Rubber

You can collect Rubber as early as Chapter IX, as the only requirement is to have access to the Crimson Desert area of the Map.

Where to find the Rubber Trees

You’ll need to head to the southern rainforests of the Crimson Desert. Its stretch of rainforest that holds just a handful of Rubber Trees. Below is what the trees look like and where to find one, though there are multiple nearby.

Basic method of extracting Rubber

To collect Rubber you’ll need to find these trees and heal up their leaks using Healing Force Palm. This will leave a glowing mark behind, indicating that the rubber is forming. This will need to be repeated multiple times over multiple in-game days before collecting any Rubber.

Collecting Rubber with Magic Scythe

You can invest in getting the Magic Scythe from the hidden town of Pororin. This will require a hefty sum of 630,000 camp funds to research, including the previous research before it.

This allows you to dispatch a Mission from your camp to craft a Magic Scythe. This powerful tool allows you to quickly harvest Rubber from a Rubber Tree, without the need to repeatedly tend to it with Healing Force Palm.

Collecting Rubber with Kuku Gardening Pack

The most sophisticated and by far the easiest and quickest method is to use the Kuku Gardening Pack. By pressing just one button while next to a Rubber Tree, the Pack will automatically extract and collect all of the Rubber immediately.

Get Rubber as gifts

If you max out trust with random Scholars (easily found around the Scholastone Institute), they can give you Rubber as a gift.
