Modus Operandi :

• 2 always up (be carrefull, i don't know if it's a bug or not, but sometimes i die while recasting the power, i think it's because the power desactivate while recasting)
• Same for 4 (all your weapons deal viral damage, who can augment the damage of your 3 ; and you gain more energy from all source)
• Launch 1 on an enemy far away from your fellow tennos and let it spread (to gain up to +427% damage to your primary, +532% when molt augmented is fully proc)
• 3 for dash, and one shot enthraxed enemy (some unit need multiple hit, even with viral and enthrall, like stalker and such)

Helminth :

• Nourish : viral on weapons and more energy to compensate the low efficiency
• Roar : always good
• [Xata]'s wisper : double dip on incarnon devoring attribution

I choose to replace the 4 because it's good only at "low level"

Loadout :

you can swap anything (the primary and melee are more a lore thing)
