The Summer Festival is back and there are some really awesome rewards available this time. If you were around for this event last year, you probably already know that the least reward you can get for participating here is a blue mount that can run at +80% movement speed. All you need to do is claim your daily Favor of Sune.
This year, however, you have a chance to get a Legendary mount (of course, the chances are probably extremely low). In my opinion, this event is worth farming regardless.
Aside from the Legendary mount, The Summer Festival also offers some rank 7 enchants and a really cool fashion set.
