
