I need to know if i need two of them, If i use it for the challenger will i need another one for my wardrobe for the background?

Yup, they disappear when you unlock the challenger.

oh wow, that blows. :( thank you for the info dear :)

one copy will be used up if you want the challenger, so you will need two copies if you want to wear one.

This challenger beats the snot out of my well-equipped t13 pet who is ranked 80. It's really tough.

wow thanks, i was wanting to know for the future..lol, dont have a pet yet that can do it, but one day i was hoping...lol want the items that are from beating it..but now that you say that, I guess i should just keep the one i have now and not worrie about it. not a big battle person. just do it for story lines..lol
