User blog comment:Metzo89/How many Crystals do you need to get all Treasures?/@comment-24995069-20140817155508/@comment-25247843-20140817162256

It took a couple of hours (some of them just for writing the article), but because of this wikia, there was much less work, because I found the information about Crystal Costs all here. :) That was a huge help!

Collecting Crystals is time consuming, but with the amount of events where you can earn Crystals, there's a better chance to archieve this goal. When you are at a point where you have all Pets and Cookies bought, it will be easier. You no longer need Crystals for other things, you can get more Crystals during these mission events (cause you can do all missions and get the most Crystals) and with thze Level 50 Trophy (or other Treasure with Power+) there is a chance to get more of them by luck.

So don't give up the hope :)
