Don't apply agony resist to your rings
That’s sort of expected. Your legacy +5 AR will be replaced by the new AR infusion so we really need to combine new AR to more than +5 to make sense inserting them. Anyway, thanks for confirming this in game.
I think he means adding the 5 agony/5 power type upgrades is causing the native +5 agony granted to pre-existing infused rings to return to a +1?
