Modifications are a specific class of Item which can modify Weapons, Wearables or Equipment, providing positive (and/or negative) effects.

Modifications are typically produced and installed by Engineers with the associated skills (Weapons Tech, Wearables Tech, Equipment Tech).

Many Modifications have specific installation requirements. These requirements often stipulate what type of Item is being modified, but may also be tied to specific Item Manufacturers. High-end Modifications tend to only be compatible with Items manufactured by specific corporations. 

The installation or removal of a Modification should be performed through a minimum of five minutes of suitable roleplay. The modification should be attached to the Item card.

Only one Modification may be equipped to an Item unless the Item or another in-game effect states otherwise.

Modifications do not typically require upkeep or maintenance, except when RENDED, or another in-game effect requires it.
