2 fragments left for ToM and I couldn't wait for an easier CoO tier 3 boss. So I watched videos on Youtube how to kill him solo in under 2 minutes. Took me about 8 tries. Just to let you know, I view myself as an average player. Nearly everyone should be able to do it without much hassle. It's not that hard. You just need to meet a few requirements like having a Raze-Lighter (not sure if possible with the other exotic swords).
