Potential & Cubes

MapleStory's Potential system is a way to greatly empower your weapons and armor beyond their base stats. Potentials add an additional 2-3 lines of stats to an item. If you're not happy with the Potential stats, you can use Miracle Cubes to reset the lines and get new stats. Additionally, the higher level the item, the better stats you can obtain. Not only that, there are 4 levels of Potential that an item can have. It is easy to see why it's called the Potential system.

Potential bonuses are determined by a shared pool. For example, if your item is Epic level, the stats determined upon cubing can either be Rare or Epic level stats. If Unique, stats can come from either the Epic or Unique pool, and so on.
