Q: How to get family battle-stones?

[Cabadath]

I do of course know that battle-stones can be aquired by the following means:
1) Family-specific battle-stones from daily pet battle bags - upgrades to rare quality
2) Generic battle-stones from wild pet battles - upgrades to rare quality
3) Buying generic battle-stones - upgrades to uncommon quality

The thing I am wondering about:
What decides which family-specific battle-stone drops from daily pet battle bags? Is it possible to farm specifically for a certain family battle-stone?

- The master pet tamers first pet? Second pet? Last pet? Random but restricted to the family of the master pet tamers three pets?
- The pet you use to kill the first or perhaps last of the master pet trainers pets? Random but restricted to the family of the pets in your team?

Prior to 5.1 I farmed up a lot of bags, and I got 2 flying stones and 1 dragonkin stone.
- I don't know which master pet trainers bag gave me the respective stone.
- I know that I didn't use any flying pets when getting those bags.
- I know that I used a dragonkin in every single battle I got those bags from.

Perhaps it is as simple as this: 10 % chance of getting a battle-stone from a daily bag. The chosen family is completely random, and as there are 10 pet families it is a 10 % chance to get the respective pet family. Roll a D10!

I have only read about the existence of the battle-stones, but haven't seen anything about how the family specific battle-stones are decided to drop. Maybe I haven't been thorough enough in my research, but I hope that someone can enlighten me.

Thanks on front

The stones from tamer daily bags are random. I've gotten an undead stone from the tamer in Krasarang Wilds, for example, when neither he nor I used undead pets in the battle.

I'm not certain about how battle stones fuction with wild pets. My understanding (and personal experience so far) was that the stone would be of the same family as the primary pet you engaged in battle with. That said, someone here on the forums said they got a mech stone from the Water Wavelings in Zul'Drak so not sure if that was a bug or what.

So far, I've gotten quite a few stones off various wild pet battles, and only one from a tamer bag. (And I usually do them all each day ) RNG seems to favor me when I'm out in the wild I guess.

But I haven't found any pattern to the type of stone that drops. I've gotten stones from a family I wasn't battling and one flawless from a Bandicoon group. I call random. (unless someone knows something I don't)

If I had to make a guess, I would say I see one random stone drop in every 20-30 wild pet battles I win. But that's just my observation however.
