Temporarily stickying this here to help out anyone heading to the new public dungeon, Strayana's Spirit Cave. The map looks pretty rough, but it's complete. Note that "north" on the map is actually in the direction of the bottom right corner, not the top border like normal.

The monsters and some of their drops are listed below. No Small Healing Potions!

Edit: Concerning the rumor about having to kill your own class for good drops, it's not quite true. What is true is that to get good drops for a certain class you have to hunt that class.

The simple version:

Titan drops all Titan equipment and all gloves.
Knight drops all Knight equipment and all boots.
Healer drops all Healer equipment and all helms.
Mage drops all Mage equipment and all pants.
Rogue drops all Rogue equipment and all shirts.
Sorcerer drops all Sorcerer equipment and all weapons.
