I gather that the Glowspot created by the Crimson Bat allows Lunar Magicians to cast magic as though the Red Moon were in it’s Full Phase, while the Glowline only allows them to cast magic as though it were in it’s Half Phase? I’m supposing here that the comment in the RuneQuest Bestiary “The Bat exerts a force which acts in all ways as the Lunar Glowline for Lunar magicians. All Lunar magicians within the Glowspot of the Bat act as if the Red Moon is Full” is a reflection of it’s description from RQ2/3.
