Formulae for damage dealt to the player

Sorry if I'm posting this in the wrong section, but I couldn't find anywhere better for it.

Does anyone know what the formula(e) are for damage dealt to the player from a mob? I expect it's a variation on the standard ones:
MAX = (Primary Stat + Secondary Stat) * Weapon Attack / 100
MIN = (Primary Stat * 0.9 * Skill Mastery + Secondary Stat) * Weapon Attack / 100
but I have no idea what a mob's primary and secondary stat would be, nor what their mastery would be. I also have no real indication that these would be the formulae, other than the fact that I can't find any other formulae for damage dealt.

I do know that there is an entirely separate formula for damage reduction from a mob's attack compared to how mobs reduce damage from a player, which is:
Original damage - ((Your total weapon or magic defense)/3)
so this suggests to me that there may be an entirely separate couple of formulae for the min and max damage a monster can deal to you.

The question was asked back in 2017 in https://forum.maplelegends.com/index.php?threads/mob-touch-magic-damage-formula.15293/ but no answer was ever given. I've scoured the internet but I can't find anything either. I was close to downloading the server files for a generic v.62 server and looking for clues there, but I figured I'd be better off asking the community first.
