Note: Event is only available to LV60+ characters.
Speak with the Physician in the area that corresponds with your LV to receive a 24-hour timed quest. Defeat as many of the designated monsters as you can within the time limit. For every monster you defeat, the amount of EXP that you will be awarded upon completion of the quest will increase.
The amount of EXP awarded at the end of the quest is roughly 50% of the normal EXP given per kill.
Note: The quest may be completed manually by speaking with the appropriate Physician before the time runs out.
