PoE Static Strike, Fire builds

I've been trying to cook and pretty much have concluded that using Prismatic Burst as a main skill will end up underwhelming (without Shako at least). (Rolling Magma has similar base damage and same damage effectiveness so should pretty accurately reflect PB DPS) Here's my non-budget lvl 100 take using mine auras to get almost 7x damage as well as Annihilating Light. I've gotten enough CDR so PB has a 2.52 hit rate which matches perfectly with lvl 1 Static Strike's 2.5 beam hit rate. This ends up with a build that has a clunky play

PoB: T16: So I made a Molten Strike Assassin with about 1-2 div investment that relies on Mantra of Flames buff stacks (which have to be edited into PoB) and specifically fortify (which gives 100 buffs regardless of cap), multiplied by Replica Last Resort. Damage is ok (1.4m melee dps and 1m per ball with 6 balls that are slowed to hit a single target well). At lvl 91 it can do T16s comfortably (with essesnces/strongboxes and harbingers on my tree not causing too much of an issue) and Maven Atlas Invitations, I haven't tested it on
