With the theme of Darkwood as is it, I ran across some interesting real life species of mushrooms and fungus, some of which could have a direct relation as gameplay implements. Thought they obviously could be redesigned and given new names.
Hydnellum pecki; a fungus with red pigment secretion, while it is not edible, it contains anti coagulant properties, as you can bleed in the game, could be a fairly common consumable
Cordycep parasitoids, but maybe crossed with somthing else disgusting like botfly larvae, or the infamous mango worm.
(if your faint of heart or have a weak stomach, take my word on the mango worms)
My other suggestion was maybe include a bladed melee weapon such as a sword or bayonette attachment for ranged weapons, with the eastern european style I wanted to suggest a sister saber or russian shaska.
