Forsaken Follower has a pretty good HP to Nora ratio and with her Pawn and Summon skeleton she is pretty tanky for her cost. the minor heal she can throw out is nice as well. Wretched Witch has some nice uses but I find that for her to really shine you have to build the bg around her. She is pretty cool with a Hex doll but it makes her expensive.
