-----------FIXED------------
Hi there, seems i found a little bug/exploit - whatever.
i was in the Shrine of Seven Stars for surching some pets to kill with my twink (76) -
befor i joined them i saw a Quest from Sara Finkleswitch named "What We've Been Training For"
i turned in and joined the fights against pets around the shrine.
(with lv 76 23k xp without resting/+xp etc - nice lv spots while waiting for dungeons :P)
well - after some battles i recived a archivement named "Legendary Pet Battler" (win 250 battles)
and see there .. i can take the quest a second time.
dunno if its a bug - but u can exploit it rly easy for gold, twink xp, pet bags.
seems u just need to get a archivement for re-doing it.
btw dun look at the XP i get there - its only 33k.
just gettin 99k for havin a lv 47 twink on my side with "Recruit a Friend".
(sorry for my bad english - but i hope ull understand it)
Edit: runned around to test somethin.
was duelling a twink - got the archivement for win
she gave me again the quest - but i just see it twice in my quest window
so it seems to be rly buggy and can be exploidet if u can join a fight with 3 25 pets and win it 10 times.
it seems its a rly new quest (5.3) and the bag isnt listed anywhere atm.
most ppl are sayin they got +50% xp a hour for pets - and some stones to make pets to rare ..
well - enjoi.
