Lvl 16 Pally Where is a good place to solo?

[Sepulveda]

You might try hunting the mummies that wander around in South Ro. The crypt mummies should be totally doable at 16, and even the sand mummies should probably be possible. These stay blue until at least 19. There are also ghouls and dry bones skeletons that wander around. The DBS are pretty difficult, but you should be able to do them by 18. You can sit in the little cracks in the wall just to the left as you come in from oasis to rest safely. The loot is pretty meh, but you can get raw hide armor from the ghouls, and 2-3g per kill sometimes from the mummies.
