How to duplicate your Dragon Village Account:

1. Get another phone or android tablet.

2. Download Dragon Village to it

3. Enter your existing name and password.

Your new android or tablet will now be a duplicate of your account complete with all the dragons, cards, diamonds, items, and elements. You can then play and each system will be different from then on.

You can then try out more dragons without using a "have more dragon".
I suppose you could also send all the elements to a third friend.

Dragon Village Korean hack

If you play Dragon Village and switch your Android phone over to Korean as the default language there are two more buttons available when you visit the Fortune teller.

The place to combine attack, defence, and life jewels stays available instead of disappearing after a few uses.

There is also a code entry for item cards you get when you buy Dragon Village card packs at the store. These card packs are only sold in Korea as far as I know. However I played Dragon Village for a month and never found a +22 health even in the dungeon. However I bought a pack of cards and got an item card with one.

Another thing I found while playing in Korean was a snow particle. You can combine 10 snow particles to make a buff drink. Maybe I am unlucky but I never found one of these while playing in the English version.

A word of warning though. When I switched my phone over to Korean and played Dragon Village my Book of Dragons was erased.
