Im missing 3 pets from the Timeless Isle. Was pretty lucky with all the others, but of course the RNG curse of the doom is back on me. Farming this one for days, cant tell how many times Ive killed this thing (and I would add: being killed so many times for that stupid pvp coins) but nothing. And the best part is when you kill it and the guy next to you just drops it like this. =(
Well, keep trying and trying...
Finally got it today after 175 kills! Hopefully blizzard will make it up to me for the awful RNG on the next pet I go for.
For anyone who doesn't know: Jadefire is on the good ol' timeless isle 30-60 min spawn timer. When you kill him, it's best to mark down the time somewhere, run off and do other fun things, and come back when the 30 minute mark hits.
Killed her over 20 times on Wednesday and nothing! Following day killed her once and it dropped! She's gorgeous too!
The drop rate on these new pets is ridiculous, I've killed this thing over 40 times and still no pet.
I've gotta be around 30+ kills on this thing in the past week...and still no pet. Worst drop rate out of anything on the Isle, and to add insult, it's on a very inconsistent ~50 min. spawn timer. To make matters worse, it's a barely above average battle pet...oh and thank god Fade got a CD.
I've been camping this rare for days now. There are more spawn points than mentioned. He will appear at a couple of locations in the front room; at either end of the "ramps", the alcove mentioned and also at the top of the spiral ramp deep inside the cave. You can stand on the first set of ramps with mini-map at max range and see the rare icon spawn in all of those locations.
Like many of the other pet rares, the Jadefire Spirit that this drops from respawns on a 30-60 minute timer. Never less than 30 minutes, never more than 60 minutes. Camp the cave until it spawns, kill it, then go do something else for half an hour. Horrible drop rate, so expect to do this for a few days.
You can kill all the non-rare elementals in the cave while you wait if you feel like it, as they also drop a pet. It can be a good way to kill time while camping.
People who are using this pet to try to get people to forfeit clearly have nothing else better to do. They'd rather sit and wait 30 minutes for someone to forfeit before accepting their LOSS. I'm a natural, stubborn taurus and don't let these crappy pet trainers win. /flex [; I'm 100% sure that Blizzard will have this pet nerfed soon!
The 'fade' ability on this pet with no CD has got to be nerfed. Was PvP pet battling this morning, took out my opponents first two pets, then sat there for almost 40 minutes - literally 273 rounds, while the guy used 'fade' (which always goes first regardless of pet speed) over and over making his pet unhittable. After the first 10 minutes of this I was going to be damned if I surrendered . . . and 30 minutes later he finally gave up. Really bad planning on Bliz's part with this one :P
After about two days of farming around every hour, this little baby finally dropped for me while farmig Jademist Darters with my boyfriend. Very pleased my friend told me she was up so I could grab this little bugger. =3 I'd say the spawn timer is about 30-45mins.
Very lucky and got this first time I saw this rare, I love it so much! He was in the front room :)
I was lucky enough to get this pet on my first kill. He was in the first area at the entrance to the cave. Good luck everyone!
The rare actually spawns in at least three different places in the cave--in the front room, in the back by the big fire, and then in one of the side rooms in the back right (looking at the map). If you don't see him in the first room, he might be farther in :)
Got mine after 4 times seeing it spawn, first time it died before I could hit it
number 4 dropped the pet.
I find it a slow respawn timer :)
Drops from Jadefire spirit, a Rare who spawns inside the first room in the cave. Only seen the rare once since launch so idk if he comes out less often then most
