I'm guessing there isn't a certain formula where you are garunteed one if you fight him X amount of times. I think it just has to do randomly with luck. Many of the pets that drop from bosses are rare, and you would need to fight them many more times that 12 to have it drop, otherwise it wouldn't be "rare" any more :)
Either way, good luck with your sprite, I hope you get it! :D
i don't mean to be rude but my little brother faced rattlebones on his regular quest and got a myth sprite. The percentage of getting a myth sprite is not very high, and I say a few more battles should get you one.
I have fished the gurtok demon over twelve days watching numerous other people get the spook pet it drops. Just the way it goes. And drops, no matter how burned your eyes are or numb your brains get , is never an earned thing. Its just something that happens.
and there is no easier or harder way to get what you want from a drop. However, if you feel it will help, wear the same socks you were wearing until you get the drop.
It is discouraging watching others seem to easily to get what you want. I hope by the time you read this you will have or soon have the myth sprite.
No glitch. I fought rattlebones on my new myth wizard that I made after my master Ice wizard and I got the myth sprite on the first try! I didn't even need it since my ice wizard already has it. You just have to keep on battling him Lucas Drakebloom Level 40 Ice wizard Oni slayer
