I'm not sure if this is the right place for this, let me know if there is a better place to ask questions.

My challenge log for Battles has for me to complete 3 Wondrous Tails. I've looked up those but I couldn't find for sure when you can open those up. Do you have to have finished ARR and started the expansion to open those up?

Also, is each challenge on that Battles page separate and it doesn't make a difference if you don't do them all or do you get something extra if you have done them all?

Thanks!
