A few tips:

1. Use more strength til you hit 15. Then, you will be powerful enough to use more INT.

2. Stay in the low levels. This will allow you to adapt to the game and use less pots.

3. Find groups. You won't last in the beginning without them. I never have a hard time joining a game without people already there (or soon follow.)

4. Be patient. The economy is far from PL. Drop liquidation is a little on the ridiculous side. Once you get use to hoarding, you will do better.

5. Stay away from cs. Prices are also ridiculous and are controlled by plat spenders who have bought a ton of gold with plat. Drops are common and useful, so refer back to point 4.

Good luck.
