别想多了，中立牧师要先选引导正能量还是负能量，要是选了正能量你连这个法术都放不出来，要是选了负能量你根本不需要理由
Chaotic, Evil, Good, and Lawful Spells: A cleric can’t cast spells
of an alignment opposed to his own or his deity’s (if he has one). For
example, a good cleric (or a neutral cleric of a good deity) cannot cast
evil spells. Spells associated with particular alignments are indicated
by the chaos, evil, good, and law descriptors in their spell
descriptions (see Chapter 11: Spells).
Turn or Rebuke Undead (Su): Any cleric, regardless of alignment,
has the power to affect undead creatures (such as skeletons,
zombies, ghosts, and vampires) by channeling the power of his faith
through his holy (or unholy) symbol (see Turn or Rebuke Undead,
page 159).
A good cleric (or a neutral cleric who worships a good deity) can
turn or destroy undead creatures. An evil cleric (or a neutral cleric
who worships an evil deity) instead rebukes or commands such
creatures., forcing them to cower in awe of his power. If your
character is a neutral cleric of a neutral deity, you must choose
whether his turning ability functions as that of a good cleric or an
evil cleric. Once you make this choice, it cannot be reversed. This
decision also determines whether the cleric can cast spontaneous
cure or inflict spells (see above). Exceptions: All lawful neutral clerics of
Wee Jas (goddess of death and magic) rebuke or command undead.
All clerics of St. Cuthbert (god of retribution) and all nonevil clerics
of Obad-Hai (god of nature) turn of destroy undead.
A cleric may attempt to turn undead a number of times per day
equal to 3 + his Charisma modifier. A cleric with 5 or more ranks in
Knowledge (religion) gets a +2 bonus on turning checks against
undead.
没这个说法吧。只要在一条阵营轴上牧师本身和其神祇都是中立的，他施法就不受该阵营轴限制。
