So my treasure dragon just finished hatching and I got 20 for it...
6/960 - Harvest Food
0/128 - Complete the Quest (Im going to get another Air dragon so I can use my epic air in the battle arena if I need to)
20/128 - Hatch Dragons
Just harvested Scalypears, got 20 from each crop. Maybe i'll stick to this since it's less hassle.
I just harvest 3 diamonates and got 15 total but this summoning is going to be tough
First you need to put in the quest. It is the bottom option, 4 hour - I think it is the air dragon. Make sure you get it out in 4 hours time, then repeat and so on.
Put food in all your farms. 5hr and 20hr have worked best in the past - just make sure whatever you are putting in you can get it out in time and re-plant. To get all the parts, usually you have to be very timely for the whole 10 days.
For hatching, make sure you are always breeding something to go on the nest. Even better if you have two nests. If you have a spare nest, you can buy a water dragon in the market for coins which should give you drops too.
Keep reading the thread to see what other people are doing to meet the targets.
Good luck.
