The Blur passive skill states that it reduces damage taken by 17%.
Another answer stated that different classes of damage buffs stack multiplicatively, so I would suspect that also applies to damage reduction buffs. However, my character sheet shows this:
I do not, in fact, have complete immunity to poison damage like those numbers would imply.
How much damage reduction do I really have with Blur? And does the difficulty level negatively affect my resistances or just the amount of damage monsters do?
