The idea behind this setup isn't to be monstrously powerful, but to be something that someone who doesn't have a fully built up mod collection yet could obtain with just a little grinding and not to much endo or to many formas. it also has some inbuilt survivability from the Augur mods, but you could easily sub in more standard defensive mods, such as [Vitality], [Redirection] and [Steel Fiber], adding a forma if needed, if you are having trouble obtaining some of them from Cetus. If you have an Exilus Adapter, go ahead and add whichever one feels good and fits. [Power Drift] works great, but would require a forma, if you want to add it, I would forma the aura slot to match.
