All resistances on one of my characters is -97.3%
I have tried to reset all skills and paragons, remove all gear, restart game and still same problem…
If you are in Torment 4, possible, since it reduces resistances and armor a lot.
Hover over your resistances in stats, it should tell you how much you really have and can use.
Thanks for the reply, you seam to be correct I did not know that it was so big of a jump.
