Question for Oct Donation Bonus

[GM-Ciar]

1. If you donate 10$ on any other month, you can select one monster to boost. During October 2017, you can donate 5$ to boost one mob, or 10$ to boost two.

2. Donating 5$ during this year's birthday month would get you 1 backpack. That's basically the same as the bonus from 2016.

Basically, the amount you donate is doubled. 5 -> 10, 20 -> 40, and so on.
