|Max. Hero Level||20||40||60||80||100||120||140||160||180||200|
For example, if an Executioner has reached the 4 star level-cap of 80/80, it requires 105 fires to promote him to a 5 star 80/100; the higher the level, the more flames required for promotion. Note that fire does not decrease after being "used." It is more of a requirement rather than a used resource. The maximum amount of flames you can get is currently 780 ((130 regular dungeons + 80 expert dungeons + 50 insane dungeons) * 3 fires each). The number of flames received can be seen in the top right corner after clicking on the Dungeon icon.
