enemies health set to 0 crash/freezes your game in most rpgmaker games, just spawn yourself scrolls of enlightenment which allows you upon used to save your game with it you can easily save scum, give yourself miasma sword, Miro said he reworked the sword in 1.4.0 but I haven't touched 1.4.0 yet before that, miasma sword was one of the best weapons in-game apparently miro said you can kill things which you wouldn't like that ghost knight, using gauntlets or legs protections prevents enemies from cutting your arms/legs but you can simply use set entire party health at max this should cure your lost limbs.
I'm a known cheat so I know most.
And cure all party cheat does
not regenerate limbs. There is this cure all ailments (forgot the exact name) cheat, but it only removes things like poison/bleeding(normal).
Things like limbs or ass bleeding somewhere in different sections (switches or variables menu).
In some games you can regenerate fallen enemies or enemy's body parts. Or have them "set to 1 HP" when they are all bloody.
As for armour, true. But I also use this heavy Helmet (forgot the name) which prevented/decreased chances of instant decapitation.
They say Miasma is best sword, but if you increase stats, then I prefer using 1h cursed something with a SHIELD.
But the most fun is when you cheat god affinities and soul stones (now you can buy skills). Getting scrolls (items) to learn skills is ok as well.
Ghost can be defeated by items or spells (explosion vial or something). I remember doing this.
NOCLIP still rules. You can escape enemies into walls.
