From now through August 8th, MU Online players can join Speed Event Server Season 2 for a whopping 20,000% increased experience. In addition, players will receive items to assist in leveling if that amount of experience isn't enough.
Once the event is complete, players will be eligible for free transfers of these boosted characters to the normal servers, though the special "activated buff" items will be removed.
To celebrate the arrival of Speed Event Server Season 2, the MU Online team has organized many special in-game events. During the event period, players can enjoy level-up rewards, ranking rewards, free gifts of [Bound] Bless of Light (Higher) x 10 & [Normal] Scroll Package (3 Days), and many more rewards from Captain Marlon's Mission Event.
