Path Of Exile - Guide - Quality Basics

Quality applies to armour, weapons, flasks, gems and maps; in short, all equipment aside from amulets, rings, belts, quivers and jewels. It always varies from 0% (at which point it is not displayed on the item) to 20%. Each item type has a currency item associated with it to increase its quality. Quality can be an extremely important method of improving items, as it does not affect the requirements for using an item or the mana cost of skills.

All items are capped at 20% quality and each currency that affect quality will improve normal items by 5% each, magic items by 2%, and rare and unique items by 1%.
