3 build pathsHow builds work in RO3
RO3 keeps the classic job tree: Novice, then a 1st class such as Swordsman, a 2nd class such as Knight, a Transcendent class such as Lord Knight, and a 3rd class such as Rune Knight. On top of that, each line offers build paths: ready-made specialisations that decide which skills you learn and how far you level them. The class pages list every path's skills tier by tier, exactly as the game defines them.
