3/10 Gem Event COST!

Hey guys, I went on the European server to find out about the new gem event which seems crazy to me! The lowest gem you could redeem as a reward is the lvl 5 gem! Now, I just wanted to calculate how much it would cost to use balens to craft these gems
Lvl 5 Gem = 5440 Balens

Lvl 6 Gem = 21,760 Balens

Lvl 7 Gem = 87,040 Balens

Lvl 8 Gem = 261,120 Balens!!!!

Of course, you can always save up your gems, but this would be more time consuming. Though it is usually what non-cashers such as me would use, so I will think about it.
