Does anyone know a good guide for that...I know I'm late to the party...just want to get started leveling pets I might need for that. Thanks

Thanks so much..I used the stones on the ones you suggested. I do have a lvl23 Unborn Valkyr rare that I can get to 25. Now comes the fun part of learning how to use them.

I only have a handful of lvl 25 pets but I have 11 of those garr. quest stones to get a lvl 25 pet. I'm trying to get some idea's on some must have battle pets to use them on. Thanks for any help/advice.
