Far too many attempts but I got it.
Solar Warlock w Sunbracers ALH+CC Riptide, S4A+Incandescent Epochal Integration, Xenophage for everything till the final boss. Then I swapped Xenophage for Recon+B&S Apex Predator, and brought Sunshot.
On to the next one!
Well done. With Solo Operative available till June this is the time to do it!
It really does help. I’m gonna miss it bad once it’s gone lol
