Regression meta think tank!

it's nearly impossible to have a build for high skill levels without any gen regression, but since MMR is so terrible that you will rarely bump up to some really high skill level squads, i would probably use 1-2 info perks combined with some utility and chase.

Quite possibly a kind of build:

Bamboozle-BBQ-Agi-Lethal

as i already mentioned, in pubs everything will work because MMR system is so bad that you will be guaranteed a team with at least one terrible player.

Additionally, if we talk about higher skill levels, i think NA survivors are much more convergent regarding ideas about usage of their perks, while EU ones are much more divergent.

yep, tho problem is, if you actually tried to play against EU survivors, the jump in ping would make it unbearable.

Don't go full regression tho, that's just bottlenecking your build, I myself tend to usually go Corrupt + 1 or 2 utility perk and 1-2 gen regression perks. For weaker killers, i would definitely suggest throwing one chase perk (preferably Bamboozle) in your build just because it will be your only way to reliably shorten chases against good survivors (you still need to use it very wisely to get it's value)

Technically, I know that people don't like when we talk about a streamer or whatever… But you can be interested by Lilith Omen, a Blight Main, he never kick a gen in all his match (and seem's to not use any regression perk in general, maybe some times ruin)

For myself… I love trying some "special" build, like Formula Haag
Give her the waterlogged shoes, and the scarred hand, with: batteries included, play with your food, remember me (a perk that I love) and some other perk (you can combine that with Noed, but I don't like this perk, game afoot or machine learning if you want to kick some gen)

And you got a Haag, who run at:

Batterie, Play with your food: max 137,5%
Batterie, Play with your food, Noed: max 142.5% at end game
Batterie, Play with your food, Game afoot: max 142.5%
Batterie, Play with your food, Machine learning: max 147.5% each time a corrupted gen is completed
Batterie, Play with your food, Machine learning and furtive chase: max at 152.5%

Imagine a tiny haag who burst into you without any terror radius
It's not really a powerfull build, but a funny build

CI, Pain Res, Bamboozle and BBQ, but I have been playing more Knight than Freddy these days.

I am tired of playing a killer with no power.

I've been alternating between an anti heal chucky build using leverage, plaything, penti, pain res with straight razor add on.

And furtive, machine learning, pain rez and rapid. But imo that works better on Vecna (still really scary to face if you get it to work though)

I normally play my half endgame half don't you dare healing build on Chucky. Noed, No way out, Leverage and scourge pain ress. I use the razor blade addon to get the sloppy butcher effect to make healing even more painful.

Hex: Devour Hope, Hex: Undying, No Way Out, and one of [Coup, Bamboozle, Mindbreaker, or Cruel Limits] on Wraith. Cloaked Move Speed and either Cloaked Break Speed or Uncloak Speed addons. I find even the extra few seconds survivors spend breaking the totems can buy enough time to get winning momentum.

STBFL/Rapid Brutality. Superior Anatomy/Unbound. Spirit Fury/Enduring. Coup De Grace. Batteries Included. Dissolution. You name it. They're not all great options, but they're something.

"High level" does not exist in BHVR's matchmaking. If you aren't playing scrims/tournaments against high-level players (which, if you are, none of this matters anyway), you can play killer perkless and add-onless and still win most if not all of your matches, many of them decisively, simply by being good enough at the game. This has been true and proven to be true time and again, for years. So yes, using regression/slowdown builds is indeed not the only viable way to play - if you get good enough/are a "high-level" player, much of anything is "viable".

…Now for the actual topic. Here's a handful (mostly) slowdown-free builds of many different ones I like to use at times and that I consider to be highly viable at most levels of play (I'll assume by "regression" you mean anything that slows the game down directly, i. e. including things like Corrupt Intervention and Dead Man's Switch or Pentimento):

Devour Hope + Undying + Haunted Ground + NOED - Devour Hope is really the star of this and many other builds of mine. It is a criminally underrated or certainly at least underused/undervalued perk that will turn any match in which it survives until it has 3 tokens on its head and regularly wins the game from there on out as survivors scramble trying to cleanse it in a chaotic frenzy, abandon the concept of repairing gens completely and hesitate or even refuse to unhook others. And even if they do manage to eventually get rid of it, the damage already done will often be so vast that there's no real coming back from, any hope they had left in shambles… It's a great perk design that encourages killers to and rewards them for venturing out and refraining from camping and tunnelling much, and can allow a killer to come back and win out even in the worst case of only having gotten 3 hook stages over the course of a match.

