I have used the Chalice (admittedly while abusing Tartarian Gate), can't remember ever seeing an attack from that. Horror attacks, however, are a different matter. I suspect that some items not only horror mark you (making it more likely that a horror or Ashen Angel will preferentially attack you) but also increase the chance of a horror arriving at all. The Gift of Kurgi might be one of these, and the Forbidden Light almost certainly is. OTOH, Mage Bane, which does horror mark you, doesn't seem to attract 'em in droves by itself.
