This build is amazing as is, but Gunpowder Gamble has a secret interaction that makes it next level. Throwing Gunpowder Gamble as soon as it comes up doesn't trigger the cooldown timer, and Gunpowder Gamble being an ability means each kill it gets gives 4 charges towards the next one.

Class item -> Spirit of Inmost Light + Spirit of Synthoceps

You loop Gunpowder Gamble with a buffed (Synthoceps) Threaded Spike and Jolt grenade that's refunded through your kills because of Devour from Buried Bloodline.

-Grenade -> Cure on kill -> Mending

-Gunpowder Gamble -> increased size and damage (Facet of Ruin)

-Orbs -> Restoration + Radiant

-Any kill -> Void Overshield (Void Hegemony)

-All abilities -> Inmost Light -> constant boosted ability regen

Ability choice is balanced between darkness and light, giving you easy Transcendence access.

Gunpowder Gamble works on a charge system.

• Solar weapon kills give 1 charge
• Elemental debuff kills give 3 charges
• Ability kills give 4 charges
• Super kills give 6 charges

Both your abilities apply elemental debuffs to targets they damage (Jolt and Sever) which not only makes kills progress Gunpowder Gamble, it also activates stylish executioner.

TLDR throwing it immediately lets it chain itself and clear rooms alone.

Heavy and primary weapons are personal preference, but try to use at least 1 Strand weapon to take advantage of Threaded Blast on the tangles your threaded spike creates.

A final note about Transcendence; getting a Gunpowder Gamble charge during transcendence holds until the meter is expired, locking you out from center of your build. For this build Transcendence is more a panic button for extra damage resist or ability refills if you're out of everything, not something you use whenever its up.
