If you install the
install the Spellbook Builder Plugin for Mage Wars from the Plugins Menu run Validate Mage Wars Spellbook. A window will pop up with how many points you have spent. Additionally that spellbook is copied to your clipboard. If you open up your favorite text editor and paste, you will see the contents of your spellbook in this format:
Quantity - Spell Name - Spell Level - Spellbook Cost - Total Spellbook Cost
The cards are sorted in to spell type and one day I hope to add in how much has been spent per spell type.
Let me know if you have any other questions.
