Obtaining and Upgrading Heroes
Heroes are obtained by exorcising devils. The heroes you can get this way range from 1 to 5 stars. Training of heroes goes up to "6 stars" where the 5 stars turn orange. Heroes can only be trained to a certain level depending on their star. Luckily once they hit the level cap of their current star they can be upgraded to the next star. For that you need to go to the barracks and push the "Evolve" button. You are then asked to click on a number of heroes that have the same star level to sacrifice them for the evolution. The number you need is equal to the number of stars the hero currently has.

Types of Heroes
There are three types of heroes: During a fight you can see how they interact with each other in the upper right corner. Attacking with a type advantage means you deal 20% more damage while attacking with a type disadvantage can result in glancing hits with a 50% chance which deal 50% less damage and have a 50% chance not to inflict the status they normally would.
 * yellow - Tank, advantage against blue
 * red - mage, advantage against yellow
 * blue - weapon damage dealer (not sure what to call it), advantage against red

Skills
Every hero has 3 skills they can use (except Cailien which has 4 for some reason). There are active and passive skills. Active skills are, as the name suggests, skills that you can activate during the fight while passive skills are in effect as long as the hero is alive. Who would have guessed, right? Each active skill also has a cooldown before it can be used again. Some heroes have more than their default skills. You can change their skills for the cost of evolution coins. For more info on skills see each heroes respective page, the combat page or the ressources page.
