You slowly gather monsters and resources such as Zel and Karma to slowly build your own army of mighty summons.It is currently available on mobile built on Android and iOs. You may download it from Apple Store, Google Market or Kindle Fire.
April Fools' Day: In 2014, there was a special dungeon that opened up that involved Burny and Friends (who are pretty much the weakest enemies in the game) taking over the Adventurer's Prairie. If you completed said dungeon for the first time, you would get a special Sphere. But the dungeon was anything but easy, seeing as how Burny and friends kept attacking you multiple times and pretty much had the health of a powerful boss.
Area of Effect: Although most units have Brave Burst affecting the entire side, most bosses are able to damage their entire opponents at once. This also especially applies to some of them whole Brave Burst involves healing or supporting their team instead.
Ascended Meme: Previously, Burny was blamed for the servers' overload. And now, we have a special dungeon, dedicated to it and its friends.
Bishōnen: Most male human characters fall into this trope.
Bonus Dungeon: There are two, currently. Each are unlocked by finishing their main area. Technically, the entirety of Cordelica was this, but now you need to finish it in order to unlock Lizeria.
Bribing Your Way to Victory: In the form of Gems, which you buy with real money, and are used for such things as recharging your gameplay energy, acquiring rare summons and instantly reviving all your fallen summons in the middle of battle. Needless to say, players who can afford to pay for gems enjoy a great advantage over those who can't. It is possible to acquire gems for free in-game, but these come very few and far between.
Color-Coded Elements: For starters, all units have their icons' borders colored accordingly. Otherwise, some of them have matching coloured clothes to their respective elements, if it's not themselves being colored.
Crossover: The global version-exclusive Battle Maidens are all borrowed directly from Puzzle Trooper, another mobile game developed by Gumi Inc. They're given different names, but otherwise remain identical their Puzzle Trooper counterparts.
Gradual Regeneration: Some unit's Brave Burst allows regeneration for HP. Without them, your unit may alternatively regenerate the HP as well as their BB themselves through Heart and Battle Crystals respectively. They are produced from occasionally attacking enemies.
Luck-Based Mission: Since whether or not a defeated enemy gets added to your collection is based entirely on chance, any venture in which your goal is to acquire a specific unit inevitably becomes this. It gets especially grating in cases where getting the monster you're looking for to even show up at all is in itself a Luck-Based Mission, since the order of enemy formations that appear in the various dungeons is also completely random. Basically, you'll get what you want when you want it if the game happens to be in a good mood.
Mons: They are in a form of summons. They may be either collected in a form of defeated enemies or obtained through Honor Summon and are usually used in battles, if not as a fusing or evolving ingredient.
Mutual Disadvantage: Between Light and Drak elements, they are the weakness examples, as their attack deal more damage to each other.
No Mouth: Most of the human(oid) character designs lack a mouth.
Outside-Context Villain: The final bosses of each world (as well as a former special event boss) are not obtainable units. You wouldn't even acquire the few exceptions as themselves, only in a form of another kind of unit.
