1 cursed technique and domain

Innate Cursed Technique:

Thread-Spinning Technique - The user can manipulate their cursed energy to create threads they can freely control. These threads are nearly imperceptible, however they can be seen if they catch light. Their energy can also be sensed, although it typically isn't strong enough to draw unwarranted attention. Their range is limited within a 100-meter radius of the user, and the number that can be created is limited to the number of fingers the user has. Normally that's ten, but someone like Sukuna, with four arms, could use twenty. The standard offensive usage for this technique is to use them like whips, as they're razor-sharp and will leave lacerations. The stronger the user, the deeper they'll cut. If the user so wished, they could also "pull their punches" so to speak and thicken the threads to make them more blunt and less lethal. These will leave nasty welts and bruises, but won't otherwise harm the target.

Extension Techniques:

Control - The user can anchor their threads to anything and manipulate it like a puppet. This technique requires tremendous concentration, as it is essentially exerting one's will over that of another's. It works better on inanimate objects that resemble living things, like mannequins or dolls. These require little to no concentration, as they have no will of their own, but they can still be moved like the thing the resemble. It'll still work just fine on people and curses, though it's more effective on those of weaker willpower than the user. "Control" can also be forcefully dispelled if someone, either the target themselves or a third party, manages to break the threads or their connection to the target. The effectiveness increases with the user's power and the strength of their own willpower.

Bind - The user's threads can be reinforced with more cursed energy to restrain an individual for a time, and they will tighten around the target like a boa constrictor. The duration depends on how much cursed energy was used to bolster the threads, as this technique actively burns through it the moment it's activated. It's most useful at the beginning of battle, when the user has the most cursed energy. It is, however, unwise to pour all of one's power into this technique. Powerful cursed spirits and people can manage break out just fine. Though, the more threads that are used to bind an individual, the harder it is to do that. Blunt threads are normally used to make this technique non-lethal, however thin ones could also be used to slice the user's target like minced meat as the threads coil tighter around them. Curses will be exorcised and disappear once the threads cut far enough into them, unless they have a human vessel like the Cursed Wombs: Death Paintings. While a target is bound, the user could toss them around like the Hulk did to Loki and Thor. Of course, this does require them to be physically strong enough to even be able do that in the first place.

Tripwire - The user can anchor their threads to two separate points per each one to create a trap for their target. It can be used to create a standard tripwire, or for something more elaborate. A trap could even be created around the target without their notice if the user is careful enough, and it can render them immobile if they don't want to get hurt. Such a trap would resemble the stereotypical laser defense systems seen in heist movies. Only, hitting a thread wouldn't set off an alarm. It would just leave you with a cut, the severity of which would depend on how hard you hit it. Breaking the threads in this technique will cause them to snap like rubber bands and hit you anyway, so doing that is ill-advised if you're adverse to pain. It'll hurt like a bitch for sure, but it won't kill you. The best use for this technique is to flee from battle, as it isn't particularly strong. At best, it serves as a momentary delay to hinder the user's opponent. But a moment may be all they need to escape a stronger adversary.

Grapple - If the user ever dreamed of being Spider-Man, this is that wish fulfilled. They can sling threads to improve mobility by anchoring one end to their target surface. It's particularly useful in urban environments or wooded areas with tall trees, for obvious reasons. It's kinda hard to swing around from things that are close to the ground, after all. This technique could also be used like a grappling hook to simply scale tall skyscrapers, cliff faces, and the like if the user lacks the momentum to simply swing to the top. Either way is not any more or less effective than the other. If the user wanted to, they could also anchor their threads to a living thing to pull it closer without controlling it like a puppet. That could be handy if you wanted to pull someone off of somewhere high up, like a balcony.

Anchoring - Attaching a thread to something involves the end of a thread stabbing into the target, and the user sending their cursed energy through it to keep the other end stuck inside the target. It could be ripped out, but a chunk of whatever the thread is anchored to will probably come off with it. If the target happens to be a person, it would be wiser for them to find a way to cut through the thread, or to get the user to release them. Could you imagine getting not only one, but ten chunks of flesh getting torn from your body? Ouch.

Domain Expansion:

Tangled Web of the Weaver - This will affect anything within its effective range, and the Domain takes the form of a giant spider's web. The range varies depending on the strength of the user, but it cannot ever exceed 150 meters regardless. The user could choose a smaller range if they so wished, to keep from trapping innocents. The surroundings of the Tangled Web itself are very dark, making it hard to see where attacks are coming from. Not that it matters; everything caught in the web is trapped like a fly, and any attack made against them is guaranteed to hit. It is exceedingly difficult to break free from the web, however a powerful enough individual could manage it. This may allow them more mobility, but it doesn't exempt them from the guaranteed hits. The Domain itself is impossible to escape from within anyway, even if you manage to break free of the Web. Your only hope is to expand your own Domain or have an ally break in to rescue you. While the Tangled Web of the Weaver is in effect, the user is also granted temporary access to a shikigami of sorts in the form of a giant spider. It cannot be summoned outside the Domain, This spider, called the Weaver, can be used to cocoon anything that has been trapped in the Tangled Web. Once something is cocooned, it will bite it to inject it with a non-toxic venom meant to render it unconscious. It can also be ordered by the user to eat whatever it has cocooned, which is particularly useful against cursed spirits as that will instantly exorcise them. It would obviously kill any person it eats as well lol.
