This hound is pretty powerful. This setup is my go too. Did not really mess with much but it works for almost everything I've done in the game. This week was no different. Just run vazarin for the quick revive because there is not a posture for you to keep them next to you. They will at death as if they desire it. [Medi-Ray] because of the modifiers and [Atlas]' EHP is quite high. If you don't have the EHP then its a flex slot.
