I like a lot of what you have going here FS. I don't think every creature has to have a weapon or maybe they can drop similar parts to ones that already exist. Alternatively I like the idea from scorpions to maybe have the new creatures drop enhancement materials that can be used to add buffs to existing gear like adding poison dmg/resist bye crafting potions to be applied like the witcher or other games have done. This would boost the utility of the potions stations and encourage players to craft more items to hold in inventory. It would also be cool to have some o them craft larger backpacks for more storage space as well.
