Plant + lightening which also breeds sun dragons
You can't breed a Sun Dragon with a Moon Dragon because they are not compatible.
You have to breed a sun and moon dragon together
I got a Sun Dragon by breeding Fire and a Storm Dragon. I don't know how to breed the Moon Dragon though. I am still working on it.
Breeding a storm dragon and plant dragon together can either get you a sun dragon or a moon dragon along with a lichen, storm or cactus. If it takes 48 hours to breed/incubate then you have either sun or moon. If you keep trying you will get it eventually I did.
You have to breed a storm and fire dragon. ( which might end up as a sun dragon ) or crystal and blue fire. ( which also might end up as a sun dragon ) But there other ways to.
You can try to combos of crystal dragon with bluefire dragon.
48 hours normally
