Up to 14-20% Strength, scaling with Peril.

This is the build I use with a team as support/artillery. The constant knockdown and high damage are excellent for horde clearing and keeping elites on the ground. The Deimos is for single target, armor, and elites. With the Kinetic Deflection perk and Deflector blessing, you can also use it to get from point A to B safely. If possible, use brain rupture on heavy armor and snipers etc.
