Criatura AcademyAn English resource for kRO Zero
Guides, Gravity's official game guide in English, every announcement translated, and a record of every patch — for the official Korean Ragnarok Online Zero servers, built from the game's own client files and Gravity's own posts rather than copied from other sites. Guides mark every fact with where it came from and when it was last true.

Guides
Written, sourced and kept current against the game data.
- Levels and EXP — How high each job can level, how much EXP a level takes, and every time Gravity has changed either — including the February 2026 adjustment that the official EXP table has not caught up with.
- Poring Village — A level 30–60 party dungeon west of Prontera, and the only source of two lower headgears you can enchant.
- Refining — Gravity publishes Zero's refine rates in two places and they disagree in 174 of 200 cells, every one of them in your favour.
