Harvest Wisps are small mythical creatures in Harvest Moon: The Winds of Anthos that can be found floating aimlessly around the world or hiding in grass, rocks, and trees - only to be revealed once the item is destroyed. After finding and talking to one, the player will receive crop or flower seeds from the Wisp depending on their location. If the player's item bag is full, they will instead drop the seeds on the ground. These seeds can be collected anytime that day. On certain seasons that match the seeds, Wisps will give more seeds to the player. Once you complete the main story, the night time of the 8th and 22nd each month are Harvest Moon events. On these nights, multiple wisps would appear and give more seeds to the player.
There are three separate types of wisps that the player is able to find, defined by the clothing that they will wear.
Red Harvest Wisps are the most common wisp that spawns in Anthos. They will aimlessly float around in place until the player takes the seeds from them. They will give 1-2 seeds at a time. Up to 4 can show up during Harvest Moon nights.
Blue Harvest Wisps are much rarer. They are shy and will become alert as they are approached, eventually running away from the player and disappearing if they are approached without the player crouching. They give 3-5 seeds at a time. On Harvest Moon nights, they can give up to 10 seeds if they are in a secluded location usually barred by water passage. Also, they won't run from player on these nights.
Yellow Harvest Wisps are powerful Harvest Wisps and give the player a power fruit. Three power fruits can be exchanged at the Harvest Goddess Spring, for either a three-slot bag upgrade to each individual bag or one extra stamina heart. Their location will be marked on the map with a yellow acorn, and they will not respawn here once found. There are 160 Power Wisps in WOA.
There are a total of 160 power wisps that can be found in Anthos. They can be found free floating or hiding in rocks and trees. Below is a map of all their locations and the requirements to obtain them.
