Dragon Mania Legends is a typical phone game in that there are multiple currencies in the game, and one of them is purchased using real money. Their events ramp up in difficulty in what I assume is obviously an attempt to get people to spend money to finish them. And I don’t spend real money on this game.
In this style of events, you go through multiple levels unlocking chests. A chest can contain the key to the next level or a puzzle piece toward unlocking a dragon. (Collecting dragons is the primary goal of the game.) The last level has a chest that will contain the a dragon itself, and this is basically the goal of the event. This event celebrated Chinese New Year, and the final dragon was the Nezha dragon.
For the first time, I was able to get that final dragon! The event ends tonight, and I got it this morning. And yet I did some quick math and found that it would be impossible for me to get the puzzle piece dragon at this point without spending real money. Still, I’m happy I finally got the end dragon in one of these events!
