Parameters

Several factors go into the calculation of damage in Sword Art Online. Among them, include the efficacy of hits (a direct hit as opposed to a scratch), the skill level of a player, the Sword Skill used, and the weapon stats. SAO's damage calculation system is more complicated than the system on ALfheim Online.

Weapons have the following enhancement parameters that determine stats: Sharpness, Quickness, Accuracy, Heaviness, and Durability. When a weapon is given to an NPC or player smith to upgrade, bonuses such as +1 or +2 are appended select categories. Players use an abbreviated notation to describe the effective bonuses on a weapon. «1A2H1D» for example, has +1 Accuracy, +2 Heaviness, and +1 Durability.

On a regular basis, these parameters cannot be seen unless a weapon is «Appraised». Selecting a weapon will only show its name and its aggregate bonuses (the sum of all enhancement parameters). [/hider]
