MapleStory/Potential System

The potential system is a bonus to item stats previously set. If you pick up an item, there might be a notice in your chat window saying, "You have found an item with hidden potential." If the item has a red outline, it means it has hidden potential. If the item has a blue outline, it's a rare item. If the item has a purple outline, it's an epic item. And if the item has a yellow outline, it's a unique item.

There are 3 tiers of potential items:
 * Level 1-30 gear items can get: 1% stat bonus on rare, 2% on epic, 3% on unique, 4% legendary
 * Level 31-70 gear items can get: 2% on rare, 4% on epic, 6% on unique, 8% legendary
 * Level 71-200 gear items can get: 3% on rare, 6% on epic, 9% on unique, 12% on legendary

You will need a magnifying glass available from your inventory to reveal the potential by paying mesos. It will be free if your Insight traits allow. Level 30+ for level <30, Level 60+ Insight for equipments level <70 and level 90+ Insight for equipments level <120.

Items with potential will have either 2 or 3 lines of stat additions. This can only be changed through the use of a Premium Miracle Cube, which has a 25% chance of changing a 2 line item into a 3 line item. Miracle Cubes and Premium Miracle Cubes are NX items that are used to make a rare, epic, unique or legendary item return to the hidden potential item status. It also resets the stats and the potential class of the item, making it able to remain the same status or reach a higher one. Once an item reaches epic status then it will never go down to rare, and once its unique, it will never go down from that status.

Any of the following stats can be improved through potentials: INT, LUK, STR, DEX, HP, MP, Accuracy, Avoid, Defense, Magic Defense, Speed, Jump.

 * Glove: Decent Sharp Eyes (self only)
 * Shoes: Decent Haste (self only)
 * Overall/Bottom: Decent Hyper Body (self only)

Potential Scrolls and Advanced Potential Scrolls can be used to add a potential to an item. They have a 70% and 90% chance of succeeding, respectively. However, they will destroy your item if they fail. 80% Epic Potential Scrolls can be used too and passes at a 80% rate. Destroys at a 20% rate when failed.

Additional Potential
You can get extra potential on equipments now! However, the stats boost are far worse than normal potentials. It is very hard to raise its rank and only some equipments can reach a stats boost with the exact same amount as normal potentials. They can only be resetted by Master Additional Potential Cube.
