Since we are entering the last stage of building Gracia Final update let me hint you with more news before official release
This update will include inside all chronicles fixed so you will get full fixed (Interlude, Hellbound, Gracia pt 1, Gracia pt 2, Gracia final), so all things that didn't work so far or they did work but totally wrong or custom made they will be fully off. working and fixed.
All things that you knew about l2 forget it, and start learning how things will work. If you find things that work differently (correct) from a previous version don't report it instantly as a "bug", make sure you followed all official instructions about it (quests, skills , raid path,etc...)
As some of you already heard , i will confirm it now, we will start this mega update 1st on Valkyria x9 server they will get 1st the update itself, after tests , error reports etc... we are planing to update whole network (don't ask ETA on this cause it all depends of the Valkyria so it can be short if stability is on required level) but more about it when we actually up it.
So since we are near download the required client (its in loader) and prepare yourself for upcoming update, and once again my ADVISE to all DN players to start reading official site how things works , else you will be quite lost, in the end you have to read past 4 years of updates. I will try help you with 1 link that i found useful , so make sure you get informed on time:http://www.lineage2media.com/guides.html
Have fun and cya soon.
