There is an assumption that this torso (Ligtning Platinum Vest) does not have a declared resist, since it is almost always the first blow to my resist 117 that turns out to be 350-360 damages. At the same time, I almost never hit damage = 300+. even in negative resist!
After the ddos attack, when I was able to enter the game, I was happy to see the damage that was really in the resist! Damage was 190-250 damage. But the next day everything returned to ignore the resist on this torso.
video as an example
I was once struck by a “night eagle” for 350 damage. Yes, in resist 117 - the first move of the enemy. Sorry I did not save that fight.
