The Charm Person spell affects any single humanoid creature it is cast upon. Giants and other large bipedal creatures are not affected.
|“|| This spell affects any single person it is cast upon. The term person includes any bipedal human, demihuman, or humanoid of man-size or smaller, such as brownies, dryads, dwarves, elves, gnolls, gnomes, goblins, half-elves, halflings, half-orcs, hobgoblins, humans, kobolds, lizard men, nixies, orcs, pixies, sprites, troglodytes, and others. Thus, a 10th-level fighter could be charmed, but an ogre could not. The person is allowed a Saving Throw vs. Spell to negate the effect.|
If the spell's recipient fails his Saving Throw (with a +3 modifier), he regards the caster as a trusted friend and ally to be heeded and protected. The caster may give him orders, and the charmed individual will carry them out as quickly as possible.
If the caster harms—or attempts to harm—the charmed person by some overt action, or if a Dispel Magic spell is cast upon the charmed person, the Charm spell is broken. If two or more Charms simultaneously affect a creature, the most recent Charm takes precedence. A formerly charmed subject is fully aware of what occurred while he was under the spell's influence. Note that a charmed creature cannot leave the area where he is charmed.
