This is one of the reasons leveled lists exist. Unlike the PC, there is no intrinsic mechanism for an NPC to gain perks as they level a stock leveled NPC has the same perks at any level.
Note that 5 points per gained level are always added to Health, in addition to any health points from the shared set of 10 attribute points this means NPCs gain 15 attributes per level, in addition to approximately 8 skill points per level (see below). These weights determine how many of 8 skill points and 10 attribute points per level are added to each value. The numbers in the table are the weights assigned by the classes to each skill and each attribute (empty cells have a weight of zero).
