vAS, particularly if you're doing the harder modes, is single fight that can last very long and is very death-prone. It's not uncommon to see a group that's new to that trial take an hour and have something like 20 deaths per person.Why are you in a situation where you're fighting with broken armour?
I noticed this in VMA recently I would get to round 7-8 with 1 death lag death and my armor would break during the boss fight and I can't shield because my armor broken.
