  • Antimagic Susceptibility. The knife familiar is incapacitated while in the area of an antimagic field. If targeted by dispel magic, the knife familiar must succeed on a Constitution saving throw against the caster’s spell save DC or fall unconscious for 1 minute.
  • False Appearance. While the knife familiar remains motionless and isn’t flying, it is indistinguishable from a normal knife.
  • Telepathy. A knife familiar can speak telepathically to its master and tell them everything it has seen or done within roughly a one-week period. Its memory is fleeting, and it can’t remember events more than a week ago.
