Soloing as a level 13 untwinked Ogre Shaman

[Lhancelot]

For simplicity sake, I always do Oasis at lvl 13.

You can pull solo caimans on the beach to the waters edge away from wandering mobs and solo quite easily here.

The down side is there is no loot to speak of, but the occasional rune or words with croc meat.

When you need to afk, you can run up to one of the large rock pillars and sit/med safely on them.

Another plus is sometimes high levels come and buff lowbies as they pass through.

Oasis will take you to 20 easily, and some people stay till 24.
