Latent Effects
From Revival Ragnarok Online
What are latent effects?
Latent effects are effects which are not always active and occur randomly by chance.
While you are free to discuss the latent effects among yourselves, there will be no officially published specifics on what latent effects are. They are also subject to change, so any information you or other players obtain may change. Please do not ask staff about latent effects as they cannot tell you anything.
