Sphere-specific drawbacks must be chosen when a practitioner first gains the associated sphere, and grant the practitioner an extra combat talent in the prerequisite sphere. Drawbacks may be removed in place of gaining a new talent through your class progression or by taking the Extra Combat Talent feat.
Wiki Note: If a Base Sphere grants an additional talent (such as via a package selection or drawback) the additional talents do not count as talents spent for abilities that count the number of talents spent in a sphere. (This most often applies to gaining skill points or improving unarmed damage.)
Utility Starts
The [utility start] tag is described in Spheres of Guile. It is only possible to take advantage of a combat sphere as a [utility] talent if your game includes a way to gain combat talents restricted to those with the [utility] tag, such as using one of the variants in Chapter 1.
Piecemeal Utility Starts: If you have a progression or optional replacement that grants a [utility] combat talent or a [utility] magic talent, you can use it to gain a base sphere if you apply a drawback or combination of drawbacks that removes all of that base sphere’s benefits other than skill ranks and [utility] talents (and actions necessary to use such talents).
