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).
Cautious Fire
You do not gain the barrage ability and cannot select (blitz) talents or other talents that rely on barrage. You gain Close Combat Specialist with this drawback.
Defensive Shot
You do not gain the barrage ability and cannot select (blitz) talents or other talents that rely on barrage. You gain Intercepting Shot with this drawback.
Incompatible: Cautious Fire.
Distant Looter
You do not gain the melee archer ability. You do not treat Point Blank Shot as an associated feat, and cannot select this drawback if you gained the Barrage sphere instead of gaining Point Blank Shot. You gain Battlefield Scavenger with this drawback.
Incompatible: Wild Shooter.
Wild Shooter
You do not gain melee archer, and instead suffer a -1 penalty to all ranged attack rolls. You gain Suppressing Fire with this drawback.
