Hi! Just a couple of questions to clarify.
Will creating a legendary card cost both iron and aura? or just one or the other as well as cinder?

And just to know I'm doing my calculations correctly;
If I want a level 4 Common Water card.
This will cost me 20k Grain x 30 = 600,000 Grain total.
And then for Cinder 30 x 375 = 11,250
11,250 ÷ 1.5 = 7500 CP Total that I would need to burn to get The cinder I need for the level 4 Common Water card?

Sorry if my math is wrong. Looking forward for the release! :)
