Charm Person or Mammal

This spell will affect any single person or mammal it is cast upon. The creature then will regard the druid who cast the spell as a trusted friend and ally to be heeded and protected. 

The spell does not enable the druid to control the charmed creature as if it were an automaton, but any word or action of the druid will be viewed in its most favorable way. 

Thus, a charmed creature would not obey a suicide command, but might believe the druid if assured that the only chance to save the druid's life is if the creature holds back an onrushing red dragon for "just a round or two". 

Note also that the spell does not empower the druid with linguistic capabilities beyond those he or she normally possesses. 

The duration of the spell is a function of the charmed creature's intelligence, and it is tied to the saving throw. The spell may be broken if a saving throw is made, and this saving throw is checked on a periodic basis according to the creature's intelligence:

If the druid harms, or attempts to harm, the charmed creature by some overt action, or if a dispel magic (q.v.) is successfully cast upon the charmed creature, the charm will be broken automatically. 

The spell affects all mammalian animals and persons. The term person includes all bipedal human and humanoid creatures of approximately man-size, or less than man-size, including those affected by the hold person spell (q.v.). If the recipient of the charm person/charm mammal spell makes its saving throw versus the spell, its effect is negated.

If at the same time this spell is cast the subject is struck by any spell, missile or weapon which inflicts damage, the creature will make its saving throw at +1 per point of damage sustained. Naturally, this assumes damage is inflicted by members of the spell caster's party.

Remember that a charmed creature's or person's priorities are changed as regards the spell-caster, but the charmed one's basic personality and alignment are not. The spell is not enslave person or mammal. A request that a charmee make itself defenseless or that he/she/it be required to give up a valued item or cast a valuable spell or use a charge on a valued item (especially against the charmee's former associates or allies) could allow an immediate saving throw to see if the charm is thrown off. In like manner, a charmed figure will not necessarily tell everything he/she/it knows or draw maps of entire areas. A charmed figure can refuse a request, if such refusal is in character and will not directly cause harm to the charmer. Also, a charm spell does not substantially alter the charmee's feelings toward the charmer's friends and allies. The charmed person or creature will not react well to the charmer's allies making suggestions like "Ask him this question..." The charmee is oriented toward friendship and acceptance of the charmer, but this does not mean that he/she/it will put up with verbal or physical abuse from the charmer's associates.
