How much Aether is used when attacking in an Aether Raid?
Solution 1:
I found the answer,
The First attack each day is free.
Each subsequent attack costs an amount of Aether based on your current Lift : 
This means if you have 3001 to 3100 lift, it would cost 40 Aether to attack.
Also as you progress and your lift increases, it takes more Aether to attack.
