So I was wondering about 3 things:

1.How much food do I need to get a dragon to level 70?

2. How mamy orbs do I need to get a dragon to 5 stars?

3. Since there is a dragon that can produce food, will he give a food item on a heroic race(just like the green house)?

1. 112.8 million
2. 2000
3. no
