I hope someone with more experience chimes in, but I think it is important to recognize that trying to shoe-horn object oriented paradigms like inheritance is destined to fall short in Elixir. Inheritance just is not part of the language by design.
I would recommend you define behaviours for your “object classes” and then have each specific module implement the behaviours it requires. So a sword can implement weapon behaviour, and a shovel can implement weapon behaviour and tool behaviour and so on.
