Doors Modifiers: All 80 and the Best Ones for Knobs

Doors has 80 modifiers. They make a run harder or easier, and they change how many Knobs you get paid at the end.

Most players switch on everything they can and hope for the best. That is the wrong move, because the game stops counting long before you run out of modifiers to turn on.

This page has every modifier with its exact bonus, plus the smallest set that gets you each badge.

The quick answer

Of the 80 modifiers, 70 raise your Knob bonus and 9 lower it.

Wondering how rare these badges actually are? Only 71,928 players have A Hard Place, about 1 in 7,208. Our Doors achievements guide has real player counts for all 111 of them.

The cap nobody mentions. Add every single boost together and you get +780%. The game only ever pays you up to +150%. That is 5.2 times more than you can bank, so past the cap you are making the run harder for nothing.

And +150% is exactly what the hardest badges ask for, so the ceiling and the goal are the same number.

How the Knob bonus works

Every modifier you switch on adds or takes away a set percentage. The total is your bonus for that run. Three rules decide what that total can be.

Rule	What it means
The bonus stops at +150%	Turn on more boosts after that and they pay nothing.
The penalty stops at -90%	The game will not take away more than that, so you never end up with less than nothing.
No single modifier gives more than +25%	Random modifiers are the one exception and can reach +50%.

That last rule is why the list feels slow. The roster is bottom heavy, so most of your bonus comes from stacking a lot of small ones.

Bonus size	How many modifiers give it
+50%	1
+30%	1
+25%	3
+20%	4
+15%	12
+10%	24
+5%	25

The biggest single boost in the game is Chaos, Chaos at +50%.

The four badges and what they need

Every popular modifier question is really a badge question, and each badge is just a number you have to reach before you finish the floor.

Badge	Floor	Bonus you need
Not Five Stars	The Hotel	+50% or more
Rocky Road	The Mines	+50% or more
Hotel Hell	The Hotel	+150% or more
A Hard Place	The Mines	+150% or more

You can get two at once. Finish a floor at +150% and you earn both of that floor’s badges together. That only works if you did not already have the easy one.

Why you cannot just pick the biggest ones

Modifiers come in groups where only one can be on at a time. 17 of these groups cover 52 of the 80 modifiers, so most of the list is a pick one situation.

This bites straight away. The two biggest boosts in the game cannot be used together, so the obvious plan of stacking the top few does not work.

The largest group has 6 modifiers in it, and you may only ever have one of them switched on.

Only one of these at a time	Choices
Baby Hands, Less Stuff, More Stuff, Out Of Stuff, Small Hands, Wear And Tear	6
Didn’t Skip Leg Day, Faster, Faster, Faster, MAXIMUM OVERDRIVE, My Knees Are Killing Me, My Legs Are Killing Me	5
Bad Electrical Work, Electrical Work, Lights Out, Power Shortage	4
Last Breath, Last Few Breaths, Tripped, Tripped And Fell	4
Bad Time, Good Time, Really Bad Time, Worst Time Ever	4
Always Watching, Four Eyes, Nosey, Seeing Double	4
Chaos, Chaos, How Unfortunate, Uh Oh	3
Are Those Pancakes?!, I Love Pancakes!!!, Watch Your Step	3

This is why the totals below are smaller than adding up the biggest numbers would suggest.

The fastest way to each badge

There is a second catch. 38 of the 70 boosts are locked behind badges you have to earn first. A brand new player can only reach 32 of them.

Put the locks and the groups together and a new player’s highest possible bonus is +205%. That clears the +150% badge, but not by much.

Reaching +50% (Not Five Stars and Rocky Road)

Starting from nothing, 3 modifiers is enough. These are all open to a new player.

Modifier	Bonus	Category
How Unfortunate	+30%	Random Modifiers
Power Shortage	+15%	Lighting
Out Of Stuff	+15%	Items

That lands you on +60%, just past the 50% you need.

Reaching +150% (Hotel Hell and A Hard Place)

This is where the locks bite. With nothing unlocked you need 12 modifiers. Once you own the earlier badges you need only 6.

