1. Always keep at least 2 rez and escape scrolls in
inventory.

2. When you see a good buy on SS or SP stockup!! You can
always keep them in wharehouse. This could also be a
moneymaker for you too, if you buy low and take a bunch
with you to a hunting area where people are always
running out and sell them for higher than you bought
them.

3. Make sure if you are a fighter of any type to invest in
good jewlery. This increases your MP.

4. Always help Newbies out. You never know how powerful an
ally that they might become.

Just a few tips to get started I will add as I am loafing at work .
