KIT KEY

At the end of each kit there is a listing of BONUS, REQUIRED, PREFERRED, and FORBIDDEN 
proficiencies.  The basic concept is one that is used throughout the _Complete ... 
Handbook_ series and other supplements, but here is the way that it works IMC: 

BONUS proficiencies are freebies, gained at no cost in 'slots'. 

REQUIRED proficiencies *MUST* be taken when the character is created, costing the normal 
number of slots. 

PREFERRED proficiencies can be taken at the normal number of slots even if they are 
outside of the character's normal proficiency list.  At least half of a character's 
initial NWP slots *MUST* be spent on some combination of REQUIRED and PREFERRED 
proficiencies. 

FORBIDDEN proficiencies are proficiencies that cannot *EVER* be learned by the character 
(with the exception of the case where, for example, "All Rogue proficiencies" is listed as 
FORBIDDEN, but a proficiency listed as PREFERRED or REQUIRED happens to fall within the 
Rogue area.  If this is the case, the proficiency can be taken normally).
