Hello.
I have a companion 'Demon Warlord' which is supposed to give me a bonus to damage with spells. It indeed gives me a buf called 'Corrupting Essence' which - according to its tooltip -gives '+1% Magic Damage Modifier'
However I see no change in my damage stats or spell tootips regardless on if it is active or not. Also 'incarnate dot debuff' does exactly the same amount of damage (I'm not 100% about Fires of Gehenna as they may vary so it would need lot of statistical data to notice 1% damage bonus)
So my simple question is - does this buff work at all?
