Perfect is a term used to describe items that have maxed out stats, upgrades,
or even the requirement. For example, a Sword Pommel of Fortitude has a
Perfect HP value of +30. This can also be used to describe the inherent damage
mod that a Rare item will usually get. For example, a Rare Fellblade may have
a Perfect inherent damage value of +15% Damage While Health is Over 50%.
This value is the maximum damage mod that can exist on a weapon. Others can
include +20% Damage While Health is Below 50%, +15% Damage While Enchanted,
and more.
