There are Lions, Spiders, and Bears all of which give good exp, but poor loot
To get there, go to the Docks in South Qeynos, get Dofus kamas on the boat, and exit at the first stop. This small island spawns many wisps, and is great exp from levels eleven on up to thirteen or fourteen. Also, wisps sometimes drop Greater Light stones, which can be taken to the Gypsy Mrysila in North Karana.
West Karana is a good leveling spot if you have a Ranger to track things for you. There are Lions, Spiders, and Bears (oh my!) all of which give good exp, but poor loot.
Eastern Antonia Area - On the East Coast of Antonia, your adolescent years will be spent with the Orcs in the East Comma lands. Both camps are usually crowded, so it is best to locate a group.
Centurions and Legionnaires will fuel you to level thirteen or fourteen, at which point you will want to move to the Derv camps in West Common lands or Northern Ro. Also, the Derv camps in both West Common lands and North Ro are great up to sixteen or seventeen.
Another great place for people between twelve and twenty is the Oasis of Marr. Here you will fight Caimans and Crocs up to level fourteen and fifteen. Then you will hunt stronger Deepwater Caimen and Deepwater Crocs in later levels.
Also, Misty Thicket will still be giving you exp up to twelve or thirteen with Giant Spiders and Scarabs.
