Yeeeeees, optional boss down. Fuck him x)
I think I have a pretty good strategy.
First phase, not much to say. It's pretty straightforward, the cleave are the biggest issue b
- Don't try to do something funny on the very 1st attack, just get close to the boss and let him do his aoe
- Try to stay in his back, 2/3 hits then back off
- You can hit him when his charging some kind of buff, even if you get hit by something, it's worth it
Second phase:
- Don't lock this fucking camera. Seriously, just don't. You may think it's a bit hard to hit the boss without locking him but it'll save your life and your sanity
- Bring him either close to the fog wall or to the big statue. That way, if he decide to charge you can safely evade by going to the opposite side
- Turn clockwise around him when he spits fire, then hit him 3/4 times, then evade (don't evade to find yourself between him and a wall, if he charges you're dead)
- He has 2 "physical" attacks where he extends his arm, this is your chance to place at least 2 hits
It way sound obvious but with that in mind I finished the fight with 12 blood vial. I almost never got hit in P2. Also, equip the Impurity rune to be able to summon a NPC. He's not very useful but at least he can distract the boss for a couple of minute x)
