The Beginners Campaign is an event that affects those from Rank 30 to 100, it cuts and doubles (triples for rank 30~79) several things depending on your rank. For example all of those who are under Rank 30 have a 3x increase in EXP gain and coins, while leveling cost and stamina required to enter a dungeon is decreased by half.

If you are under Rank 100 you should see that some texts in-game flash yellow, that's what has been affected. If not you are out of the scope for this event, as you aren't considered a beginner ^^;
