Baseado nas regras para efeitos de encantamento sobrepostos , (ênfase adicionada)
Sometimes magical effects that establish mental control render each other irrelevant, such as spells that remove the subject’s ability to act. Mental controls that don’t remove the recipient’s ability to act usually do not interfere with each other. If a creature is under the mental control of two or more creatures, it tends to obey each to the best of its ability, and to the extent of the control each effect allows. If the controlled creature receives conflicting orders simultaneously, the competing controllers must make opposed Charisma checks to determine which one the creature obeys.
