This guide comes from the old wiki and is being reviewed; some details may be out of date. The Codex always shows the current game data.
Introduction
The Kugan System, inherited from the previous Mystic Project servers, is one of the most important aspects of your playing experience. It allows you to add a whole new potential for your character.
These can vary from magic spells to melee attacks, the goal with these new abilities is to create ways to play never seen before on Ragnarok Online!
Kugans can be viewed in the Kugan tab, in the Skill windows. They are not limited: your character can have as many Kugans as you desire, as long as you have the required points. Furthermore, abilities drawn from Kugans aren't job-locked and can be used with any job.

Classic Kugans located at the Midgard Library
How to learn a Kugan?
To obtain a Kugan, head to the Midgard Library, in Midgard City. The Library is also available through the Quick Access System.
Click on the according Book to visualize the full Kugan list. Each Book represents a type of Kugan:
- Active Kugans grant an active Skill. They bestow powerful and complex benefits at the cost of SP/LP for a short period of time.
- Passive Kugans grant a passive Skill, you don't need to use it to benefit its effects. They give benefits related to statistics, damage or resistance.
- Passive Signature Kugans also grant a passive Skill. They offer more complicated effects, in order to improve the synergy with your gear or other Kugans. Currently, a character can only get one Signature Kugan.
