My main defensive [Mag] build. Very good for mobile defense & extractors.
Magnetize an enemy then cast your 3 to turn their armor & shields into shrapnel. All bullets both friend and foe will be pulled into the bubble as well. When used with weapons with very high or infinte punchthrough like the Nataruk, it makes an enemy blender capable of killing large groups of enemies quickly.
Cast your 4 to reapply shields to your entire team & self.
Recommend running 2 amber archon shards with casting speed to make the build easier to use.