The other perks here are really only there to support Devour, keeping it alive longer, with Haunted acting as both a decoy, deterrent and a way to potentially get some fast and early downs that can escalate into a fast and early stacked-up Devour. Both Haunted and NOED are also hilarious with Devour, creating many comedic scenarios where survivors will, for instance, cleanse Haunted while Devour already has them Exposed, or have fought a hard battle through Devour, having finally managed to cleanse it, only to be hit by NOED. But both or either of these perks could also be replaced with a selection of Ruin, Blood Favor, Crowd Control or Pentimento. It's just that those tend to send the survivors out on totem patrol, whereas without any Hex in play that actually harms survivors (and with Haunted harming them only if cleansed of course), these perks make it more likely that survivors will simply miss, neglect or altogether ignore totems until it is too late. Thrill Of The Hunt and Dominance deserve mention for two more perks that can be used to fortify Devour. There's also a bunch of killers that are downright oppressive at playing around it, such as Singularity that can guard it with pods, Trapper that can lock it down with Bloody Coil and/or Iri Stone, Demo that can get notified if someone is around it and quickly traverse there from anywhere, Knight that can protect it with guards, Twins that can park either of the two there, as well as a whole bunch of ranged and mobility killers that have an easy time forcing survivors off their totem either from afar or by continually and quickly being able to return to it. Mirror Myers is also crazy with this.

In general I would recommend just trying Devour sometimes, you don't even have to build around it necessarily either, just throwing it randomly into an otherwise regular build of yours will work out sometimes and it can win games on its own and make a lot of matches much more exciting as you anticipate building up to that 3-token threshold, and enjoy watching the chaos unfold whenever you do.

Infectious Fright + Knock Out + Barbecue & Chilli + Anything You Want - Slugging is really fun, for both sides. As long as it's not the tired old "slugging for the 4k" in a foregone conclusion of a match or leaving people to bleed out on the ground for no reason other than to annoy them, slugging actually creates very engaging, chase-centric, low-downtime matches that are a constant back-and-forth and that even after 10 minutes of gameplay can still be entirely open for either side to come out victorious of. It feels just as great to recover from a precarious situation where 2-3 people had been slugged and the last person standing made a clutch play as it does to finally manage to get everyone after having gone through multiple cycles of almost having had gotten there. And since survivors don't accumulate hook stages, they will usually feel great if they get healed back up, truly "reset" and back up and running.

Of course, you can do this without a build dedicated to it altogether and just keep slugging, but for most killers/players this is not feasible if they actually want to also win sometimes. This is where Knock Out comes in, which can make this strategy that much more potent and slow the game down naturally as well as increase the likeliness to snowball slugging into a win. Barbecue is here because rather than simply slug all the time (which is something you can do, but which can be pretty boring for both the survivors and yourself as you are frequently left to randomly patrol gens and search for other survivors after that), we only slug if Infectious Fright procs. So if you down someone and get an Infectious scream, you leave them on the floor and go for the other survivor; if you don't get a scream, you hook the survivor and Barbecue will then lead you to your next targets instead. Not only does this gameplay flow yield a more dynamic match where you should most of the time be engaged in chasing, but it also actually builds more pressure to have survivors both slugged and hooked and to gradually build up hook stages on people. Obviously there are many situations where you can and will optimally want to deviate from this pattern to some degree, but as a basic play paradigm, trust me, it will get you far.

Knock Out obviously works best or should ideally only really be used on M1 killers, or at the very least killers that will regularly down people with M1s. I really like to use this build on Legion or Plague for instance. On M2 killers, you can either simply use Third Seal instead of KO, or just go with Fright + Barbecue alone. Some of the high-mobility killers really don't even need Knock Out/Seal to benefit from slugging, and can often in fact capitalize on survivors quickly rushing to pick up a slugged survivor rather than not finding them or not even trying to pick them due to not seeing them, as those killers can of course quickly return to the slug at much of any point, then finding multiple targets there to potentially down in quick succession. Try this on Nurse/Billy/Blight and if you're any good at them you'll get a lot of 4ks at 3+ gens remaining.

