How do I find and harvest rare resources like green gems in the Valguero map of ARK: Survival Evolved?

Finding and harvesting rare resources like green gems in the Valguero map of ARK: Survival Evolved requires a combination of exploration, preparation, and strategy. Green gems are a unique resource found primarily in the Aberration Trench and the Aberration Cave, two areas on the Valguero map that mimic the environment of the Aberration DLC. These gems are essential for crafting advanced items like the Tek Replicator, Tek Generator, and other Tek-tier equipment. Below is a detailed guide on how to locate and harvest green gems effectively.

First, you need to understand the mechanics of green gem harvesting. Green gems are found in clusters on the walls of the Aberration Trench and Aberration Cave. These clusters can be harvested using a pickaxe, a metal hatchet, or a creature with high melee damage like a Metal Pick Ankylosaurus. The yield of green gems depends on the tool or creature used, with higher melee damage generally resulting in more resources. Additionally, green gems are often found alongside other rare resources like blue gems and red gems, making these areas highly valuable for resource gathering.

To begin your journey, you need to prepare adequately. The Aberration Trench and Aberration Cave are dangerous areas filled with hostile creatures like Ravagers, Karkinos, and Nameless. It is crucial to bring a strong mount for protection and transportation. A high-level Rock Drake or a Megalosaurus is highly recommended due to their ability to navigate the challenging terrain and fight off enemies. You should also equip yourself with a good set of armor, weapons, and medical supplies to handle any threats. A crossbow with grappling hooks can be useful for navigating the vertical sections of the trench.

The Aberration Trench is located in the southwestern part of the Valguero map, near the coordinates 20 LAT, 60 LON. The entrance is a large, glowing crack in the ground that leads down into a series of tunnels and caverns. The Aberration Cave is another location where green gems can be found, and it is situated near the coordinates 50 LAT, 50 LON. Both areas are marked by their bioluminescent flora and fauna, making them easy to identify.

Once you reach the Aberration Trench or Cave, you need to locate the green gem clusters. These clusters are typically found on the walls and ceilings of the caverns. Use your mount or grappling hooks to reach these high areas. If you are using a pickaxe or hatchet, aim for the clusters and start harvesting. If you are using a creature like the Ankylosaurus, position it near the cluster and use its attack command to harvest the gems. Be mindful of your surroundings, as enemies can attack you while you are harvesting.

There are several important tips and considerations to keep in mind. First, always bring a light source, as the Aberration Trench and Cave are dark and difficult to navigate without one. A glow pet like a Bulbdog or a Lantern can be very helpful. Second, be aware of the Nameless, which spawn when you are in the area for too long without a light source. These creatures can quickly overwhelm you if you are not prepared. Third, consider bringing a Cryopod to store your mount if you need to navigate tight spaces or escape quickly.

Common mistakes to avoid include venturing into the Aberration Trench or Cave without proper preparation. Many players underestimate the dangers of these areas and end up losing their gear and mounts. Another mistake is not bringing enough resources to sustain yourself during the expedition. Always bring extra food, water, and medical supplies to ensure your survival.

Advanced techniques and optimizations can significantly improve your efficiency. For example, using a high-level Ankylosaurus with a high melee damage stat can yield more green gems per cluster. Additionally, setting up a small outpost near the entrance of the Aberration Trench or Cave can serve as a respawn point and storage area for your resources. This outpost should be well-defended to protect against enemy attacks.

Resource requirements and preparation are crucial for a successful expedition. You will need a strong mount, a good set of tools or a harvesting creature, armor, weapons, medical supplies, and a light source. It is also advisable to bring a Cryopod and some building materials to set up a temporary outpost.

Tribe and solo considerations differ slightly. In a tribe, you can divide tasks among members, with some focusing on harvesting while others provide protection. Solo players need to be more self-sufficient and cautious, as they do not have the backup of tribe members. In both cases, communication and coordination are key to success.

Specific examples and scenarios can help illustrate the process. For instance, a tribe might send a team of three players into the Aberration Trench, with one player riding a Rock Drake for mobility, another using an Ankylosaurus for harvesting, and the third providing support with a crossbow and medical supplies. They would set up a small outpost near the entrance to store their resources and respawn if necessary. A solo player, on the other hand, might use a Megalosaurus for both mobility and harvesting, relying on its night vision to navigate the dark caverns and its combat abilities to fend off enemies.

In conclusion, finding and harvesting green gems in the Valguero map requires careful preparation, strategic planning, and effective execution. By following the steps outlined above, you can successfully gather this valuable resource and advance your progress in ARK: Survival Evolved.
