This game has seriously messed up RNG

[Felis]

Edit: IMO crafting and gathering should have yes the initial success rating but scale based alot like how desunthesis works. Lets be real you crated a million of these damn leather wristbands, how often are you really going to fail at it at this point? its like rolling a d 20 for something a person can do in their sleep. "im sorry sir, you failed to turn the knob on the door, you die instantly"

It depend on if you upgraded your equipment or still use the equip of an apprentice. High experience in crafting something can't do much if the equip is shit.
If you can't get it near 100% then the equip is not good enough (or you messed up your skills)

Your example with rolling a d20 to open a door will be 100% with a nomal hand (good equip), 75% with a broken hand and 25% if the whole arm is broken. And 0% if you are armless
