Kripp's Fiber Optics Pulse Rifle Dooley Build
Kripparrian
Dooley
Overview
If you're building a comp that wants to ramp up a Core ASAP, adding 
Fiber Optics can greatly accelerate your burst.
In this particular Dooley run, Kripp pairs Fiber Optics with a 3x Multicasting 
Pulse Rifle, allowing it to Charge the 
Ignition Core 6x times on its own
Our guide will cover this build's core synergies along with supporting items/skills, but be sure to watch Kripp's video guide to see all his decisions.

Ignition Core
As the Closed Beta has developed, the Ignition Core has proven to be a versatile option that can be built outside of pure Burn builds - in fact, this particular build had it as its only Burn item!
By Charging it with a ton of items to the left of it and ramping up its Burn damage (through sources like the Fiery Enchant or Second Degree Burns skill), it can deal a ton of damage on its own by rapidly casting.

Fiery Ignition Core
Pulse Rifle + Fiber Optics
One of this build's best synergies for ramping up the Ignition Core is the combination of Pulse Rifle and Fiber Optics.
Pulse Rifle, especially at Silver-rarity and above since it casts at a base 3.0 seconds, is a fast-casting 3x Multicaster.
By placing it to the leftmost position and having a Fiber Optics on board, it essentially turns the 3x Multicast into a 6x.
What's nice about Fiber Optics is that it can be anywhere on your board, so it gives you flexibility in positioning the rest of your items.
Note that the Pulse Rifle and Fiber Optics were respectively Enchanted with Deadly and Shielded, neither are necessary.

Supportive Items and Skills
Cool LEDS + Heavy Atomic Clock
The remaining items in the build helped to further ramp up the Charging of the Ignition Core while also providing defense.
- Cool LEDs = Disrupts enemies with Slows and scales alongside Ignition Core casts
- Heavy Atomic Clock = Incredibly fast casts at 1.0s to disrupt the enemy with Slows (make sure to look for Gunpowder)
- Uzi = A 3rd source of Slowing your enemy + instantly Shields when Cool LEDs and Core cast
- Copper Ed = Mostly acts as the one friend to activate Pulse Rifle's Multicast but also provides some Shield + Poison

Supportive Skills
This versatile build can benefit from basically any Skill besides Healing, but you can get a TON of value from ones that grant benefits with each time the Core casts.
Here are some examples that Kripparrian chose or found as PvE drops.
Coolant leak (crowd control that procs off Core use)
Fiery Rebirth (rare hit dropped from the Radiant Corsair PvE Encounter)
Heavy Machinery (Haste burst that procs with every Core use)
Titanium Casing (Shield scaling that procs with every Core use)
