Hello and welcome to the tenth chapter of the Metronomicon!

In this chapter we will take a look at [Octavia]'s signature secondary weapon; Pandero Prime!

(Check out chapter 8 for a Octavia build that focuses on utilizing her signature weapons)

No matter what or how you build [Pandero Prime], you will always want [Hornet Strike], (Primed) [Pistol Gambit], (Primed) [Target Cracker] and normal or Amalgam version of Barrel Diffuser.
(Amalgam Barrel Diffuser is recommended over the normal Barrel Diffuser simply because the dodge speed synergizes well with Rolling Guard)

[Primed Heated Charge] adds +165% heat damage, this mod is used on all builds simply because it is the only primed elemental damage mod, and heat stacks are really good.
If you are planning to mostly use the secondary fire mode, then i recommend that you swap out Primed Heated Charge for Magnum Force instead.

The first, most popular build is the "Viral" build.

Viral is the best status effect in the game, a viral stack applied on an enemy amplifies damage to the health of the target, increasing damage it takes by 100% for 6 seconds, additional stacks adds 25%, up to a maximum of 325% (10 stacks).

[Frostbite] and [Pistol Pestilence] are recommended for creating Viral, both adding 60% elemental damage and 60% status chance each.
Consider using Ice Storm instead of Frostbite if you are using either Arcane Pistoleer and/or Energized Munitions.
[Ice Storm] increases cold damage by 40% and magazine size by 40% (form 8 bullets to 11)
The additional 3 bullets, combined with Arcane Pistoleer and/or Energized Munitions, will allow you to use secondary fire more without reloading, and deal more damage. (because you have more bullets)
[Deep Freeze] and [Pathogen Rounds] are your only other options for creating Viral, both adding 90% elemental damage each, instead of 60%, and neither increases status chance.

The seconds popular build is "Corrosive".

Corrosive reduces targets armor by 26% for 8 seconds, additional stacks adds 6%, up to a maximum of 80% armor reduction (at 10 stacks)

[Jolt] and [Pistol Pestilence] are recommended for creating Corrosive, both adding 60% elemental damage and 60% status chance each.
[Convulsion] and [Pathogen Rounds] are your only other options for creating Corrosive, both adding 90% elemental damage each, instead of 60%, and neither increases status chance.

Corrosive is better than Viral in very, very few cases... barely any cases to be honest.

However, using corrosive with combination of a [Tenora] Prime Viral Build and using the Warframe Mod Vigorous Swap is not a bad idea.

But even then, viral is more reliable.

The Third Non-Popular Build is Pure Heat.

Heat stuns (makes the enemy panic) the target for 1 second, and after the first second it deals damage (based on your weapons heat damage) for 6 seconds, and reduces armor by 15% every 0.5 seconds, up to 50% armor reduction.
Additional Heat Stacks do not increase the damage, but refreshes the damage and armor reduction duration, and stuns them again.

This build is only recommended if you plan on using a different weapon for applying Viral stacks, like Tenora Prime.
Use (Primed) Heated Charge and Scorch for heat damage.

You will have either 1 or 2 mod slots open, recommended mods are:

{[Lethal Torrent]}, this mod adds 60% multishot and 60% fire rate, and is one of the best (and most popular) mods simply because it increases multishot.

{Magnum Force}, this mod increases damage by 165% but reduces accuracy by -55%, the accuracy reduction does not matter much if you are only using secondary fire mode.
(since usually you are really close to the target when going for secondary fire mode)

{[Sharpened Bullets]}, this mod, when killing an enemy, increases critical damage by 75% for 9 seconds while aiming.
More critical damage is nice.

{[Hydraulic Crosshairs]}, this mod, on headshot, increases critical chance by 135% for 9 seconds while aiming.
135% critical chance is really good, but landing headshots with secondary fire mode can be annoying. (because of it's recoil)

{[Primed Slip Magazine]}, this mod increases magazine size by 55%. (From 8 bullets to 12)
As previously mentioned with Ice Storm, the additional 4 bullets, combined with Arcane Pistoleer and/or Energized Munitions, will allow you to use secondary fire more without reloading, and deal more damage. (because you have more bullets)

{[Anemic Agility]} {[Pressurized Magazine]}, this mod (after reloading) increases fire rate by 90% for 9 seconds while aiming.
This works really well when going for secondary fire mode build.

Exilus Mods

Recommendations (in no particular order):

{(Primed) [Pistol Ammo Mutation]}, this mod converts unused ammo pickups into pistol ammo.
This is always decent.

{[Reflex Draw]}, this mod increases holster speed (weapon swap speed) by 200%, it can be very useful.
However, [Reflex Draw] is quite useless if you are using Vigorous Swap, since that mod already increases holster speed.

{Eject Magazine} is... "cute", reloading the magazine by 20%/second while holstered (fully reloading the gun in 5 seconds)
This mod is not super useful since Pandero's reload time is only 1 second, but it is still decent.

Riven:

Don't, currently they are not better than regular mods, unless you have a god-tier riven.

And if you have a god-tier riven, id suggest selling it for a boatload of platinum instead of using it.

[Pandero Prime] is decent on steel path, but still a fun and somewhat elegant gun to use.
