PoE SnooBunnies5527 builds

Hi I play a raider white wind Reave build and I’ve recently added the new heat shiver to the build and now want to add the admiral cause it seems like a funky and cool mechanic that can dish out a bunch of damage. Problem is POB doesn’t quite calculate the admiral I think and since I deal cold/fire dmg, I want to reduce enemy light res. 1. Any other sources of -light res besides raider exposure and curses? 2. Is my assessment of how the admiral works correct or is there something im missing? 3. Any other tips or stuff I should know or test? Build for referenc
