Spells (3e)

This charm makes a humanoid of Medium-size or smaller regard the character as his trusted friend and ally. If the creature is currently being threatened or attacked by the character or the character's allies, however, he receives a +5 bonus on his saving throw.

The spell does not enable the character to control the charmed person as if he were an automaton, but he perceives the character's words and actions in the most favorable way. The character can try to give the subject orders, but the character must win an opposed Charisma check to convince him to do anything he wouldn’t ordinarily do. (Retries not allowed.) A charmed person never obeys suicidal or obviously harmful orders. Any act by the character or the character's apparent allies that threatens the charmed person breaks the spell. Note also that the character must speak the person’s language to communicate the character's commands, or else be good at pantomiming.
