Of course you can. I get better with each one I do, and therefore have something more to give to the next person.
25 Lightning
18 Air
20 Earth
28 Plant
39 Cold
39 Water
47 Metal
216 Elements.
25 Blooms and 18 Panlongs leave us with
2 Earth
3 Plant
14 Cold
21 Water
47 Metal
3 Reindeer(Lichen), 2 Iron, 11 Mine & 21 Rust leaves us with
13 Metal. So if we pull apart 4 of those panlongs and make 4 more Rust, 4 more Iron and 4 Chrome, that leaves 1 more metal element, which we'll put into another Iron because of the 4 hour breed time. So totals are:
25 Bloom @ 13 hours = 325 hours
14 Panlong @ 36 hours = 504 hours
25 Rust @ 6 hours = 150 hours
11 Mine @ 10 hours = 110 hours
7 Iron @ 4 hours = 28 hours
4 Chrome @ 5 hours = 20 hours
3 Reindeer (Lichen) @ 5 hours = 15 hours
89 Dragons. 216 Elements. 1152 hours or 48 days exactly.
1.85 dragons bred per day
30 million in DC required per day to keep pace with breeding and feed each new dragon immediately up to Level 15 (assuming your breeding required dragons in one cave and using the other to breed for cash). If you can make more than that per day, you can increase required dragon breeding in one of 3 ways:
[*]Use gems to speed up required dragons
[*]Breed required dragons in both caves
[*]Replace 2 Panlong dragons with a Sandstorm, a Mud and a Fog dragon. This will dramatically decrease you breed time from 72 hours to 16 hours, or approx 1/4 of the time, and means you will need to earn 48 million in coins in that 2/3 of a day.
Any or all of those options are the sort of thing you can do occasionally.
