ArenaNet has a special event going on this week where for all the world bosses that you complete, you’ll get an extra chest with some goodies inside. Some of the goodies are rare auras (appearance items) which have a chance of dropping. I poked around for a bit trying to get a good drop or two, but none happened my way (RNG forever my friend).
That’s alright, I was more than happy with the extra rewards, since I was going to be doing boss fights anyway. I try to get them all done at least once a day. Sometimes it doesn’t work out that way depending on how much free time I have, but I make an attempt.
Happy gaming, no matter where you find yourself!
