HOW DO I BREED A SUN DRAGON!!!!!!!!!!!!!!!
Try these combos:
Cold + Hail Cold + Storm Hail + Lightning Hail + Storm Lightning + Storm
If you don't have these, just use Cold and Lightning. But be warned, all of these only have a 3.5% chance of getting a sun dragon. So it'll take a few times.
Basically you need the elements cold and lightning. You can breed a paper dragon with a copper, and you would still have a chance of getting it (although this combo would have a very small chance). BTW i got mine using storm + clover while trying to get the celtic. :)
