 + * WARNING: This event only fires for a limited number of cases, and not for every case that CreatureSpawnEvent does.
 + *
 + * You should still listen to CreatureSpawnEvent as a backup, and only use this event as an "enhancement".
-+ * The intent of this event is to improve server performance, so limited use cases.
++ * The intent of this event is to improve server performance, so it fires even if the spawning might fail later, for
++ * example when the entity would be unable to spawn due to limited space or lighting.
 + * 
 + * Currently: NATURAL and SPAWNER based reasons. Please submit a Pull Request for future additions.
 + * Also, Plugins that replace Entity Registrations with their own custom entities might not fire this event.
