If are at the tutorial, and you would like to increase your skills, then make sure you loot every single weapon/armor/shields and potions and repair hammers.

If you would want to increase your skills, then pick the the thief birthsign and help barus and glenroy help fight off the assassins until your skills are at least a master or expert.

Now if want to keep both glenroys and renualts katanas, then drop renualts katana and glenroys will then appear and you will offically have two of them.

Don't forget to do the duplication glitch for the hammers/potions.

Keep the diffculty at easy-normal, but do not do it super hard!
