Eight eidolons, who wear the standard red hooded cloak, are found within specific locations in the three world maps: Overworld, Underworld, and the Red Moon. They can be found in towns, caves, mountains, and other specific places. If spoken to, the eidolon will provide a clue, and the clue will switch to the next when the player fetches the friend he mentioned. The eidolons fetched will be seen gathered in the house to help the player keep track of the number. If the player returns to the house with all eight eidolons, he will be rewarded with the Piercing Magic augment.
