Monsters who share their spawn with a Lottery Spawn monster are referred to as "placeholders". Killing a placeholder frees up the spawn point, allowing the lottery to "roll again" to determine which monster will spawn. This is the critical difference between lottery spawns and other spawns: if the placeholder for a lottery spawn monster is never killed, then the monster will never appear. Placeholders are usually, but not always, in the same as the monster. Many notorious monsters have 1 placeholder, though some, like Leaping Lizzy may have 2 or more. Placeholders may be immune to charm effects to stop Beastmasters from delaying respawns.
