For anyone like me who loves 75% of the bestial vampire with the giant stupid wing over his head I found a quick solution for you. You can cut the arm off completely take the shoulder off as well. Then you need to get yourself Storm Vermin arms. The ones holding the halberds. There should be an armored arm the halberds and another hand attached. Cut away the halberd and hand and you have an arm with a similar armor style to the left hand. From there you can put on a shield or dress up the right arm to look a little cleaner without any niks in the armor. After that if you want a really clean job do it up with green stuff, but it doesn't look to bad right now before I've started to pretty it up. It's doable for anyone who can use flat headed cutters. Really quick I just wish that the bits order system was still up for people without access to storm vermin arms.
