Unless negate stuns the blades then I don't see how it would help me. My problem is that I can't seem to attack the boss much as I'm forced to keep reapplying ward and heal every couple of seconds as those traps are hitting me constantly. I don't have much physical resistance as I'm more protected against fire as a vamp sorc.Use negate b4 boss goes into crybaby mode, you should not be running out of resources in VMA unless you are a pure dps build. If you are a pure dps build the bosses will drop quickly. Maybe for this fight use max health regen food and use harness as main shield for resources back? Heavy attack resto obviously if you are using that.
Edit: This is the worst stage in the arena when you start farming, ice stage and poison as well....also the second last boss on igneous plains who rips you if you do not have heals (you will be fine on that one compared to stam).
