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: Intelligence Score Period Between Chocks 3 or less 3 months 4to6 2 months 7109 1 month 10 to 12 3 weeks 13 to 14 2 weeks 15 to 16 1 week 17 3 days 18 2 days 19 or more 1 day 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 or mammal spell makes its saving throw versus the spell, its effect is negated.
