Cast 2 on yourself, your companion, your allies and the defense object
Cast 3 in front of you/nearby to CC enemies and prime them to drop energy orbs when they die. Note if you cast it around an acolyte, their AI often turns off.
Cast 4 and press 4 again immediately to end expansion (you want enemies to be outside the wall)
Kill some enemies with your primary to proc arcane blade charger (your sentinel can do this too)
From inside the wall, cast 1 at the wall (either tap or hold depending on stat stick damage type - tap is preferred since it is faster to cast and doesnt prevent reloading) to nuke the map and build splinter storm stacks
Repeat 4 + 1 combo
Kill heavier targets/acolytes by stacking damage into splinter storm and just, standing near them.
Add in armor strip if possible to speed up kills (e.g. [Helios], Unairu, [Grimoire] with [Jahu Canticle], [Latron], or use Corrosive Heat on a primer).
Add a viral primer to speed up kills.

Helminths
Subsume over Spectrorage:

Nourish: Gives additive Viral dmg boost to Shattered Lash and gives energy multiplier which helps greatly with energy sustain. Drop Spectrosiphon for Rolling Guard/[Narrow Minded]
Dispensary with Equilibrium is another good option for energy sustain in mostly stationary missions like defense and mobile defense, or for camping in survival. Drop [Spectrosiphon] for [Equilibrium] in this case.
Eclipse boosts shattered lash damage witch feeds into both splinter storm buildup and mass vitrify explosion damage. Drop Spectrosiphon for rolling guard/[Narrow Minded].
Terrify: fullstrips at 167% strength, or 137% strength if running [Corrosive Projection]. Drop [Spectrosiphon] for more strength to hit the threshold.
Fireblast strips armor in AOE which helps splinter storm and mass vitrify do more damage to armored enemies. At 100% str, fireblast strips 75% and causes heat status which strips a further 12.5%.
Pillage strips armor/shields and provides shields to you

Archon Shards
Amber - 1 to 2 cast speed shards to make casting of mass vitrify smoother
Crimson - fill rest with duration shards so splinter storm lasts the longest
