----------How to get Beserker and Sage (or future 4th tier classes)----------
1 - 2500 JP
2 - 20 x Class specific proof (You can get em from farming EX 4 in co-op, using that class a lot iin co-op for 4 max, or Rose Queen raid, or purchase them daily once per day from HL gold shop)
3 - A title. This is the part confused people. The title isn't from running a class 1000 times in Co-op.
You get this title from :
--Picking a co-op weapon to make, any will do. Upgrade it to SSR, then awaken it, then Elemental change it.
--A new quest will then pop up. Beat it with the class that can equip the weapon you were upgrading. This will get you that class title and UNLOCK and boss battle PERMANENT.
--After that you can just use Weapon Master or Bishop to fight the boss again, to get their own title, without having go through making another weapons again. This will be the same for the rest of 4th tier class.
NOTE: The boss's element will always be your better opposite. So if you're fire element, the boss will be water element.
