Another act 8 node bug (8.1.4 aspect of war)
Parry vulnerability gives you a fury when you parry (+75% attack) and whule they are stunned from parry +200% attack. However hitting them while stunned from parry and without stun gives the same damage.
Additionally cosmic ghost rider doesn't get a fury from his sp3 as the fury from parry vulnerability counts as a judgement. This isn't a bug I think but a node interaction to keep in mind.
