Overview
Insanely fast xp exploit for all weapons, agility, strength, vitality, mainlevel, and warfare.
Unarmed
(Video guide, first showing unarmed then showing the rest of the weapons)
You will need to find anyone, just anyone.
Then you need to drag their corpse ontop of an item that will allow you to hit them with your fists.
Alternatively the method I used was in Sasau I knocked out a gravedigger, then I dragged his corpse far out into the river as I could possibly put him. He will float up, after that you can just wail on him.
This will be leveling up Unarmed, Warfare, Vitality, Agility, and Strength.
Every weapon
Find a person who is tagged as essential. (Can’t be killed)
Stab him until he falls over.
Keep stabbing/hitting his body.
This will raise any weapon that you use as well as agility, strength, vitality, mainlevel, and warfare.
Notes
You can do this without raising the guards attention. However with that said it is very hard to do. Do it in a city you do not care about, and pick up the infamous perk that allows you to raise your reputation faster and will lessen your time in jail.
