Joining Ryujin Allows you to build the kiosk for 10000 Credits anywhere, gives access to low rank legendaries, and all vendor inventories across the settled systems.
Completing the tower infiltration mission gives you access to rank 2 Legendaries
Completing the questline gives you access to rank 3 legendaries, and the starborn trader inventory.
It is structured like this to hopefully give some incentive to doing the Ryujin questline, and “balance”.
I did try and add an amazon like subscription service to the mod via the kid stuff trait, but I just ended up breaking the script for kidstuff and had to scrap it.
