Randomizer Connections
Randomizer connections expand on the randomizer 4 mod, doing anything from randomizing a few new locations to adding new charms and areas. These can be installed with your mod installer of choice and then toggled on in-game in the "connections" menu. See the mods page for instructions for setting up mods.
Modders are cooking up new things all the time, so this list might not always include every connection. As you can see, there are a lot!
Access Randomizer Randomizes access to several locations, such as adding unique keys for simple key locations and randomizing each chain in the Black Egg Temple.
Alphabet Rando Randomizes each letter of the alphabet individually, so that you have to learn to read each letter for them to be visible in the UI. Yippee literacy!
Bench Rando Randomizes benches in various ways, such as placing them as pickups similar to how stag stations work in regular rando. (Interacts with benchwarp in that benches cannot be warped to unless they have been sat on or picked up.) Also can add extra benches.
Breakable Wall Randomizer Randomizes breakable walls, dive floors, and collapsible floors. Also adds a shop at Myla where walls can be "sold" for items.
BugPrince Adds some mechanics from the game Blue Prince to Hollow Knight transition randomizer.
Combat Randomizer Adds the option to make each nail damage point an item, split charm notches and grant the option to reduce soul gain from nail slashes or to periodically drain soul.
Corpse Dream Rando Randomizes the dream dialogue of corpses scattered around the map. Nosk has never been this worth it!
Curse Randomizer Adds various debuffs called "curses" to the randomization pool which mimic the appearance of normal progression items.
Darkness Randomizer Randomizes which rooms are dark and require Lumafly Lantern to be illuminated.
Extra Rando Adds some fun miscellaneous settings and check locations, including randomizing hot springs, colosseum access, pantheon access, Bardoon's butt, WD 5 and GPZ 10, split fireball, split shade cloak, and No Logic mode!
Fishing Adds a fishing minigame where randomized items can be fished up at several fishing spots near bodies of acid or water.
Flower Randomizer Adds a location for delivering the delicate flower to certain NPCs.
Geo Rando Randomizes individual pieces of geo from geo rocks, geo chests, grubfather, and colosseum trials.
Godhome Randomizer Randomizes certain Godhome elements, such as adding locations at Hall of Gods bosses, pantheon bindings, and pantheon lifeblood.
Grass Randomizer Randomizes grass, in case you felt like geo rocks didn't make Greenpath check-dense enough.
Knight of Knights A connection created for the Holloween plando, which can also be used in normal randos. Plando spoiler (click to show)
Lore Randomizer Randomizes some lore-relevant locations including NPCs, dream dialogue, and Shrine of Believers statues.
Lost Artifacts Adds various useful objects that can enhance your nail in diverse ways.
MajorItemsByAreaTracker A tracker for your rando that allows you to play the semi-spoiler format All Majors, in which you collect every major item in every area, while knowing how many are in each area. Configurable to change what is a "major item".
MilliGolf Adds 18 golf courses to the game featuring Millibelle the Golf Ball. Randomization settings include randomizing access to each course, adding a check at course completion, and adding a check for completing all courses under a certain total number of hits.
More Doors Adds additional locked doors around Hallownest and keys to open each of them. Now you have to work for your access to Hornet 1.
More Locations Adds check locations to the game that don't have an associated item in vanilla, such as the egg in stag nest.
More Stags Ever felt like some areas of the game were just...missing something? This connection adds over a hundred new potential stag locations around Hallownest. Finally, you can stag to Crystal Peak!
Murder Rando Places a check at murdering Myla and the Nailsmith. You monster...
Not Spikesmas A new item that works similar to Not Swim/Isma's from Rando Plus. After obtaining Not Spikesmas spikes will no longer damage the player, but they will still be hazard respawned.
Pale Court Charms Adds all the charms from the mod Pale Court to the pool.
RandomizableLevers Allows you to randomize levers into the item pool. Hitting a lever will give you an item rather than opening a door, and you can find lever "items" that trigger the respective door opening.
RandoPlus Arguably the most popular randomizer connection. It adds multiple different things to randomize, most notably Nail Upgrades, Mr Mushroom, and allowing two items to appear at the same location.
Rando Zoom Zoom Start with items that make early game faster. Options include starting with Dashmaster + Sprintmaster or Gathering Swarm.
ReopenCityDoor Reopens the door between the City of Tears elevator room and Fungal Wastes (above Elder Hu). Optionally it can be made to require a key.
Rope Rando Randomizes the Watcher Knights chandelier.
Scattered and Lost Created for the HK8Y plando but can be used in normal randos as well. Plando spoiler (click to show)
Scatternest An add-on for ItemSync that allows you to have multiple different spawn locations, causing co-op players to not spawn in the same location. If you play co-op Itemsync a lot, this mod is for you.
Skill Upgrades Randomizes some upgrades for the Knight's skills, such as the ability to dash multiple times in the air or dive horizontally.
Spicy Rando A bunch of fun difficulty increases from various plandos, all condensed in one mod that can be used in normal randomizer seeds!
The Glory of Being a Fool Randomizer Adds a check at the end of Colosseum trial 3.
The Real Journal Rando This mod can randomize all journal entries not included in the base randomizer 4 settings, with various options to tweak which entries are included. Hunters Notes can also be randomized.
Trando Plus Adds some additional transition rando options, such as randomizing only door transitions.
Transcendence Adds 15 more charms to the randomization pool with some fun new abilities.
TreasureHunt A tracker for your rando that allows you to play the semi-spoiler format Treasure Hunt, in which you are given a list of the exact locations of major items and must collect all of them. Configurable to change what is a "major item" and how many locations are revealed at once.
UnRando Fixes the order of items obtained so that two players playing the same seed will always obtain the same items in the same order, regardless of what locations they checked. Rarely used outside of randomizer races.
Vendor Rando Randomizes the locations of shopkeepers so that they can appear at any* randomized location.
* Terms and conditions may apply.
Yet Another Rando Connection Yet another connection that adds settings. Like soul jars and vines, if you are normal, or jelly egg bombs and Oro's scarecrow if you like your randos more on the unhinged side.
Custom Injector Mods
These mods do nothing on their own but can be used to customize the randomization on a deeper level than the base randomizer mod allows.
If you want to make packs for these yourself, be sure to read their READMEs for detailed instructions. Alternatively, the randomizer connections channel in the speedrunning Discord has a "Custom Injector packs" thread where many people have shared theirs.
Custom Constraint Injector Can be used to define which items can be placed at which locations.
Custom Group Injector Can be used to add new groups to the randomizer, similar to the base randomizer 4 Split Group Randomizer but with more customization.
Custom Logic Injector Can be used to customize the logic for items and locations (i.e., what items and skip settings the player needs to have for a given check to be considered obtainable).
Custom Pool Injector Can be used to customize which items are considered to be pooled together so that they can be toggled on or off at the same time.
