This build focuses on a very comfy play style that is not reliant on substantial enemy density to keep going.

The basic rotation involves shooting to proc [Growing Power] > cast 4 to strip armour > cast 2 to group > breach surge > shoot > everything is dead > recast magnetise to detonate (optional).

You can either helminth of her 1 or her 3 for breach surge. Personally, I prefer to helminth off her 1 since her 3 keeps ally shields up, strips shields, acts as a nice buffer to her 4 and can be used to break containers.

If you don't have a max arcane resistance, you can drop magnetised discharge for [Rolling Guard]. Note, if you are fighting a faction that doesn't have toxin procs, you can change out resistance for an arcane of your choice (molt efficiency and augmented are good choices).

You can swap energise for steadfast if you prefer. Additionally, if you are running zenurik you can swap energise to any arcane.

If you do not have [Primed Sure Footed], swap it for [Handspring], [Power Drift] or [Cunning Drift].

[Archon Stretch] can be dropped for regular [Stretch] if you aren't going to be using a companion that can proc it i.e. [Diriga] and hound. Do not use augur mods on [Mag] since they will reduce the duration of your shield gate.

134% strength is needed to full strip on [Mag]'s 4 in 1 cast. You can achieve this without strength shards if you use [Precision Intensify]. [Corrosive Projection] can be used if you don't have [Growing Power]. [Transient Fortitude] can be used instead of [Umbral Intensify] if you want to save on shards and forma.

Archon shards: 2x tauforged red strength shards (at least 1 tauforged required for full strip on her 4 in 1 cast) 1x blue energy shard or 1x [Equilibrium] shard and 2 x tauforged casting shards.

Why boreal + max fleeting instead of 1 from top fleeting + 1 from top [Streamline]? Duration is a semi worthless stat for this build, and the extra shield capacity gives a nice increase to recharge delay if you somehow run out of energy. Additionally, if DE ever fixes the bug were overshields affect shield gate duration this will allow you to get close to the max shield gate (2.5s at 1,150 shields).

Edit: further refinements over the past 9 months:

Energy is really not an issue on this build so swapping energize for arcane impetus gives you more strength and allows you to use a 1 from the top [Fleeting Expertise] or you can replace fleeting with [Streamline] if using a hound companion.

If you aren't using a [Pharaoh Predasite] or hound modded for blast toxin save a forma and use primed instead of [Archon Continuity]

Pyrotechnics does some pretty crazy damage on ragdoll grouping abilities like pull. If you don't want to use this you can swap pull or your 3 for breach surge, blood altar, koumeis helminth, silence or nourish.

Arcane hot shot can be replaced with whatever arcane you like.
