This works identically to Extra Option, above, except that instead of granting access to a specific, beneficial optional rule that generally isn’t used in the campaign, it gives an exemption from a particular, detrimental optional rule that is used in the campaign. For instance, Rules Exemption (Maintaining Skills) would allow a PC with high skill levels to keep them without practice in a campaign that uses Maintaining Skills (p. B294).

　As with Extra Option, exemptions that apply in cinematic or supernatural situations should have narrow specialties. For instance, if the GM requires material components for spells in his campaign, the ability to ignore them is a distinct perk for each spell.
For examples of exemptions from the standard rules, see No Nuisance Rolls (p. 16) and Standard Operating Procedure (p. 15).

　This works much like Extra Option (p. 24), except that instead of granting access to a specific, beneficial optional rule that isn’t used campaign-wide, it extends an exemption from a particular, detrimental optional rule that does apply to everybody else.
As with Extra Option, perks that facilitate ordinary, “tactical” casting require specialization by spell, while those that aid processes that are costly in terms of money, time, or personal health affect all spells – or at least all spells of a style.

　Examples:

　If the GM uses The Unarmored Wizard (Thaumatology, p. 28) to give spellcasters penalties while wearing armor, the ability ignore these penalties for one specific spell is a Magic Perk.

　If the GM uses Fearsome Magic (Thaumatology, p. 32) to make learning magic scary, an exemption for all spells of a style is a single perk. If he requires a Fright Check when casting,bypassing this calls for a separate Magic Perk per spell.

　If the GM uses Magic Ingredients (Magic, p. 8) for all spells, then the ability to cast a particular spell without any ingredients at all is a Magic Perk.

　Many examples of exemptions from standard (not optional) rules are already Magic Perks; e.g., Area Spell Mastery (p. 22), Blocking Spell Mastery (p. 23), Continuous Ritual (p. 23), Melee Spell Mastery (p. 27), Missile Spell Mastery (p. 28), No Gestures (p. 28), and No Incantations (p. 28). In all cases, remember that it’s never worth a perk to be exempt from a rule that the GM doesn’t use in the first place!
