Currently, we are set to the episode 11.3 with some QoLs request from others episode. That means that we have accepted some suggestions from the community such as slot enchanter from episode 12 just to name him.
In general, we strictly follow item implementations according to their episode. For example, if you are looking for a Siroma card or a Rogue Treasure, it is not available yet.
It is a specificity that we have decided to assume and we will continue to follow this path until we reach episode 13.2.
We update the server episode every 6 months, we think it is the best compromise between grind and the start of boredom after few months of implementation. So you have always a few things to do in Spirit Online!
To finish, we can say we are pretty "vanilla" experience although we have some features. We think official RO experience is not the best and we have modified some things to improve the game we all love.
