RECRUITING 

When the required building is built,  A Leader can attempt a Loyalty check. If successful, 1 NPC Class joins the ranks. BP costs the first month recruitment begins (rounded up). Additionally if using the Kingdom Point System the Leader may spend 2 KP to actively Recruit 1 NPC Class joins the ranks.

Training

Besides battling,  NPC Class can be trained over a period of time resulting in level increase. Each time the NPC  is trained for the specified period it will result in a level increase and therefore a CR increase. Leader can spend 1 KP to train an existing NPC. The Leader must be a class of the representative class in order to brian the NPC. 

When the NPC levels up,  they gain a level in their class, increasing their CR, but also increasing its consumption by 1 for every 2 CR's of the NPC starting at 3rd level. All new NPC's start out as a 1st NPC class. 

The amount of time (weeks) it takes to train NPC's is same as troops. The Leader must spend 1 KP each week, for the designated amount of weeks in order to train NPC's. 

ADVANCEMENT 

All initial recruits NPC's  are 1st level of their class (CR 1/2). After their first training is completed they gain an additional level in that class(increasing their CR by 1).

This can be repeated for each NPC as often as you would like - but continues to add to the standing cost.

CONSUMPTION 

Once an NPC has a CR of 2 or more, they begin to require upkeep of 1BP per month. This represents supplies for the NPC, housing, and salary. If NPC's are organized into an Army (of equivalent CR) then the regular Army cost superseded this one.
