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
 * Level 31-70 gear items can get: 2% on rare, 4% on epic, 6% on unique
 * Level 71-200 gear items can get: 3% on rare, 6% on epic, 9% on unique

You will need a magnifying glass available from most Potion shops to reveal the potential. There are 4 types, namely Basic, Average, Advanced, and Premium. Basic magnifying glasses can reveal potential items level 30 and under. Average magnifying glasses can reveal potential items level 70 and under. Advanced magnifying glasses can reveal potential items level 120 and under, and Premium magnifying glasses can reveal potential items that are any level.

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 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 or unique 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.

Other possible benefits include: new skills, increase in damage, all skills get extra levels, ignore certain amount of damage by a certain % of chance.

Skills you can get:
 * Glove: Decent Sharp Eyes (self only)
 * Shoes: Decent Haste (self only)
 * Overall/Bottom: Decent Hyper Body (self only)
 * Helmet: Decent Mystic Door (self use only), requires 2 Magic Rocks
