Weavers are able to reanimate the husks of humans who have been killed, turning the husks into Phantoms. While humans killed by Mimics are typically selected for this, any body can suffice, as evidenced in Cargo Bay when one makes a Phantom from Enoch Kouneva while Alfred Rose and Sam Hertz look on in distaste.
They can create Typhon creatures like the Telepath in order to protect the Typhon ecology and reach their goals. If attacked, the Weavers can manifest or bring about Cystoids to protect itself. It is unknown if the mass to create these defences come from the Weaver itself or from some other source.
Weavers get their name from their production of Coral, a luminescent web-like substance that hangs in the air wherever Weavers have been active for some time.
However, on some occasions their attempt to create a Phantom fails, resulting to the elusive Poltergeist as a result.
Weavers are actually a Mimic that have been stung repeatedly by a group of other Mimics, transforming the Mimic into the Weaver. It seems to have the ability to "promote" average Mimics to the greater/elite variant, which do more damage, are much faster, and harder to kill and can be a nuisance. Weavers look like clustered tentacles, 3 in the top and several on the underside. Abilities are stated above, but not limited to Typhonisation (converting normal matter to Typhon material) of husks, upgrade Mimics it sees fit, and produces Coral, which color is shining gold.
A Weaver's golden shield appears to mitigate all, if not most damage dealt against it on a first hit. Afterward, the shield will be broken for only short window, during which a Weaver will attempt to flee, floating away from the player and even capable of some short range teleportation. Coupled with its Backlash ability which will throw the player's camera control off kilter and the myriad of Cystoids a Weaver is capable of spawning it, makes them an extremely difficult opponent to pin down.
If the Player has the Fear Shielding Scope Chipset activated however, they will be shielded from the Fear effect applied when its Backlash ability is triggered. As a result, this makes the Weavers incredibly trivial to deal with, as they do not have a lot of health once their shield is down. Several shots with a pistol can usually wipe them out. If Fear Shielding is not available to be added, drinking any type of alcohol will remove the fear effect as well, at the cost of stumbling and blurry vision, unless the Psychoactive Amp Suit Chipset is installed, which disables the negative effects of alcohol while still letting it negate fear as well as give bonus melee damage. As such, it's a good idea to keep a couple bottles in your inventory for these cases.
Weavers are capable of making Phantoms from bodies at any time. As a precaution, move any bodies you can in advance, get them out of the way to reduce the chance of it creating backup. If you see a Weaver in the process of making a Phantom from a body, you can shoot at the Weaver. Even if you don't hit it directly, hitting a point close enough to it will get its attention and make it drop the body again. Although you lose the element of surprise, it means the Weaver won't have an extra Phantom supporting it.
Melee appears to be an extremely ineffectual strategy without the aid of a psychic inhibitor such as Psychoshock or a Nullwave. The Weaver's shield, if the player can even manage to approach them unnoticed and uninhibited by Cystoids, will nullify any first hit against them making sneak attacks incredibly difficult to pull off. This leaves them vulnerable only in the brief period following, during which the player will still have to deal with the Cystoids it spawns and hope the weaver doesn't simply float out of range, which it is quite capable of doing.
The Q-beam appears to be highly effective against them, its lack of direct damage won't rupture the Weaver's shield and cause it to deal Backlash, which will also prompt it to remain and fight rather than to flee and teleport away, making it a far easier target. Just be careful with the plethora of Cystoids that the Weaver spawns, making it best engaged from a distance and ideally at a high vantage point. Recommended to start Q-beam on the Weaver right before the player is spotted. Watch out for its Backlash ability. It's best to nullify it then kill it.
