The second function of the protection from evil spell blocks any attempt to possess the warded creature or to exercise mental control over the creature. What, exactly, counts as mental control?
“Mental control” includes all spells of the school of Enchantment that have the Charm subschool, such as animal friendship, charm person, and charm monster. It also includes some Enchantment spells of the Compulsion subschool if those spells grant the caster ongoing control over the subject; such spells include dominate person and dominate monster.
Compulsions that merely dictate the subject’s action at the time the spell takes effect are not blocked. Such spells include command, hold person, geas/quest, hypnotism, insanity, Otto’s irresistible dance, random action, suggestion, and zone of truth.
