Hello guys! 
As you know me (or maybe you don’t), I am quite experienced with the mod and have been playing it for thousands of hours till now (over three times as much as I’ve played the base game per se). Based on the RoT discord chat that I’m active on (beginners, frequently asked questions, etc.), I have decided to spend the last few days planning out a loot filter for the mod! Though technically it is a rainbow filter, yes, it is different in regards to being specifically designed to distinguish items by rarity, quality and type instead. I welcome everyone to discuss possible improvements in my discord DM (raksokekw). That said, here below is a picture list of features:
Should you want to download this is a link for the loot filter with regular item texts in brown colors:
text_en.zip (111.2 KB) RoT version (0.7.6.3)
This is the link for the loot filter including rainbow filter for stats inside the item:
text_en.zip (135.9 KB) RoT version (0.7.6.3)
(Please notice the colours for stats are slightly altered compared to the default rainbow filter, as they include a larger margin of powerful stats unused by the base game, arbeit present in the mod, and those are highlighted by strong colours such as Indigo or Grayish Magenta)
Unzip and drop the folder to:
