Right now I'm stuck on the Final Battle with the forbidden one, so I went back and started grabbing all the upgrades before facing him again (last time was no magic and half life, went straight through since fighting Satan)
Also perfecting Just Guard works wonders on the harder monsters making them much easier than my 110% run (no DLC) on the 360 version
If you guys want I can post some screens (1080p or 4k, and even downscale)
