I bought 2 stars for 20 gems earlier today to raise a Saint with 2 stars to 3. Had a 72% success rate. But failed like always... And of course took a star away from the characater as well... So 20 gems to lose a star. Now it would cost how many gems to get that star back and get to where I started? They REALLY need to make it so failure DOESNT take a star away from the character... Spending 20 gems to lose a star is rather ridiculous. Now it would take 20 more gems to TRY to get back to where they were at 2 stars... Then another 20 gems to try and get a 3rd star again... Thats obscene...
