AI Limit All Soil Sample Locations

AI Limit has a total of 7 Soil Samples to collect throughout the game. These are required to progress Delpha’s questline, which is related to two of the endings. Turning in the Soil Samples also causes Delpha to give you Purified Soil, which is used at the Branch to increase your maximum number of Life Dew charges.

None of the Soil Samples are missable, but Delpha himself will disappear from the game if you don’t complete his questline before speaking with Loskid after defeating her in the second last area of the game. This then locks you in to The End of Childhood ending and causes most NPCs to disappear from the game, rendering their sidequests unfinishable.

Collecting all Soil Samples is related to the following trophies/achievements:

• Boundless Stars – Accept the invitation of the Sphere Gods and step into the stars.
• Second Dawn – Decline the invitation of the Sphere Gods and explore the future with mankind.
• Blooming Life – Help Delpha grow plants and obtain the Azure Branch.
• Last Promise – Promise Shirley that you will build a new home with her.
• Gardener – Cultivate the Branch to the maximum level.
• Charon, the Nurturer – Defeat Charon, the Nurturer.

Soil Samples

Below are listed in the order they can be obtained as you progress through game.

Soil #1: Flooded Street

Branch: Sunken City Overground – Flooded Street > Survivors’ Stronghold

This soil is left of the branch beside the NPC looking at the wall.

Soil #2: Withered Forest

Branch: Twilight Hill – Withered Forest > Deadwoods

From the Branch go to the right into the large poison lake and take the middle path that turns to the left. Follow it to a cave where the soil is on the left (red circle below).

Soil #3: Underground Parish

Branch: Sunken City Underground – Underground Parish > Mansion Ground Floor

From the Branch, follow the main path until you reach the large room with the harpoon enemy on the upper right platform. Drop down the two long platforms in the middle of the room and into the pipe below. Turn to the blocked off end of the pipe to find the sample.

Soil #4: Sewer

Branch: Sewer Town – North > Sedimentation Tank

From the branch follow the main path and drop down to the lowest level where there is a large armored Void enemy in the area in front of the destroyed robot. The soil is behind it near the wall (green circle below).

Soil #5: Twilight Hill

Branch: Twilight Hill – Spirit Depths > Watch Tower

From the Branch follow the main path across the first red walkway, then left and drop down to the next level where there are three Church enemies. Go counterclockwise around the area to where there is a small side room. Pick this up in the corner.

Soil #6: Arboretum

Branch: Twilight Hill – Withered Forest > Arboretum

To find this soil you first need to reach the Arboretum hidden area. To do this, start from the Branch Twilight Hill – Spirit Depths > Watch Tower and follow the main path past the room where the Cleansing Knight and Panic Reaper minibosses are fighting when you go through the area the first time. Drop down to the next set of red platforms  and the one that is sticking slightly farther out has an invisible section leading toward the central tower.

Go into the central tower and take the elevator up to the next level. If this is your first time in here you can press the button to disable the sentry eyes, then drop a ladder back to the previous Branch. You can then take the elevator all the way to the top where there is a Church enemy and a Butterfly that drops a Dew Essence. Take the next elevator down, then look off the side to see red platforms below. Drop down to reach the lower area, then go right (left in below image, doorward ahead is the elevator shaft) to find a rift leading to the Arboretum hidden area.

In the Arboretum continue into the building and pick this up right before the Branch. Note after bringing Delpha this soil he will move inside the Arboretum instead of staying at the Temporary Campsite.

Soil #7: Subway Station

Branch: Sewer Town – Center > Subway Station

From the Branch continue on the main path until you drop into a hole with some poison-spitting human enemies around you, the soil is nearby just off the platform you drop onto.
