Magic items can have 2 Modifiers; a Prefix and a Suffix. Rare items can have up to 6 Modifiers; 3 Prefixes and 3 Suffixes. More powerful and dangerous enemies are more likely to drop rarer Items.

Quality grants small bonuses to an item depending on the type of item, up to a default maximum of 20%. Martial Weapons gain 1% more Physical damage per Quality. Armours gain 1% more Armour, Evasion, Energy Shield and Runic Ward per Quality. Rings and Amulets have a number of possible quality types that provide bonuses to specific modifiers on the item. Flasks gain 1% more Life and Mana recovery per Quality. Charms gain 1% increased duration per Quality. Skill Gems or equipment that grant Skills grant a specific bonus to their Skill based on their Quality.

Essence monsters are powerful monsters trapped in crystallised corruption. Breaking these monsters free allows them to be defeated, dropping the Essence that can then be used to modify equipment. Any monsters with Essences Modifiers drop an additional Essence of that type.
