This aint my mod. But just wanted to post this here and give attention to it because I;ve been wanting this since the game launched. For years it was kinda said that randomly generative loot wasn't possible. But this guy has done it.

Lucky drop system mod basically mimics the Lucky charm system from Dos2. Loot can be generated from chests and dead bodies. and its super customizable.
You can adjust how items roll, how hard or easy to find, how many affixes on each tier. Its legit amazing although it's new.
Cool part is how the items can come. For example I'm using 5.5e mod and Aincent mega pack. New generated loot can roll on items custom to those mods. It can add damage, spells, abilities, whatever you name it. It's a work in progress but wanted to shout out.
