oh jester is fun, if you are not on the combo side build you can see how fast u lvled fighting against mob with 10+lvl above you when u are only lvl20+. But yeah its damn expensive for the throwing build, whre else for the combo build its quite cheap and it have lesser combo due to not having combo 2 skill.
The bahamut/phoenix pet thing is kinda hard or should i say very hard to get, the chance of getting it was about few %? And i dont remeber anyone having one when im in Jso...for the onrpgers n STL, but it seems preety common lately in jso tho..
