In this guide, you will learn how to obtain two specific soils in AI Limit: the Twilight Hill Soil and the Arboretum Soil. The process involves opening and accessing a particular area.

If you have already reached Twilight Hill and Arboretum locations, it will be straightforward from these points onward. However, if you haven't, follow the steps below to get started.

Begin your journey by teleporting to the Twilight Hill Dormant Array. This is the starting point for finding the Twilight Hill Soil. As you progress, remember that some aspects of the game may differ slightly — for example, some eyes may be deactivated, and enemies might be absent.

From the teleportation point, cross the bridge ahead. Once you cross it, you will arrive at the Twilight Watchtower. Make sure you have the Missile Barrage spell equipped and enough damage to deal with any resistance. Proceed forward, keeping in mind that certain features like eyes may still be active for you. Focus on reaching the soil location directly.

You can hide to avoid confrontation, but your goal is to obtain the Twilight Hill Soil at this stage. Once you reach the designated area, pick up the soil.

Next, you'll proceed to find the Arboretum Soil. Head forward from your current location. You might encounter a large enemy robot or a battle between two enemies. Clear the area if necessary. Switch weapons if needed to handle stronger foes.

Look for an invisible bridge that you can identify from your vantage point. Cross it carefully and wait for it to appear clearly before stepping onto it. Once across, you'll find yourself at a location where you can activate some eyes. If you haven't done this yet, now is a good time.

Continue by activating a shortcut in the area. After that, make your way upward to the top. Expect to encounter a butterfly-type enemy here, which you can eliminate if this is your first playthrough. Ignore any additional hostile enemies that may not be essential to your objective.

Once you've ascended, go down to the next section, where you'll encounter an enemy on the left. Defeat it and activate the mechanism to open the stairs. Climb them to return to the Dormant Array — the location where you started.

Accessing the Arboretum Soil

To access the second soil, proceed onward from the Dormant Array. Engage in some light platforming by jumping across areas. Be prepared to eliminate any enemies in your path to ensure a clear route.

Continue moving forward until you reach a rift. Enter the rift and follow the path ahead. Eventually, you will come to a closed door. Beyond this door, on the floor, you'll find the Arboretum Soil — a purple item indicating the correct spot.
