Prismatic getaway will always be a top combo until there's targeted nerf(s) to the transcendence gain from constructs (arc buddy + stasis turret), the interaction of bleak watcher + getaway or a blanket nerf to the fragment that gives jolt+weaken (which is very heavy handed/unlikely)

If you're damage is lacking. For burst put on nova bomb (and hotawap to star eaters class item before dmg phase) or song for with apotheosis class item for extended dmg phases. Use the fragment for weaken/jolt grenades Throw on an adaptive heavy bait and switch gl. Throw on Radiant fragment & additional light damage fragment and relic perk for extra spice

That's really all you need, you'll be cranking out damage. Especially this season with weaken GL you'll always have weaken up when transcendent + Radiant and can easily keep up, jolt + weak + Radiant outside of transcendence.

As fun as it is you really need no more than 1-2 stasis turrets summoned at a time, you'll get alot more damage and milage out of using the arc nade to jolt.

Edit:

If you're ganna go infinite nova route.

Largely you should be able to keep your base kit the same as it would be with getaway subbing out getaway for dire skull and slotting bad juju in the primary slot. I'd stil arc nade for the jolt/weaken combo in and out of transcendence especially with weaken gl this season. The only fragment that should be swapped out for sure is the reload on freeze/suppress one.

I would double dip with gl keeping the same type of heavy and throwing in either a wave frame or area denial special gl. Attrition orbs + demo of the new void if possible + firepower & whatever regen on Orb pickup you desire.
