This build works wonders with a [Miter] as your primary weapon.

In summary, your primary attack and defense is your ability 2: Magnetize. Simply cast it on any target, charge [Miter] and shoot anywhere into the bubble. Magnetize will automatically pull everything in its radius towards its center and will headshot its primary target and continue to damage everything in its path as it frantically rotates through and around the center. The more damage you deal with this the more damage will result in the explosion when you pop the bubble. I have easily achieved 1 million damage with the initial hit from [Miter]. Magnetize deals 25% of damage absorbed as blast damage plus its base explosion damage. (Yes, the damage you deal will count as this bonus.) Generally, I see numbers between 120k-300k to everything in its radius when I pop it.

Generally speaking, you should not be dying regardless of the mission as long as you are able to cast magnetize. If either you or the enemies attacking you are within the bubble, you are (mostly) safe from damage. I say mostly because if you have multiple groups targeting you from different areas of the map, and you are not within the bubble, you can still take damage. That is easily avoidable by either being closer to your target so that you are within (or on the opposite side of the bubble from the enemies) so as to actually absorb the damage. Moreover, you can simply cast magnetize on both parties and clear the entire room, your choice.

We do not care much for efficiency as most things die absurdly quick and you are [Mag], so you can bullet jump near your energy orbs to pick them up very efficiently. Especially if you are running zenurik focus there is no need for saving energy as you will have more than enough unless there is an energy leech. For missions that you expect to have reduced energy or an energy leech I would recommend to replace [Augur Secrets] or [Augur Reach] with [Primed Flow]. I personally prefer [Augur Secrets] since the extra range is very valuable.

I personally equip [Mag]'s Arcane Coil Helmet to increase all ability range by 25% with a drain of ~25 shields and taking an arcane slot. The trade-off is easy for me since I rarely find myself reliant on an extra arcane slot and the range is extremely valuable.

Links to other builds that I use with [Mag] and of course the primary weapon which synergizes extremely well will be included as I complete them.
