A build made for Profit Taker (PT) hunts.

Main build, where you can find more information and link to the other builds

Useful notes:

• This build was made explicitly for a [Chroma] user, it does not feature any Damage mod like [Hornet Strike], because Chroma's Vex Armor provides it. If you still want to go with it, but note that the damage buff will be ~15% at Most
• Kuva Nukor has a Magnetic Progenitor. I would advise to have at least a 40% Magnetic damage Nukor for this fight
• This build focuses on dealing Radiation, Magnetic, Heat and Corrosive damage to PT's shields
• Secondary Dexterity is 15 platinum, at the time I'm making this guide. What it offers is 60% damage on melee kills, Holster speed and combo duration, which is not used (not by me at least). The additional holster speed helps in changing weapons, even tho the [Chroma] build already has [Vigorous Swap]. The 60% kill is what makes this build even better. The duration is 20 seconds which makes it Very easy to use in conjunction with Gloom. Everything that jumps at you is a free kill, bonus damage for both primary and secondary. In comparison with Secondary Merciless, which has Very low duration and needs a lot of kill to achieve max damage potential, this is a Far superior choice. On top of that, this arcane is practically replacing 2 [Hornet Strike] mod alone at 6 stacks (well, not really, but close enough), and Chroma alone provides damage equivalent to 4 Hornet Strike
• Galvanized Diffusion is used for killing a lot of enemies at once and gaining a nice boost in multishot for the Profit Taker shield phases
• [Primed Expel Corpus] is probably the best mod that can be used, since it's a 55% flat damage increase (unless there is a player with Rhino's Roar, the % from Roar is added to Primed Expel Corpus, and it will be the final value)
• Ruinous Extention is the mod I'm using in the fight, simply because it helps with shooting the shield from a distance, and gives a much wanted peripheral vision on the surroundings

If you would like to get a riven for it, I guess you can go for one with multishot, critical damage, fire rate
