Is there a catch to retraining a staff?

[Chernabog]

A while back, I made one mistake distributing my skill points. I was going to retrain the weapon but before I did I had an idea.

For a year I've read on this fourm that "Desolation" sucks and is just for showing off to noobs at Fort Charles. However, I've never heard of anyone putting 5 skill points in it and seeing what it does. My guess is that it still sucks, but I have several skill points to spare and therefore thought about trying it out for a couple of weeks and then retraining my staff to get rid of it.

Is it truly as simple as paying 250 gold and then getting to redistribute all your skill points? No catch? I still have not mastered this pirate and do not want to permanently screw anything up with my staff. Thanks!
