How do I craft and use a tek helmet for underwater vision in ARK: Survival Evolved?

To craft and use a Tek Helmet for underwater vision in ARK: Survival Evolved, you need to follow a series of steps that involve resource gathering, crafting, and understanding the game's advanced technology mechanics. The Tek Helmet is part of the Tek Tier, which is the endgame technology in ARK, offering powerful tools and armor. The Tek Helmet, in particular, provides enhanced vision modes, including underwater vision, which is invaluable for exploring the ocean depths safely.

First, you need to unlock the Tek Helmet engram. This is done by defeating certain bosses in the game, such as the Broodmother, Megapithecus, or Dragon. Each boss drops specific Tekgrams, and the Tek Helmet engram is unlocked by defeating the Dragon. Once you have the engram, you can craft the Tek Helmet at a Tek Replicator, which is a high-tech crafting station that requires Element to operate.

To craft the Tek Helmet, you will need the following resources: 250 Metal Ingots, 75 Crystal, 50 Polymer, 50 Cementing Paste, and 20 Element. Metal Ingots are obtained by smelting Metal Ore in a Forge or Industrial Forge. Crystal can be mined from crystal nodes found in caves or mountains. Polymer can be harvested from killing Kairuku (penguins) or by crafting it from Obsidian and Cementing Paste in a Fabricator. Cementing Paste is made from Chitin/Keratin and Stone in a Mortar and Pestle or by harvesting it from Beavers or using a Cementing Paste farm with Achatina snails. Element is a rare resource obtained by defeating bosses or by crafting it in a Tek Replicator using Element Shards, which are found in the Genesis and Extinction maps.

Once you have gathered all the necessary resources, place them in the Tek Replicator and craft the Tek Helmet. The Tek Replicator requires Element to function, so ensure you have enough Element to power it. After crafting, equip the Tek Helmet in your armor slot.

To use the Tek Helmet's underwater vision, you need to activate its special vision mode. Press the designated key (default is H on PC) to cycle through the helmet's vision modes until you reach the underwater vision mode. This mode enhances your visibility underwater, making it easier to navigate and spot resources or threats. The Tek Helmet also provides oxygen, so you can stay underwater longer without needing to surface for air.

Important tips and considerations include ensuring you have a reliable source of Element, as the Tek Helmet consumes Element for its functions. Always carry extra Element in your inventory to keep the helmet powered. Additionally, the Tek Helmet is fragile and can break if it takes too much damage, so avoid engaging in combat with it unless necessary.

Common mistakes to avoid include not having enough Element to power the Tek Replicator or the helmet itself. Another mistake is not preparing adequately for boss fights to unlock the Tekgrams. Ensure you have strong tames, good armor, and plenty of supplies before attempting to defeat the Dragon or other bosses.

Advanced techniques involve using the Tek Helmet in combination with other Tek items, such as the Tek Suit, which provides additional protection and mobility. The Tek Suit's jetpack can be particularly useful for quickly navigating underwater environments. Additionally, using a high-level Basilosaurus or Tusoteuthis as a mount can complement the Tek Helmet's underwater capabilities, providing both transportation and protection.

Resource requirements and preparation are crucial. Stockpile Metal Ingots, Crystal, Polymer, and Cementing Paste well in advance. Establish a reliable source of Element, either through boss fights or by farming Element Shards. Consider setting up a dedicated crafting area with multiple Forges, Fabricators, and a Tek Replicator to streamline the crafting process.

Tribe and solo considerations differ slightly. In a tribe, you can divide the resource gathering and crafting tasks among members, making the process faster and more efficient. Solo players need to manage all aspects themselves, so planning and preparation are even more critical. Ensure you have a secure base with defenses to protect your valuable resources and crafting stations.

Specific examples and scenarios include using the Tek Helmet to explore underwater caves, such as the Caverns of Lost Hope or the Deep Sea Loot Crates. These areas are rich in resources but are also dangerous, with threats like Electrophorus and Cnidaria. The Tek Helmet's enhanced vision and oxygen supply make these expeditions safer and more productive.

In summary, crafting and using a Tek Helmet for underwater vision in ARK: Survival Evolved involves unlocking the engram through boss fights, gathering and preparing the necessary resources, crafting the helmet in a Tek Replicator, and utilizing its special vision mode. Proper preparation, resource management, and understanding of the game's mechanics are key to successfully using this advanced technology to enhance your underwater exploration and survival.
