Dawnguard Sentinels (max) [18]

You need to make sure to have two waves of Sentinels. The first wave goes in and starts doing damage while the second one is there to make sure the feat is potent.

You can change the Manticore and Sylys for a Phoenix to give you a model to deal with high defense and a better threat range as well as an Arc Node for Stranglehold, it's really up to you.
