Hey guys, i do mostly arena runs and choose my pets largely on bonus damage. There are several that give 10% more damage and grimm and slagg give 12%. I noticed malison reduces armor by 10%. I'm not really sure how armor works and am wondering if reducing the bosses armor by 10% would be the same as increasing ur own damage by 10%? Does anyone know? I know that whole group takes advantage of the armor reduction but let's just say I'm soloing it (which i don't, i'm just wondering if armor reduction is the same as increased damage).

Also, Grimm grants BOTH 12% damage and 10% armor reduction. So he should be OP right? I had been rotating between slagg and malison but I'm thinking I should be using grimm more.
