After an adventure with my father Quilly, we made it to the scary (and huge) Ra'Kaznar Inner Court. I posted some screenshots of our adventure recently, and I was asked how to get there. So here we go!
(Admire my epic Paint skillz)
-- The Red Line shows the way to the Silvery Plate KI (which you need to access Inner Court according to FFXIcylopedia).
-- The Blue Line shows the way to Ra'Kaznar Inner Court after obtaining Silvery Plate KI.
1) Head down the first vine to the 2nd map.
3) Hop onto the platform here to get a small cutscene, and the KI.
4) Head down the vines here for a shortcut.
5) Last vines to scale down before the zone.
2) Colonization Reive. First one you need to defeat.
6) Colonization Reive after the last vine is scaled down, before entering Inner Court.
Your aim is to reach the east elevator on Map 2. Bare in mind that Ra'Kaznar Inner Court has no waypoints, so get Ionis before the journey, and if you are attempting to do the RoE objectives, you should bring a friend or two along.
We were able to defeat the Acuex and Gargoyles, however the Byrgen are BAAAAD. They are powerful, spam entomb (like a more powerful breakga) and nukes the hell out of everyone. Trust NPCs will drop fast to them. If you see Byrgens, you are quite far in.
There are strong mobs in the area, such as Vampyr and Dvergr. We were able to duo the Vampyr (THF, DNC and trusts) with difficulty. Happy Hunting!
