Competing

To choose a dragon to compete, touch the to view the event screen. At the top of the screen is the event type.

Remember, after placing a dragon in the it cannot be removed for 24 hours and the event cannot be sped up using gems or Kairos. The dragon in the does not earn income in its habitat during the event.

Trophies
Trophies are awarded based on your dragon's "performance". Factors that may increase a dragon's performance include:
 * Dragon Level -- the higher the level, the higher the chance for a Gold Trophy
 * If the dragon chosen for the is a pure element dragon the chances of getting a gold are said to be even higher.
 * If the Dragon Placed in the Colosseum is a limited dragon, the chances of gold have been speculated to be higher.

Nothing guarantees a Gold Trophy. A dragon may receive a Gold Trophy one week, and only a Silver Trophy in the same event the next week.

On the "TROPHIES" button, you can view past events: which dragon participated, the date and time of the event, and the award type. This is very helpful as it shows which achievements you have left. However, if a higher-ranking Trophy was acquired, then only the most recent dragon that obtained that same-ranking Trophy (or higher if a Silver was acquired) would be recorded. For example, if a dragon acquired a Gold Trophy for one element for one day and acquired a Silver Trophy for that same element on a later day, only the date when a dragon acquired a Gold Trophy would be recorded.
