Explanation for the sheet. At the bottom you see costs for the path and costs to reach the key. The key is always for the next dragon on the list. That means you have to add the costs for the keys of all previous dragons for the dragon you want. For example for Wisdom you need the keys on Taj Mahal, Chimera, Stonework and Solstice: Chimera Key from Taj Mahal Path: 490 coins

Stonework Key from Chimera Path: 1720 coins

Solstice Key from Stonework Path: 2765 coins

Wisdom Key from Solstice Path: 855 coins

All Keys cost: 5830 + path costs 5000 coins. So for Wisdom you need 10830 coins in total.
