Body Trapped in Dvergr Town

I just started out in the Mistlands and it was going okay. I found my first Dvergr Crate in the bottom of a castle thing; down some spiral stairs. There were two mages down there, and being naive, I thought if I ambushed them quickly enough, I could kill them and I'd be okay. Well, they smoked me, and now my good armor is stuck down there. I went back with my previous set of Wolf Armor, a backup shield and Frostner, and died again. They've blown up the stairs, and the splash damage from their attacks even kills me through the floor. I have no good armor left. It's all fucking stuck in a pit with two mages who one-shot me. I tried throwing blob bombs down there, but they destroy those too. I have no idea how to get my shit back... anyone have any ideas?

Edit:

Apparently the mages blew up the ward themselves. I was able to build a workbench and a stonecutter nearby and I started digging and disassembling around the outside of the tower. Eventually I was able to get a decent angle on the two mages and shot them with my bow a few times and killed them and got my loot. Thanks to everyone for the ideas.
