Pissed I needed to stop using my wolven gear set, as it basically has become pointless in term's of defense stats. Lvl 34 gear just doesn't cut it for me at the moment, I had to revert to my level 39 oath breaker robe's.
Level 41 Undvik set is already OP against humans, combined with griffin decoction and the skill for 25% protection from oil used and you get resistance close to 100% and taking 10-20 damage from red skull enemies.
I once tried Undvik set with combination I mentioned above against 20-30 level 54 guards. Maxed out Quen and Yrden and I just stood in one spot, casting Quen for shield and alternate Yrden and didn't even attack.
