Guild Wars 2 Giveaway: Trivia #23

Guild Wars 2 giveaway continues with the 3rd challenge of Quest 10. For the 10th time, a DevilsMMO.com reader will win a free copy of this fantastic MMORPG. Today's challenge is a little bit tough, maybe too difficult for those who just joined us, but oh well, only one will win a copy of the game and we need to have tough challenges every now and then.
