Hogwarts Legacy plays exactly as normal until you unlock the Room of Requirement. From then on, the Room runs Schedule I's business: you grow, mix and deal Schedule I's real products inside Hogwarts, with Schedule I's own data, icons and sounds read from your installed copy of the game.
Features
- Nothing changes before the Room of Requirement. The mod stays completely silent until that unlock on your save. No panel, no sounds, no changes.
- Grow in the Room's herb plots. Plant Schedule I's four strains: OG Kush, Sour Diesel, Green Crack and Granddaddy Purple. Seed prices, growth times and yields are Schedule I's own. Your Hogwarts plants in the same plots are left alone.
- Mix at the Room's cauldrons. Combine your product with any of Schedule I's 16 ingredients (Cuke, Banana, Donut, Flu Medicine, Energy Drink, Motor Oil, Mouthwash and the rest). Effects follow Schedule I's mixing map, so its recipes work here: OG Kush with Banana gives Sneaky and Gingeritis, just as it does in Schedule I. All 35 effects are in, and each mix is priced by Schedule I's value rule.
- Deal to students and villagers. Everyone you approach takes one of Schedule I's 70 customer profiles, with that customer's favourite effects and spending. The panel shows who they are, what they like and your chance before you offer.
- Get reported. A customer who refuses may report you, as in Schedule I. You are then Wanted for a while, with Schedule I's siren and pursuit music.
- Curfew. Schedule I's curfew runs on the Hogwarts clock from 21:00 to 05:00. Peeves, the castle ghosts, prefects and professors are the patrols. If one sees you carrying product during curfew, or while you are Wanted, your stash is confiscated.
- Schedule I's sounds. The deal jingle, cash register, new-customer and new-mix stings, harvest snip, boiling pot, megaphone, siren and music are decoded from your Schedule I install and played as you work.
- Schedule I's item icons. Buds, seed jars and every ingredient appear on the panel with their real Schedule I artwork.
- A parchment panel in Hogwarts Legacy's own fonts. Cash, the time, your stash, progress bars for growing and mixing, and the keys for whatever you are standing at.
- One wallet. Schedule I's cash is your character's gold: seeds and ingredients are paid for in gold, and deals pay out in gold, at $1 = 1 gold. The same number shows on the panel and in Hogwarts Legacy's own menus and shops.
- Its own save. Stash, plots, mixes and customers are remembered between sessions. The only thing the mod changes in your Hogwarts Legacy save is your gold.
- Solo.
How to play
- Unlock the Room of Requirement in the main story if you have not yet. Until then the game is unmodified.
- Load your save. The first time, a parchment panel says it is reading Schedule I from your install. This takes about half a minute and happens once per Schedule I update.
- $375 is added to your gold the first time, the cash a new Schedule I game hides around town. From then on the panel shows your gold.
- Go to the Room of Requirement and stand at a herb plot (any potting table). Press F6 to choose a seed and F7 to plant it. If you have no seed, one is bought at Schedule I's price. A plant takes about 9 minutes.
- Come back when it is ready and press F7 to harvest. You get 12 units.
- Stand at a cauldron (any potion station). F6 picks the product, F8 picks the ingredient, and the panel shows what the mix will become and what it will sell for. F7 starts the mix: up to 10 units at a time, about 6 seconds each. Ingredients are bought as needed. Press F7 again to collect.
- Leave the Room and walk up to a student or villager. The panel shows the customer, their tastes, the offer and your chance. F6 changes the product, F7 makes the offer. Give a customer a few minutes before approaching them again.
- Mind the clock. After 21:00, keep away from Peeves and the ghosts while you are carrying. The Room of Requirement itself is safe.

What you need
- Hogwarts Legacy on Steam. Melty installs the UE4SS loader for you.
- Schedule I on Steam, installed on the same PC and on its default branch. Nothing from Schedule I is in this download: its products, rules, customers, icons and sounds are read from your own copy while you play. If Schedule I is not installed, the panel tells you so and Hogwarts Legacy plays unmodified.
Good to know
- Mixing and prices are confirmed against Schedule I's data. Deal acceptance, the curfew hours and the growth time scale live in Schedule I's compiled code and are re-implemented from an understanding of the game, so they may not match it exactly.
- Schedule I products live in the mod's own stash, shown on the panel. They do not appear in Hogwarts Legacy's inventory menu.
- The mod keeps its save and what it read from Schedule I in
%LOCALAPPDATA%\HogwartsScheduleI. Delete that folder to start over (your gold stays as it is).
- Tested on Hogwarts Legacy version 1613387 and Schedule I Steam build 24705572.
- Unofficial fan mod, built with AI assistance. Not affiliated with Avalanche Software, Warner Bros. Games or TVGS.
