Upgrading

Upgrading is an essential part of your character's growth. (Minimon OR Hero). It enables them to reach the next grade, and also makes them stronger by this process. To upgrade a character, you must sacrifice another character of any element or grade. The maximum required upgrade level depends on the character's grade. The higher the character's grade, the higher the cost when upgrading. The cost is fixed for each grade, no matter the grade you are sacrificing. Each slot filled to sacrifice will significantly raise in price. If an upgrade fails, a small percentage will be added to your success rate total along with some of your gold spent. When that happens, it's best to play around with sacrificing a mixture of smaller and higher grades to save characters with a higher grade for a better success rate at future upgrades.
