per amore della chiareza l'incanto è questo:
Charm Person
Enchantment (Charm) [Mind-Affecting]
Level: Brd 1, Sor/Wiz 1
Components: V, S
Casting Time: 1 standard action
Range: Close (25 ft. + 5 ft./2 levels)
Target: One humanoid creature
Duration: 1 hour/level
Saving Throw: Will negates
Spell Resistance: Yes
This charm makes a humanoid creature regard you as its trusted friend and ally (treat the target’s attitude as friendly). If the creature is currently being threatened or attacked by you or your allies, however, it receives a +5 bonus on its saving throw.
The spell does not enable you to control the charmed person as if it were an automaton, but it perceives your words and actions in the most favorable way. You can try to give the subject orders, but you must win an opposed Charisma check to convince it to do anything it wouldn’t ordinarily do. (Retries are not allowed.) An affected creature never obeys suicidal or obviously harmful orders, but it might be convinced that something very dangerous is worth doing. Any act by you or your apparent allies that threatens the charmed person breaks the spell. You must speak the person’s language to communicate your commands, or else be good at pantomiming.
ora se andiamo su diplomazia e guardiamo l'atteggiamento vediamo che:
riendly Wishes you well Chat, advise, offer limited help, advocate
adesso, andare ad attaccare 3 propri amici forti come te stesso in cui rischi la vita non mi sembra "offrire aiutolimitato"
aiuterebbe se il mind flyer venisse attaccato, ma attaccarlo IMHO no
