The appearances of the wizard staffs are, in my opinion very skewed and utterly broken. I'm a believer in uniformity when it comes to magical items, and I think that apprentice staffs should be simple wooden staffs, and only the more powerfull staffs should have vortexes and skulls that glow, I also disagree with the fact you can alter them freely at the moment.
So, my suggestions are...
1) Apprentice staffs, and staffs of similar low power, be changed in the toolset to a uniform simple wooden staff appearance. While keeping the more powerful staffs looking powerfull and intimidating.
2) To make magical staffs uncraftable.
3) Take a moment to consider what school of magic the staffs belong too and if there appearance is suitable or not.
