EMPTY SLOT FOR GALVANIZED REFLEX

[Ceramic Dagger] transforms into Incarnon form after using heavy attack after reaching 6x combo. Gun and Blade and Adept Reflexes evolutions give 120 initial combo after 100 kills which is equivalent to 7x combo. Adding Galvanized Reflex to this gives you permanent 11x combo (or 12x with [Ready Steel]). Heavy attacking while incarnon mode is active throws a projectile with approximately 5m AOE with forced impact and innate heat status. You can make gas electric or blast electric to proc influence OR if using Volt/[Shock Trooper] you can mod pure blast or pure gas and rely on external electric to proc influence.

This is specifically for using the incarnon heavy attack projectiles to kill enemies. Grouping + armor strip is ideal to make this scale, otherwise the damage isn't very good against armored enemies. Armor strip can be applied by Amalgam [Argonak] passively or actively through warframe abilities.

At the time of testing, Condition overload works while Sacrificial Pressure/[Primed Pressure Point] DO NOT seem to apply any damage to the projectiles. Once it works, [Primed Pressure Point] is flexible over [Condition Overload]. Ability based damage buffs like Vex Armor, [Rift Torrent], Eclipse seem to work fine.

UPDATE
Melee Influence + Amalgam [Argonak] makes this even stronger for AOE nuking, at the cost of a bit of crit chance. You must slot three elemental mods to force blast/gas + electric due to the innate heat on the projectile.

EVOLUTIONS:

Evo II: Gun and Blade : 100 IC after 100 primary kills (secondary kills work too atm)
Evo III: Adept Reflexes 20 IC makes final combo 150 after 100kills + corrupt charge, giving you permanent 8x heavy attack multiplier (but requires about 2-3s to recharge)
Evo III: Absolute Dominion: +30% SC gives you as base status of 50%. After [Weeping Wounds] and status chance mods you hit 330% status chance.
