Light armour crafted from sturdy leather made from troll skin, including some bits of troll fur as decoration. May be worth making texture variants based on different kinds of trolls, i.e. a black version made from cave troll leather, a white version for frost troll leather, etc.
Flounder and Udderfish meshes and textures from TES3A, packaged loose. Both have basic anims but need death animations and ingredients. Both should be passive. There's an unused texture for a flounder eye ingredient as well. Also will need an esp made.
(Some of the flounder stuff says "halibut" but the ingame name should be Flounder)
