This means that as you reach a certain level, the modded items will begin appearing in-game, mostly on NPC’s. When you install a new clothing or armor mod in Fallout 4, a lot of them will be added to ‘Leveled lists’. Random NPC’s such as settlers and enemies like Raiders can spawn with these items, making them look more unique, and even harder to defeat if the stats are higher. Clothing items can completely change the appearance of Fallout 4, especially those added to leveled lists (see below).
