Well, if dwarves would have some special armour or weapon only they can do, then each other race should have thier own item(s) only they could craft.
But then halfings, if they are both human and dwarf, i dont think they should be able to do both. Either they could be more dwarf than human and vise versa, or then halfings would have thier own item(s).
If so, then elves could have better bows, like power 1 bows, humans better swords and orcs something on for thier axes?
I also like the ideas for drinks and other stuff Jistuma noticed. But cati and water could maybe be poison? Or maybe cati+red muchroom+water could be poison?
