there is an option to add to this a tracking skill, so you won't have to run around with luck you find your prey, but rather follow some tracks.
How? well, this may work like a compass to a nearest animal, but not on straight line, but rather a path, which you may slowly find out as you walk.
And i see a mayor problem with you idea. Everybody does, but you could learn till now..
When you are going to increase value of something, it is always because something else was raised before. Always So instead proposing to increase value of some animal parts, propose value of what should be decreased, so thet your idea will work.
If not, soon we shall pay 10,000,000,000,000 for a crafted short sword.
