In DragonSky, you can participate in defeating the Legendary Boss while competing for the highest dealt damage against other players.
While defeating Legendary Boss, you can gain the Life Stones as the rewards. Life Stone is a very rare currency in the game, which can be used to upgrade your Goddess.
Every 7 hours, you receive a free entry ticket to raid the boss. You can hold up to 2 tickets at once.
Players can also purchase the tickets using Gems.
