i need help making a character customisation without scriots please
Without 'scriots' you'd have to be using a ton of different charsets to accomplish customization.
I'm sure someone here can tell you how to do that, but it's going to be a ton of work that can just as easily be done with scripts.
It depends on what you want to customize? Appearance, stats, class, etc...
The simplest way are conditional branches, but if you want it to look nice you'd have to use picture eventing; you'd be better off with a script.
