I know this kind of thing has been done before but I wanted to do one myself. This fixes the mismatched blood for the Spectre, Hell Knight, Baron of Hell, Cacodemon and Lost Soul.
- Spectre will now bleed the same fuzz style you that you have set for renderstyle OptFuzzy (particles disabled so that it won't look bad with non-fuzz settings).
- Hell Knight and Baron of Hell bleeds green like their death frames.
- Cacodemon bleeds blue like their death frames.
- Lost Soul has no blood at all or no blood decals. It never made sense to me for a Lost Soul to bleed since they are pretty much just a flaming skull with no flesh.
- Revenants have darker blood to resemble it starting to dry and such.
- Lost Soul health reduced by half to be closer to Doom 64 and PSX Doom
