A ver si es un hechizo nuevo de 7ª edición (¿los hay?)
Yo también voto por "Palabras de poder".
EDITO: Sí, es un hechizo que viene en el manual del Guardian de 7ª Edición, concretamente en la página 265. Pongo el texto:
Words of PowerCost: 3+ magic points; 1D6 Sanity points
Casting time: 10+ minutes
The caster creates an intense bond with a large group of listeners. The caster must speak extemporaneously and seemingly from the heart, maintaining the audience’s attention. For each ten minutes of speech, the caster must expend 3 magic points and make a successful communication roll as the Keeper thinks appropriate (Charm or Persuade), or the speech ends indecisively and in confusion. At the end of a successful speech, the audience thoroughly believes what has been said for 1D3 days.
Alternative names: Sekhmenkenhep’s Words, Beguile the Unrighteous, Mastery of the Mob.
