The idea is cool, looks like an advent calendar but I found out about it quite late as I don't check the forums that often anymore. How come it wasn't featured on the news or social media? Maybe I overlooked it by accident so I apolagize if that's the case. I'll try to do the tasks if I'm up for it.
The rewards on the other hand... Everyone needs PEN which is a nice reward and the mousepad is an interessant bonus. However, there are other stuff that can be equally useful to players. Instead of rewarding PEN caps only for the daily tasks, why not give away items in the same context to vary a bit? For example 30%/50%/100% PEN/EXP/MP plus, several gears pieces, enchant bonus such as lucky/jackpot, basically stuff that helps players to experience S4 better. Giving PEN only is so plain for such a festive holiday period, it kinda makes me sad.
