Witch King on Fell beast 325

Total: 2225

I know castellans aren't supposed to be that great but I love the models and with all the other targets I'm presenting to the enemy they might just make it through. The Witch King is a large investment at 325 but again I love the model and I think he'll make his points back being a flying monster. The Betrayer is to go with the crossbows and provide me some cover for my assaulting monsters and Morannon Orc masses.
