Great!

In the first place, start cleaning the monastery.
You'll encounter 2 boss-like monsters there, so save up all your potions and spell scrolls for those ocasions.
Make sure you explored it VERY well.
-If you can, use the SEARCH function if you think an item could be arround.
-Camp while having your back to a wall.
- Make sure you are confortable with your party. If not, restart the game with another one. You need at least one wizard/magic user, a priest, a good fighter, and a thieving chracter. Concentrate on one or two stats: the faster you get 100 as your primary stat, the better it is.

That's all tips for now.
