how does it look? should Redi's staff stay a staff or become a sword?

Personally I would have it so he can break his staff in half yo make smaller weapons and would have him keep sections on him so he can make into a longer weapon or use as ammunition (only arrows since those can be reused) or say the smaller sections can be used as armor

Sord

It would be cool if he could shift it into different weapons instantly

For example an axe or a dagger depending on the situation

It should be able to shift between them
