Rather than granting boons and bonus spell points, sphere-specific drawbacks grant the target an extra magic talent in their prerequisite sphere. The prerequisites of the selected talent must be fulfilled. A creature does not gain this bonus magic talent until they gain the sphere-specific drawback’s prerequisite sphere. A sphere-specific drawback may be removed by spending a magic talent, in essence ‘paying back’ the talent gained from the drawback.
It is possible to have multiple sphere-specific drawbacks from the same sphere, but some drawbacks are incompatible with each other. These are listed under each drawback as ‘incompatible’. Occasionally a sphere-specific drawback grants a bonus feat in place of a bonus magic talent. Such sphere-specific drawbacks must be bought off with a feat instead of a talent, and may only be bought off in this fashion if the caster meets the bonus feat’s prerequisites.
You cannot gain sphere-specific drawbacks when gaining a sphere through temporary talents (such as those that are only gained for a single casting or that last less than 24 hours), nor use a temporary talent to buy off a sphere-specific drawback you possess.
