Fallout: The Traveler/Visions

A Vision is a technology built by West-Tek and the Enclave after the Great War and improved upon by the Board that only bestowed upon those who dwell in Halcyon and is only known within that region. It grants the user elemental abilities based on the element of their given Vision. Wielders of Visions are called allogenes, though this is not a widely known term.

Visions take the form of glowing gems, it's power source, encased by a decorative design, controlled by a glove that was connected through a universal port in the user’s hand. The power supply to the glove itself is delivered via thin monomolecular superconducting polymer rods, which are planted inside the marrow and the non-dominant arm. Allogenes carry their Visions on their person, whether attached to the glove or somewhere else on their person.

In the upper left corner of the character screen, there is an icon that represents a Companions Vision, with their element denoted by the gem and their in-game major faction denoted by the decorative design around the gem, even for the characters that do not use Visions and characters with non-standard Vision designs.

Abilities
To use a Vision ability, you must first select it from your list of available Visions in the Paimon-Pip/Pip-Boy and assign it to either your left or right vision slot in the equipment. Some Visions will trigger immediately upon being activated and can be maintained as long as held. Others require holding to charge the visions and releasing to cast it. Casting an ability of either form will initiate a cooldown period, varying between each Elemental Skill depletes the Traveler's AP based on the cost of the visions and will continue to do so if the visions is maintained.

The effects of a successfully activated Vision will usually be aimed in whatever direction the user is pointing or will simply become active on the user, depending on the nature of the particular Vision. Visions that don't target the one using them vary in range: some only work on touch, several are fired as projectiles, some are maintained as a short-ranged spray, and a few (primarily Rank V visions) affect everything within a certain distance of the user. Holographic and Burst Visions in particular also have a maximum activation range, meaning that if you attempt to aim the charged vision too far away from you, the vision will fail upon being released.

Visionpsychosis
Visionpsychosis is a mental illness, specifically a dissociative disorder, caused by an improper and overusing of Visions to the user.

Trivia

 * The appearance of the Vision in Fallout lore are based off the Polymer Glove from Atomic Heart rather than gemstones in Genshin Impact, though the gemstones still exist but changed to its power source.
 * The Visionpsychosis is based off the Cyberpsychosis in Cyberpunk 2077
