I'm having trouble with them as well. Does anyone know how much HP/MP the Soulblazer's have?
Also, when I use Rasp on Wrexsoul, it says "Wrexsoul lost focus" then "Wrexsoul came to his senses" immediately after. What does that mean?
I was watching a video, and is the drop the same if you kill Wrexsoul or just the Soulblazers?
