From my understanding Angon can't be resisted and gets you 25% defense down with merits and gear. Doing better than 25% but requiring accuracy checks are Corrosive Ooze from BST and Tourbillion from BLU at
My question is directed towards landing Defense Down on resistant mobs. Are all defense down effects Wind based, and thus don't land on wind and ice mobs more readily? Or does the source matter?
Example Corrosive Ooze, Venom Shower, and Tenebral Crush can be bursted and are not Wind aligned for their damage.
