At the tutorial, before you do this you will need a lot of patience (trust me in the end, you will not regret it).

Make sure you have all the weapons, armor, potions, shield, arrows and hammers.

Now when you get to the part where Glenroy says it a trap and Barus tells you to protect the emperor, do not do that.

Instead, help out Glenroy and Barus, fight the assassins. If you want both katanas, drop Renulats and then pick up, Glenroy's katana and you will have both.

As soon as Glenroy dies stay to the left side, right where the gate is and attract the attention the two assassins, buy using the fireball spell once or twice and they will focus on you more than Barus, allowing you to increase, your skills up more faster (don't forget to do the duplication glitch for the potions, hammers, shields, armor, weapons and arrows).

Do this until you are at the rank of journeyman, expert or master.
