They are unique so I am pretty sure you cannot get duplicate mount, pet, etc. once you have learned them.
But, if you did not learn them (ex. traded it when you first got it), then my guess is that it can drop for you again. However, this is just my assumption so I could be wrong, not to mention the second time will be still RNG.
Characters on same account. I have 1 planted at each spot. Sometimes I get a bag, but otherwise all I get now are the wild cards that exist so they can say they are dropping loot.
there is another thread for the pet although the pet is mentioned in here as well
There is another thread now for the pet and the person claims that has been fixed. I don’t know if the cards were fixed or not. I don’t have much motivation to waste much more time on those since I already wasted 6 hours.
It is what it is. Got the Hearthstone off the rip first Dr Boom spawn. Awaiting the rest, albiet I’ve only done the event 5 times.
(For content my unluckiest was at the end of SL, did the mount run for Taza black gearglider about 1500 times no dice. Stopped grinding as hard since).
Can confirm you can get more than one pet. Just got my second Sarge 45 min. ago.
It is tradable, but not cageable so you’ll have to trade the item that teaches the pet.
they do, mostly. But if youre in VD and kill boom, loot and camp. Then log onto a character in SW quickly, you can possibly get that one. Then log onto a 3rd quickly in Durotar, you can possibly get that one.
And sometimes the timers are off by a minute or 2. But if youre quick, you have a chance to get 2 or 3 Not always, but still a chance.
