This is a VIRAL HEAT build taking advantage of the HUGE status chance from elemental balance and base heat from incarnon evolutions allowng you to stack up heat and viral status quickly.

Pair this with HEAT INHERIT and ARMOR STRIP for extreme scaling to levelcap.

If using a viral heat primer or a priming pet, you can swap out [Malignant Force] and [Rime Rounds] for [Hammer Shot] and either [Bladed Rounds], [Primed Shred], [Thermite Rounds].

For SLASH BUILD: Consider using Primary Merciless, and swap [Serration] for [Hunter Munitions].

For FUNNY GAS meme: Swap Rime Rounds for Hammer Shot, Primed Shred or Galvanized Scope to make pure Gas, or add Tox + Electric to make Gas/Electric. Best paired with GROUPING and ARMOR STRIP. (swap [Rime Rounds] for [Hunter Munitions] on [Zephyr] specifically).

BUILD BREAKDOWN

Mods
Galvanized Aptitude: Gives +80% damage PER unique status effect and is currently MULTIPLICATIVE to Serration/[Amalgam Serration] on incarnon form
[Amalgam Serration]: Gives +155% damage which multiplies with Galv Apitude AND +25% sprint speed which helps activate +80% fire rate from Deadly Pace evolution
[Galvanized Chamber]: Gives +80% multishot at base then another +150% multishot after 5 kills for a total of +230% multishot
[Critical Delay]: Increases incarnon mode crit chance to +150% without Vicious Promise

Arcane
Longbow Sharpshot is multiplicative to BOTH Galv Aptitude and Serration (+300% after headshot). This is flexible for Primary Deadhead or Merciless.

If you use Deadhead/merciless as base damage, you can drop Serration for Hammer Shot or Bladed Rounds.

EVOLUTIONS

EVOLUTION I:

• Deadly Pace - Use with sprint speed boost or fast warframe with sprint speed > 1.2 to get +80% fire rate, which frees up a slot on [Paris]. Sprint speed boosts include the Sprint boost aura, Rush mod, Speed Drift mod, Amalgam Serration (usually enough on most base 1 sprint speed frames), Praedos/Innodem perk. Warframes that have base 1.2 sprint and higher BEFORE any mods/perks include Ash, Baruuk, Ivara, Mirage, , Nezha, Nova, Protea, Wisp, Zephyr, Loki, Gauss.

• Guardian's might is a good alternative but the Overshields condition is not always possible on many warframes.

EVOLUTION II:

• Ardent Trigger for even more fire rate OR Swift Deliverance for projectile speed. This is personal preference for quality of life.

EVOLUTION III - actually a bit of room depending on prefrence.

• Elemental Balance is actually very good because it boosts premod status chance to 80%. After Galv Aptitude, 60% status mods and [Bhisaj-Bal], we end up with 312% status chance, i.e. guaranteed chance to proc 3 statuses per hit. If you proc 2 heat and 1 viral per shot, you effectively double your heat proc damage as well as receive a 2x multiplier. Pick this for viral heat and pure heat builds

• Vicious Promise gives the most potential DPS, but may be inconsistent since many enemies may be already damaged by your companion or warframe abilities or teammates, meaning you often dont have the buff.

• Striking Succession gives up to +60 base dmg on top of the +20 from Deadly pace which just adds a small amount to the initial base dmg of 520 on incarnon form, basically for an 11% damage boost for 3s. This is not as good
