Cave-ilvania

This monster packs a punch. 

Once you have leveled up to your satisfaction you can start taking on the rest of the Earth cave. There are a lot of strong monsters in the cave as well as quite a bit of nice treasure. One thing you need to watch out for is the earth elementals that you can run into whenever you step in front of a treasure chest. A hit from an Earth Elemental can take a big chunk out of your hp so be careful and get heal up before you open a treasure chest.

This so called boss is about as easy as a lot of the random monsters

The layout of the Earth cave is kind of confusing so be sure that you are strong enough before trying to take on the cave. To get to the second level you need to take the eastern route when you start on the first level. On the second level the stairs to the third level is on eastern part of the cave. Other than the Elementals there are plenty of monsters that can poison you as well as cockatrices which can turn you into stone.

Be sure to take this before you leave

On the third level you can find the vampire, It looks sort of like the rest of the bats but stands still in the middle of a room. Talk to it and it will transform into the vampire and fight you. The vampire isn't that strong as in my experience the vampire crumbled in the face of one barrage of a hasted warrior's sword blows. In the back of the room you can find a star ruby if you walk out the other door you see a plate on the floor which is emanating evil, enough though you can do nothing about it at the moment.
