==Specialties and Extensions==
A specialty is a chosen within a skill or subskill.  Spending one point on a specialty does not improve the main skill, bu adds 2 skill levels within that subdomain.  One can have a specialty in a skill without taking the base skill.

An extension is an area related to but not included in a skill or subskill.  For example, Alchemy, Chiurgy and Natural Science don't cover the study of poisons very well – they might help to create a poison, but wouldn't tell you about how to deliver one.  To have skill in poisons specifically, take one of these skills and spend a skill point for an extension.  (An extension always has the same value as the skill it's attached to, unless it is also a specialty.)

When evaluating the skill pyramid, look at the number of points spent on a skill, not its level.  In other words, extensions and specializations count.
