I'm really lost. I haven't played this game in years. How do I breed them? I have a level 20 shark dragon and a level 20 fire dragon, but they won't breed. Can only certain dragons breed? And what are the egg drop rates in adventure mode? I've been playing for like 3 days and haven't gotten a single egg!

If there are any grammatical errors, it's because I don't speak Korean. '^^

I'm using a translator for all of this!

As a returning player who's familiar with DV2, I'd like to ask for some advice! Thanks in advance!
