Oktoberfest Sale

From now until October 6th, all available promo gachas will be 50% off!
We've also permanently made changes to Promo Gacha drop rates (which means these changes will not revert back after the sale).
Adjustments made:
- Reduced the chance of getting a normal gacha card. (Note that any reduced chance to get something increases the chance to get everything else)
- Increased the chance to get exclusive items.
- Added a higher gem reward.
- Increased the chance of getting set items if a promo gacha contains a set.
