MapleStory/Traits

Traits go hand in hand with professions, since three of them are directly linked with progression made in crafting skills.
 * Diligence increases as you craft (create something through Accessory Crafting, Alchemy, or Smithing) or as you smelt ores/ turn seeds into oils. Leveling up Diligence increases your chances of having bonuses when using scrolls as well as receiving double craft mastery when you craft at a chance (excluding Level 10, Master Craftsman and Meister level mastery).
 * Insight increases as you mine. Leveling up Insight increases your Accuracy, Avoidability, and ignores monsters' Elemental Resistance (such as Physical resistance, Ice resistance, etc.), as well as letting you reveal equipment of higher levels for free.
