Instead of buffing strength, you now have maxed efficiency and just double or triple cast your abilities. Pull is one of the most powerful abilities in the game, able to CC in a large AoE, through walls, without having to target anything. Open up every encounter with Magnetise or Polarise, then two or three Pulls to ragdoll everything into the bubble. Crush if you need more shields.
Everything should be consistently CC'd. The only annoyances are magnetic procs which drain your energy, and toxins which bypass health. That's where the Arcanes step in.
Spamming Pull is also extremely useful for solo Interception missions. Solo Arbitration Interceptions aren't a cakewalk for anyone, but this build just needs to kill the Arbi drones and then everything falls into place.
MODS
[Primed Continuity] can easily be substituted for more ability strength if you so desire, but this build is more about casting for CC. Proper placement of Magnetise bubbles and Pulls to capture more enemies is already more than enough damage.
