The levels provided here are solo levels, so you will need to adjust accordingly if you bring a duo or trio down to these camps. The level ranges are a little conservative to cater for melees. Adventurous mages that nuke an enemy to death can try out some of these camps one level below the recommended level range.
While soloing off Beastmaster pets can be a very nice alternative to party seeking, remember that you will usually only have yourself to rely on. Bring some form of reraise, sneak, invisible, and a way to get home.
Sometimes, a BST mob may not actually be at the camp location, in which case you will have to find a way to kill the existing mobs until the BST spawns. Such camps are marked in blue.
Finally, be aware that other higher level players may very well accidentally (or intentionally) come by and kill your Beastmaster.

Some points to note:
* When a BST spawns a new pet, the pet will be treated as behind the mob. That is to say, you can immediately pull the newly summoned pet immediately, with no fear of the Beastmaster linking.
* Pets do not aggro- only the Beastmaster will.
* Special thanks go to Salacia for his original work.
