Choose a monster to take care of, train and fight in Monster Arena. Your monster has four skills: power, defense, agility and intelligence. Power determines how much damage your monster deals, defense is the monster's health, agility is the monster's ability to evade attacks and recharge, and the monster's intelligence effects its critical hit rate and accuracy. When your monster levels up, its stats increase and you gain an ability point, which can be spent by clicking on the ability tree. In addition to fighting your monster, you can train it via mini-games and effect its mood with various activities. These activities cost activity points, which you receive every month.
