To this day I can't remember if I've ever found Jolees Robes in TSL. I can remember that I always used a very unmodified version of the game on PC in the beginning, but I played well over 15+ playthroughs on my Xbox original before playing the game on PC.
The only method I knew of to get his robes at the time on Xbox original was spamming a save right before speaking to Fassa the docking master for Vogga on Nar Shaddaa. Upon completion of his pylon quest you receive an item that was possible to be Jolees Robes. I could never actually get his robes though.
I did try spamming the infinite hssiss glitch as early as possible a few times but I still wasn't able to find Jolees Robes. I also never found Malaks robes in TSL, but I was only really concerned with not finding Jolees Robes to be fair.
The one thing I didn't like about the random loot in TSL was having multiple Freedon Nadd Blasters in one playthrough, or other multiple unique items.
The last few playthroughs I've used on the PC version has had a lot of mods, and I've not actually concentrated on acquiring Jolees Robes, as I've had like 100+ mods installed.
Has anybody ever found Jolees Robes before? Or have I been unlucky?
