Allows the player to craft and temper fully functional permanent bound weapons and arrows. Can be crafted at any smithy for 2 filled grand soul gems and tempered for 1 grand soul gem at any grindstone. Fully compatible with relevant perks and most perk mods (bound weapons inherit perks both from conjuration and their relevant skill trees, one handed, archery, 2 handed etc.). These wondrously weightless Unbound weapons are unseen when not in use and can be given to followers.
Limitations: Cannot be enchanted. Their perk compatibility and visuals are applied via an enchantment in vanilla. Altering this would cause compatibility issues and I’m not sure the visuals even can be applied any other way.
They also don’t have inventory textures and the enchant effects disperse when sheathing the melee weapons, rendering them invisible while sheathed and being invisible or incorrect images in the inventory screen. This is purely visual.
