like, here's an exercise:
make a little program that just prints out d&d "stat arrays" in various orders
if you have any significant experience with the system you can immediately say "that's fine for a [class]" or "you will hate the game and yourself if you do this"
explaining why is a lot of work, but the net result is just… knowing you should always do it like *this* and not like *that*
think about the metric ton of "why can't my shadowheart hit anything?" posts about bg3
