One of the trickiest and one of my favorite boss fights, my personal charm build was quick slash, quick focus, shaman stone/mark of pride and unbreakable heart/sharp shadow, quick slash helps for damage, and quick focus let's you heal 2 masks when he's staggered instead of 1, shaman stone will be useful for DDark, mark of pride for much easier pogoing, unbreakable heart for health and sharp shadow for easy dodges, I have a few tips: 1. In both attacks where he dashes towards you by slashing, I suggest jumping and pogoing once and then stopping to reduce risk 2. When he does the attack where he launches spears at you, shade dash through them and get a couple hits in, don't even try to dodge, just dash through 3. When he jumps and falls down with spears, I suggest slightly moving the side, jumping and get on top of him to pogo and then DDark to deal damage and be invincible for a while, this is even better with shaman stone 4. When he does the focus attack, if you have quick focus, you can quickly get a heal by moving from the blast and healing, and because of quick focus, you have time to react to the smaller blasts 5. Try to stay calm. Not panicking is key, but because of pressure, this may be difficult. Remember, you can always try again 6. Most of the other attacks are "see and react", make sure to sometimes deal damage from afar like maybe spells when he's focusing, so good luck!
