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!
That’s awesome, congrats!! I’m glad to have given you the push!
