Hi gmalex, i did not receive mw30 upon completion of the requirements i'd tried talking to my statue multiple times but to no avail @alex
You do have Maple Warrior 30. You just don't have any SP to put into it. Hover over your Maple Warrior 20 skill description and you'll see that the Master Level is 30. You'll need to buy SP resets to reset SP from another 4th job skill into your Maple Warrior skill.
