Etymology

"Cave inimicum" is a Latin phrase meaning "beware of the enemy".

Behind the scenes

  • Given the etymology, this spell appears to warn of approaching enemies, similar to the Caterwauling Charm or Intruder Charm.
  • This spell may be similar to Repello Inimicum due to both spells sharing similar etymology, though Repello Inimicum is used to repel enemies instead of warning the caster of them, which this spell is presumed to do.
