This is an AUCTION. Meaning you can bid on the dragon you want, but others can bid higher and try to get it too.
The starting bid for each creature is 60 points. And must add at least 10 points each time. If someone outbids you, I will hide your comment so that the highest bid for each creature is showing. (Though I will also update the description.) If you want to "AUTO-BUY" a creature before the auction ends, it's 850 points
