Ok metal slime is a character, up north on a mountain. The desert, look where you need to go, it is confusing, Ive found a town, a base, a bandit cave, just walk all the way right....all the way up.....all the way down to find every thing. You might have an old DL, as I could go in the orphanage. The monster I was level 7 to 10 with my characters. Most give ok exp and gold, plus some items. Nothing to special. To make things easier, walk all over the world map. There is hidden treasure that makes life easier all over. The heal bot is north of the desert.
