Burst Damage/Poison Damage

My toon is taking way too much burst and poison damage. I was rolling thru a tier 75 NMD and the boss is the one who vomits poison. He instantly wiped me twice with his attack. I’m 100 with 10k armor and 70% poison resist with 25k life. Also a friend on pc helped me with my tormented Grigoire and he died 5-6 times and messaged me after asking why he was dying so easy and stated he didn’t have that issue in his instance. Account related or maybe console related?
