Extra gold:
Use the following trick to get a lot of gold when you do not have any inventory remaining. Be an alchemist and level up the spell Transmute so that everything around you turns into gold. Note: This spell must be at a high level to be worth it. 

Defeating Bosses:
When fighting a boss that can overpower a Druid in hand-to-hand combat, summon a "pet" and equip a strong bow. Because you spill a lot of points in dexterity, the bow should be very strong. You can easily pick off Bosses that way.
