Except it can't probably due to coding. . You need to test amp dmg vs synovia. Bet they wont work either. Just accept DE said it wont work, and stop trying to force things when it's already been stated. And changing the game for void dmg, which is "neutral" vs using anyone who could proc towards rad would be just silly. If this be the case, you would be asking the dev's to fix what may be old coding for a bad setup, if you can get get xaku, surely you can get a rad buff from someone or do hellminth.
