- The illusions always spawn in cardinal directions around the hero, starting on east and going counterclockwise.
- The hero's and the illusion's locations are not shuffled.
- The illusions spawn 108 range away from the hero if the hero has a collision size of 24, and 72 if the collision size is 8.
- Each illusion appears either north, east, south or west from the hero and face the same direction as the hero does.
- Activating a new Illusion Rune while already having illusions from a previous Illusion Rune does not replace them.
