Mage spell costs
I was trying to figure out what spells to buy, so I could minimize my gold spend. It wasn't very easy to find the actual costs in a useful form so I created a Classic Mage Spells spreadsheet. It's taken from vanilla-wow.fandom.com (so might not be perfect).
For example buying EVERYTHING will cost 212g which was honestly a surprise to me. Even more surprising was that all spells up to level 40 will cost a significant 56g.
Not sure how I'm going to handle this just yet but if I want my mount at 40, watching my spend on spells is going to help.
Here's a chart of the total gold spend.
This is just a rough tool. Please comment with any mistakes or suggestions.
