If you buy 800 gems for $30 on the gem discount sale. You can get 3 monsters (300 cells) for 747 gems. To buy 6 chests (300 cells) is $30. So for a good monster like Saulot or Stormbeard it’s a decent deal. For Mishka, eh I have a bridge to sell you in Brooklyn 😀
I also like that it’s just pay and you get cells, no jumping through hoops, hoping for a sale or a cell pack offer and the numbers work.
