Buying weapons is not as important as sustaining your life. If you have money purchase the healing potion. More heal = more life = longer in the dungeon = farther you'll progress. The items will come to you from opening chests.
Getting hard badge with a Mage.
1. Get a mage character (example Atlantean Magnus)
2. +1 life, +2 will, and +1 intellect per level (or alternate +1 life, +1 will, +2 intellect )
3. Get bolt from weapon (bolt is good killing most monsters, except lightening balls), bolt is also instantaneous.
Secondary attack flame bolt, fireblast, etc.
4. Lure monsters out 1 at a time, in the later stages you can lure more if you are confident you have enough mana to dish out the pain.
5. Items looks for +will, +intellect, +life (listed based in order of priority)
6. Skeleton casting is great for decoy when you want to run away. While running away, summon him and hope that the enemies concentrate on him.
7. Other useful skills. Entangle and Sanctify. (I rarely used these)
The key to surviving is luring out the enemies in small groups.

I killed Clive by luring him into the left most corner. His rays could not touch me and I was in range to deal damage.
