Bubble Gun [Kompressa Prime] | Red Crit Enervate DPS | Blast Elec or Corro heat

Full DPS Kompressa mainly for single targets

MOD BREAKDOWN
• Hornet Strike: mandatory base dmg. Do NOT use Galvanized Shot since Kompressa is 90% AOE And Galv Shot does not apply to AOE.
• Galvanized Diffusion: mandatory for +230% multishot at max stacks
• Primed Target Cracker: mandatory critical damage but flexible for Magnetic Might if fighting Thrax/Eximus
• Lethal Torrent: optional fire rate + multishot. Flexible if running external fire rate e.g. arcane velocity, amalgam Furax, Reinforced Bond
• Pistol Elementalist: Boosts status damage from heat and also gives reload speed boost.
• Element mods:

BLAST ELECTRIC: Blast on Kompressa has a soecial interaction with Enervate allowing sometimes the crit chance to stack to tier 4 or tier 5 red crits. Blast and Electric both have an AOE component which further improves the AOE clearing of Kompressa. This is the best option for AOE trash clear. This works best along side Xata's Whisper subsume because currently, Blast status procs xatas whisper in a 5m aoe which increases the potency of a blast proc. This instance of Xatas whisper also triple dips faction mods so ideally equip the corresponding faction mod.

CORROSIVE HEAT : Primed Heated Charge contributes a large amount of raw elemental damage and procs heat status which deals damage over time and strips some armor up to 50% at 2s. Corrosive status strips armor and corrosive damage has a bonus against grineer. Kompressa is innate viral so we don't mod for viral here. This is the best option for single target DPS.

Exilus
You can leave this empty if you prefer or steal the polarity and move it to a main slot to save forma.

[Lethal Momentum] increases projectile speed
Ammo mutation or Trick Mag helps with the feel of maintaining ammo if you have ammo issues
FLEXIBLE OPTIONS
You can drop Lethal Torrent if external fire rate:

Primed Expel - maximises dps against a specific faction and double dips status dmg
Magnetic Might - maximises DPS against enemies with overguard Thrax/Eximus
ARCANE CHOICE
Secondary Enervate: boosts the low base crit chance by adding flat cc. Kompressa is special with Enervate because the bubbles have a delay and allow it to stack beyond what is normally allowed and hit red crits. Best paired with flat crit multi boosts like [Tenacious Bond] and Arcane Crepscular due to the low crit stats.
Secondary Fortifier: great quality of life as it steals overguard, and is also the strongest option against Thrax.
