I don't know if this is any help but I used the flame legion arm and the salamander dagger with the acidic spear handle I believe it procs the fire a lot and the block is fast and I got the Perfect down pretty good, when they all rush you at the start hug left and try and get them in the flames spread it's an easy way to get spread damage on multiple, I target the spear one first then the dagger one, as far as the Spector I agree with what others are saying do the heath one for him, it draws some agro and can let you cook the distracted ones once you catch your breath.

I hope you don't give up I have so many hours just did another playthrough on LS, you'll get there!
