This took me 191 kills to achieve. But well worth the time, nice pet!
I got this fool.
This is my go-to pet for elementals. Hands down.
Got this one after a number of kills, don't know exactly how much, but I think about 30. After an hour I got him.
Just got mine today. :D I wouldn't go crazy with the camping. just do runs when you can and she will drop :)
I agree that 1 in 200 is off , took 343 attempts but then got two in the next ten !!!
Finally got her after 308 kills, sadly I have no luck with RNG, glad that I finally got this one out of the way, one less pet to grind for :)
Got mine today after 272 kills, all in all took around 5 hours. Compared to most of the pet drops on Timeless Isle, I didn't find this one bad at all, just long. Like others have said, a good way to do your epoch stone and elite kill dailies in the process :)
I will warn anyone farming this pet in advance, the 1:200 drop rate did not pan out for me. I killed approximately 440-460 of the Jademist Dancers before this pet finally dropped so don't be disheartened if you hit 250-300 and wonder what's wrong.
This pet is good to farm while you're completing your 20 rares or your 50 epoch stones as the dancers can meet both quests. Good luck and happy hunting!
just put a level 25 jadem dancer up on my servers ah
A definite go to pet for wiping the floor with elementals! Will take out every trainer elemental in three hits.
I know this old thread but bout 20 min ago was farming for her at 165 attempts
and this hunter there asks me why I'm killing them I tell her for pet. She proceeds to open trade an gives me one , oh joy an wouldn't even take any gold. Just to show I you that there are still good people in wow. Thankim unknown hunter.
Picked mine up on 3rd clear of the beach.
for sure a very powerful pet. I use in a couple teams to 2 man pandaria trainers
This one took me a lot of time, two months of trying. I agree with some of the other posts, best to do this in small quanities. Have been going back and forth between the beach and the cavern. Gotten nothing in the cavern as yet. The Mobs aren't bad one on one but when they swarm you, you are doomed. Seems to be a very low drop rate. The pet is very cute. Quite worth the trouble.
I had really bad feeling about this one since im on Kazzak and the server has super duper high population. Farming on the Timeless Isle can be really frustrating. Thats why I decided to farm this one in small doses. So I started every now and then, usually late at night to have more chanses of finding the Dancers alive. Then I did some farming yesterday evening and some today, in the afternoon. I think overall I have killed around 100 Dancers and finally today I got my tiniy little one =)
This little bugger is so elusive! I have killed over 400 Jademist Dancers and no pet yet. I try to farm during non-peak hours to avoid any competition because the re-spawn is a little slow. I'm not going to give up though, I want this cutie!
Get the 317 speed one. It has no avoidance or much defense, essentially a glasscannon, so it is imperative to be fast. It still hits very hard, so no need to go for power. Rain Dance is an excellent move, heal and hit/crit buff in one go. With the synergy in Acid Rain, 25% bonus damage to aquatic moves, and Steam Vent is incredible. But it also have other nice moves to try out. Only thing is it goes down quite fast.
Finally got one after two full days of farming them! Don't give up!
Today being the one month anniversary for my wonderful girlfriend and me I went farming for these pets didn't have my hopes up because R N G random number generator has never been kind to me. Got him all buffed and set off I went to kill these things about I guess maybe an hour into it one dropped I was like yes my baby gets an anniversary gift battle pet decided to try my luck one more time and lo and behold the second dropped.
