Is dual wielding The mage staff named Y'yter Durr worth it?

I found two of those right now and I don't even know if this weapon is really good. Has anyone tried it out? What does that staff even do? Should I use them instead of 2 highly enchanted scimitars?

It gives you polymorph status as well as polymorph control, so dual wielding it wouldn't give much other than another weapon I guess?
It's a double edged sword in my opinion since it would raise the danger level quite a lot (if you choose to polymorph into something strong), so if you don't have good enough gear it could be more dangerous than advantageous.

Thanks for the quick answer, I guess I will sell one of them.

Alternatively it would probably make an excellent sac option if you need to curry divine favor.