The last perk to round the build out can be much of anything, including of course slowdown perks such as Corrupt or Surge or Ruin or the like. But since this topic is about slowdown-free builds, I would recommend Sloppy Butcher or a chase perk such as Bamboozle or Save The Best For Last. Monitor & Abuse can also be really interesting in this build, as it not only increases your Infectious range to 40m (then really covering anything Barbecue wouldn't), but also makes it more likely to catch survivors scrambling to find slugs and reset with their pants down, adding to your potential to snowball. On M2 killers, using both Monitor and Nurse's Calling alongside Barbecue and Fright can be a really potent combo. On Nurse you can even go Monitor, Barbecue, Fright plus a perk of your choosing (Nowhere To Hide or Predator or something) and use Bad Man Keepsake (Nurse's Calling in add-on form) and Fragile Wheeze (Mangled add-on) instead.

Wherever you end up going with this, I encourage anyone to slug more (unless it's slugging the second-to-last remaining survivor for the 4k or merely to bleed people out). You will have success and a blast with this, and as will many of the survivors, even if they may not always appreciate it or even understand that they had a pretty fun round all things considered.

Blood Favour + Save The Best For Last + Dissolution + Enduring - This is a really cool and synergistic chase build that will often be downright oppressive to the survivors' ability to last long enough in chases. So the ideas here are the following: If you hit someone, active pallets get blocked by Favour, and since you have STBFL, they often won't make it far enough to get to unblocked pallets, or long enough for the pallets to become unblocked; pallets that are already dropped cannot be played because of Dissolution; if you hit someone around a dropped pallet with a stacked-up STBFL, they also won't regularly make it far, thus having to play the dropped pallet, which Dissolution again makes unplayable; if you hit someone through a pallet drop, the shortened stun thanks to Enduring also regularly renders survivors without the option to leave the tile, upon which Dissolution again screws them.

With this build you want to almost never break pallets, as left-up pallets are actually more so traps for survivors than they are beneficial to them. With STBFL being a centerpiece to most of its synergies, this build is obviously best-suited for M1 killers (Wraith, Pinhead and Clown being some of the killers that have a particularly good time making use of it), but you can also use it on some of the M2 killers and replace STBFL with something like Undying. Nemesis for instance is really scary on this build, especially after the recent buffs. Blight will also leave survivors hopeless to not die in seconds. It can be noted that Enduring is not absolutely integral to this build and could be replaced with Bamboozle or Crowd Control as we otherwise lack means of combating windows, but I personally enjoy Enduring way too much, and would rather max. out on synergies that make Dissolution better here.

Play With Your Food + Friends 'Til The End + Furtive Chase + Make Your Choice - The goal here is obviously to always go for the Obsession, getting PWYF stacks and ideally downing them in one hit thanks to Friends or MYC. If you can't find the Obsession at the start of the match that's not a big deal, as hooking anyone else will show you where the Obsession is. Once you have farmed your PWYF stacks and hooked the Obsession, you will then get additional Haste as well as Undetectable from Furtive, and get a new Obsession to go after, revealed to you by Friends. Once anyone unhooks, they will become the Obsession and Exposed, again making for easy stacks and an easy down. A really neat build that is really rather potent on a few killers (Wraith and Clown (perhaps with Pinkie Finger instead of MYC), Dracula and Vecna, Freddy, Plague (again replacing MYC with something else, such as Flood Of Rage or Nemesis)).

A sort of related build that can be used on a wider variety of killers rather than only those that are well-suited to abuse PWYF consists of Lethal Pursuer, MYC and Flood Of Rage. Any unhooker will become Exposed and have their aura revealed to you for 9 seconds, making them easy prey, especially because a lot of survivors once they get afflicted with MYC have a tendency to hide immediately, not knowing that Floods is revealing them. You will pull a lot of people out of lockers.

Dragon's Grip + Nowhere To Hide + Unforeseen + Trail Of Torment - You kick a gen, check whether and where there are survivors around it, position yourself such that they can't see you, and then get the jump on them if they touch it. As they grow wary of Dragon's Grip over the course of the match, you can often leave gens freely and survivors will be too afraid and confused by both Unforeseen and Trail to touch them, often simply hiding around them for long periods, wasting a ton of their time. Plus it's not like you can't come back if you're elsewhere when they touch it either, and with you still or again being Undetectable, you can still get the jump on them. They may have even stopped the regression on the gen, allowing you to potentially find them with NTH.

Ever since they've reduced the cooldown on Grip, the perk is really not to be underestimated. It can give you free downs, easier downs, and a whole lot of slowdown due to survivors being scared to touch any gens you kick. Things like Oppression and Eruption would obviously also go well with this, were one to not refrain from using slowdown perks.
