Mods

M.O.D.S (Magical Offensive Defensive Subroutines), or simply "Mods" are passives on equipment most of which can be moved to the same Slot Type, eg. Helmet to Helmet, Weapon to any Weapon, but not Helmet to Boots. Mods can be found throughout the game, with more available in higher difficulties.

Quality

Mods come in a ten-tiered quality system also known as the "Qualibean".

Differences between the first nine are mainly marginal. However, the difference from the Ninth to Tenth Tier quality is quite significant as the latter tier will allow the mod to reach the maximum stat value when it's in Chaos VIII tier.

Armor Mods

Mods for the 4 Gear Slots (Helmet, Chest, Gloves, and Boots), which have the Chip suffix. Their effects are additive between each Slot.
