An Upgrade Module is an item added in Shadowkeep that allows for weaker weapons and armor to take on the power level of a stronger weapon or armor. However Upgrade Modules can only be used to infuse weapons that are of the same equip slot and armor that is in the same equip slot and of the same class (Ie, you cannot infuse a Warlock cloak into a Hunter chest plate or a power weapon into a primary weapon). Upgrade Modules can be obtained by purchasing them from Banshee-44 or Ada-1 for an Enhancement Core; 10 Legendary Shards, 5,000 Glimmer, and 25 Planetary Materials or from the Spider for a random deal that changes daily. They are also randomly dropped from killing bosses when a Finest Matterweave has been consumed. In addition to these ways, there are certain perks that can be added to a leveled up ghost shell to obtain them when completing playlist activities.
