Charmed

Charmed is a status effect in all games of the Baldur's Gate series.

It can be caused by spells like Charm Person and Charm Person or Mammal. Some races, e.g. elves, have resistances against the effect, and some creatures are completely immune to it. A charmed being will not take hostile action anymore against the person or creature it was charmed by and their affiliates.

Charming others
A number of persons in the games have unique dialogue options if being charmed, and may this way reveal information – even journal entries –, Gorion's Ward would have gathered not at all otherwise or only on more complicated paths. Sometimes, however, it's … surprising.
