Ok, so I'm playing dragon city and in the description of an apocalypse dragon, it is noted that it is almost impossible to breed these dragons. Is there a sure fire way of breeding one of these dragons? If so, what two dragons do I need to breed?
There are quite a lot of combinations possible. Its too much work to describe it all, so I'll just post the best combination, and the link where you can find them all.
The best combination is breeding an Abyss and a Double Nature. That way you have %22.20 chance to get an Apocalypse Dragon.
Combinations are virtually everywhere. You need a Level 3 Breeding Sanctuary to able to breed an Apocalypse Dragon. According to Dragon City Wiki, it says:
The most powerful of the four-elements-dragons, he spells the end of an era! With his combination of four opposite elements, the Apocalypse Dragon is pure destruction – albeit unintentionally. He is so difficult to breed that you may never see one.
Your chance are small but getting that dragon will mean total destruction to your opponents in both swagger and battling! Keep trying with different combinations to find out. According to the Dragoncity Guide, the top three most likely combinations for successfully this dragon is:
Archangel + Abyss - 24.49% Chance, Parents >= Level 9, Sanctuary - Level 7, Expected Time: 77:30:00
Double Ice + Abyss - 23.53% Chance, Parents >= Level 9, Sanctuary - Level 7, Expected Time: 75:45:00
Dragonfly + Abyss - 23.27% Chance, Parent >= Level 20, Sanctuary - Level 7, Expected Time: 73:07:30
Looks like you really need an Abyss Dragon to get the best bet on the Apocalypse Dragon! At least a Level 7 Breeding Sanctuary, time, and perseverance to get that dragon. I hope you get your Apocalypse Dragon and this answer answers your question!
