Battle Arena

The Battle Arena is where you can pit your dragons against other player's dragon to earn marks alongside points/ribbons/trophies. However battling does not tend to be profitable until your dragon reaches age 70. Your dragons need to be at least age 20 to battle.

You lose a small amount of marks (50-100+) if you lose but can gain up to 4000 marks if you win. Additionally your dragons can gain 0-2 power each battle.

The outcome of the battle is dependent on your dragon's stats and genes and the opponent dragon's stats and genes with a bit of rng.

Some things that will earn you more battle points and marks
 * Battling dragons around your own dragons stats
 * Battling dragons of the same breed as your dragon
 * Battling equally matched dragons that are also of the same breed of your own dragon.

Ribbons and Trophies
The different colored ribbons and trophies on dragon profiles represent a certain number of battle points reached. Following is the breakdown:

Ribbons
 * Pink: 25
 * Green: 50
 * Yellow: 100
 * White: 150
 * Red: 200
 * Blue: 250

Trophies
 * Bronze: 300
 * Silver: 400
 * Gold: 500

Tips

 * There aren't many players who battle so you might not want to set your battle ranges too small or your dragon might not be able to be challenged at all.
