The Task System can now be accessed directly from the game client. Simply click the "Tasks" button located in the tabs below the inventory (on the right side of the screen).
At the moment, rewards consist exclusively of experience (EXP). Once the required number of creatures has been defeated, the player will automatically receive the configured EXP.
If the player is in a party with shared experience enabled, monster kills are divided equally among all party members. For example, if 1 creature is killed and there are 4 players in the party, each player will receive 0.25 kill progress toward their task.
