Defend Berk

Battle is a gamemode, It is coming soon.

Gamemode
There is nothing known except that dragons will be battling vikings or dragons will be battling each other. Tapping on dragons and going into their information will show the Battle Mode logo and Coming Soon! beside it.

Trivia

 * Toothless also has a Battle Mode Bar, but makes no sense if you are able to use him as he is the only Night Fury we know of.