Modifier	Bonus	Category
Chaos, Chaos	+50%	Random Modifiers	Needs a badge
Lights Out	+25%	Lighting	Needs a badge
Worst Time Ever	+25%	Entity Spawning	Needs a badge
Make Haste	+25%	Sub-Floors	Needs a badge
Last Breath	+20%	Health	Needs a badge
Four Eyes	+20%	Eyes	Needs a badge

So do the easy badge first. 9 of the locked boosts open up the moment you own Not Five Stars. Getting that one badge turns a 12 modifier grind into a 6 modifier one.

How many Doors modifiers you need for the 150 percent badges

The 9 modifiers that cost you Knobs

These make the run easier, so the game pays you less. Two of them switch your rewards off completely.

Modifier	Effect on Knobs	What it does
ADMIN PANEL	Turns rewards off	Spawn entities, items, and troll your friends! Cannot gain progress while enabled.
CUSTOM SEED	Turns rewards off	Makes room generation & most events consistent. Updates/patches may cause changes.
MAXIMUM OVERDRIVE	Turns rewards off	Movement speed is incredibly fast.
Faster, Faster, Faster	-75%	Movement speed is significantly faster.
RANDOM EVENTS	-50%	Enable random events! Includes option to let Twitch and/or YouTube chat choose events!
More Stuff	-50%	More items can be found.
Didn’t Skip Leg Day	-50%	Movement speed is faster.
Good Time	-50%	Most entities will attack less often.
Voice Acting	-20%	Activates the April Fools 2024 voicelines.

Worth knowing. The penalty never goes past -90%. So a modifier listed as costing you more than that still only costs you 90%.

The 12 modifiers that were taken out

If an older list mentions one of these, that list is out of date. Each one has a stated reason.

Modifier	Why it went
PARTY MODE	The creation of BATTLE MODE, a better and improved version of PARTY MODE.
Trick Or Treat	This event was replaced by The Halloween Spotlight Event, a better and improved version of it.
HOTEL-	This was moved to a Vision
SUPER HARD MODE!!!	This was moved to a Vision
SURVIVE THE DRAKOBLOXXERS	This was moved to a Vision
Lights On	Didn’t do enough for their existence to be justified (Could return in future updates)
El Goblino On Break	Didn’t affect anything enough to be a thing (Could return if future updates).
A Few Places To Hide	Overriden to make room for the new version of Nowhere To Hide
Again & Again & Again	Permanently removed because LSPLASH was unable to fix ‘Again & Again & Again’, and the modifier kept breaking after every major update.
You Really Can Run	Made the game easier since a longer Seek chase would mean more rooms skipped
It Can Run Too	Seek’s movement speed was reworked in The Mines Update to be dynamic instead of a fixed number, breaking the modifier and causing it to do nothing.
Roundabout	Halt’s movement was reworked in The Mines Update to directly follow the player, which would have caused the modifier to work incorrectly.

There are also 2 modifiers listed as coming later and 2 that were dropped before release. None of those are in the 80 above.

Doors modifiers FAQ

How many modifiers are in Doors?

80. The game wiki states the same number, and we counted the live list to check.

What is the highest Knob bonus you can get?

+150%. Adding more boosts after that does nothing, even though all the boosts together come to +780%.

What are the best modifiers for Hotel Hell?

Any set that reaches +150%. With the badges you already have that can be as few as 6 modifiers, and from a fresh start it takes 12.

What are the best modifiers for Not Five Stars?

You need +50%. 3 modifiers do it from a fresh start: How Unfortunate, Power Shortage, Out Of Stuff.

Why can I not see some modifiers?

38 of them are locked behind a badge. They only appear once you have earned the badge listed next to them.

Can I lose Knobs from modifiers?

You cannot go below zero. The penalty stops at -90%, and two modifiers switch rewards off entirely instead.

No. 17 groups of modifiers let you pick only one at a time, and those groups cover 52 of the 80. The two biggest boosts are in the same group.

Is there a modifier that does nothing for Knobs?

Yes, one. Bad Ventilation changes the run but gives no bonus either way.
