Build Details:
Ability Efficiency isn't necessary with [Equilibrium] + Dispensary, allowing us to dump efficiency in order to boost other stats, such as duration and strength. If energy issues arise, you can swap out Stretch for Primed/Flow.
Durability and survivability comes from shield gating with Shield Satellites (default Hold 1, recommend using inverted toggle option found in settings). [Rolling Guard] is optional, but highly recommended as it provides a safety net useful for uncomfortable situations as well as quick status cleansing.
Overextended + Stretch gives us a massive range of 50 meters on our Blaze Artillery and a more forgiving pick-up radius on our Shield Satellites.
Roar is the recommended subsume for a [Blaze] Artillery focused build as it "double dips" on DoT procs like heat in addition to increasing our ability damage. This boosts our artillery damage even higher and is instantly noticeable at higher levels. [Archon Vitality] is chosen for a similar reason and not for the health bonus it provides. While the extra health is useful for dealing with toxin damage (which bypasses shields entirely), the primary reason we take this mod is to double the heat procs produced by our artillery. This provides a tremendous boost to their damage output, allowing our artillery to scale well into the thousand level range in Steel Path.
More strength and duration is always nice to have on [Protea], so Molt Augmented and Molt Efficiency are easy picks. Not only do they both increase the damage potential of our artillery, but they also increase the amount of shield regen provided by Shield Satellites and the chance of double pick-ups from Dispensary.
For Archon Shards, I recommend one for Duration and the rest for Strength. Eventually, with full Tauforged (if willing to invest further) you'll have over 300% Duration and 284% Strength (384% with passive). This gives you a nine second [Blaze] Artillery with a 50 meter range and a +115% damage Roar, which makes for disgustingly efficient results. It's not uncommon to see Heat ticks for multiple millions of damage.
