This question already has an answer here:
I'm DMing a Pathfinder game with all new characters and I'm not very experienced as well. We are all learning a lot each session and the players are happy to change things when we learn we've been breaking rules.
Anyway, I have one player (dwarf barbarian) that has been adding teeth, horns and other pointy animal-parts from their quarries to his greatclub. So far I've allowed him to treat his greatclub as bludgeon and piercing damage, and after adding so many, we are now treating his weapon as masterwork.
He's very attached to his club and I know as we progress, he'll prefer to continually upgrade it as opposed to replacing it. What are some ways he can continue to upgrade his weapon that won't end the weapon's progression? Our cleric is getting the Craft Magic Arms and Armor feat at his next level, and the party has been talking about enchanting things but from what I've read so far enchants seem more on the permanent end (I'm totally fine with being wrong).
