Let’s get cooking.
Hi, El Duende 05 here. It seems we’re not yet done with zxrobin’s
recent discovery of IST. Today I’ll teach you the ins and outs of Weapon Modifier Corruption,
discovered by Breath of the Wild player kinak.
Want a 10 shot Bow of Light? A +120
damage Master Sword with crit modifier? A 330 Hylian Shield with surf up? All of these,
and more, are possible. Let’s dig right in.
The simplest way to set up a file for WMC
is to play through the plateau without ever picking up arrows or armor, then get to a
town and create 62 arrowless offset slots. While this method works and was what I did for my
first setup file, it has some disadvantages.
First, you’d have to play through the entire
plateau. Second, you’d have to create arrowless slots instead of using memory overload, which
is slower. Third, you’d have to go all over the map to farm difficult materials,
such as dragon horns, without arrows. This also means no windbombs or regular BLSS.
You’re essentially starting from scratch.
I co-developed the following method with kinak
specifically to address all of these issues. It will let you avoid all this and reuse the
materials from a progressed save. It works on any weapon, bow, or shield and allows you to
reuse ingredients and meals between recipes.
And of course, it also allows you to transfer
your corrupted weapons back to a progressed save file without disturbing its other items,
so you won’t have to worry about duplicated key items or arrows stacks on your main save.
We’ll start with a quick 10 to 20 minute lecture on the precise mechanics and theory
behind Weapon Modifier Corruption. First we need to learn to count in binary...
** Just get to the point! **
Oh, uh, ok then! Check out this separate
video for the theory behind this glitch later if you’re still interested.
Let’s just see how it’s done.
Make some room in your inventory to
accept some corrupted weapons later. I recommend about 8 weapon slots, 5 bow slots
and 4 shield slots. These are the default sizes of those inventories in a new game.
Next we need to stabilize your key items so they won’t duplicate. If you have any
spirit orbs you should spend them, potentially finishing as many as three shrines to collect
an even multiple of four in order to do so.
You should manually save after spending
them, but first let’s setup to take advantage of a small trick that will help
us create a protected autosave later. Change your system clock to be
roughly 2 to 4 weeks in the future, then make a manual save. Change your system clock back to normal.
This just leaves Korok Seeds to deal with. Let’s go through a quick procedure to corrupt these
to 999 in order to prevent them from duping. You’ll want to do this even if you don’t
currently have any since it’ll shift them earlier in the key items inventory. We’ll
use this to skip the plateau in a bit.
I’ll cover inventory corruption with an
in-depth guide soon, but for now just follow these steps. I’ve also linked to a pastebin
of these instructions in the description if you happen to prefer text guides.
1. Start a new game and pick up the Sheikah Slate. Do not manual save and your
progressed file will be fine.
2. Leave the Shrine of Resurrection and
collect the Woodcutter’s Axe near the old man. Leave it equipped.
3. Walk over toward the Temple of Time and trigger an
autosave. Call this Autosave 1.
4. Wait around for 45 seconds so the next
autosave won’t overwrite your last one.
5. Go collect a Korok Seed, triggering
a second autosave. Call this Autosave 2.
6. Confirm you have both autosaves in your menu. If not, you should restart from step 1.
7. Load your manual save and create two offset slots
using memory overload.
8. Reload Autosave 1 and unequip the Axe 3 times. This will shift the key items you brought over out
of your IST slots so they won’t be transferred.
9. Reload Autosave 2. DO NOT PAUSE. Your GameData
has now been corrupted to have 999 Korok Seeds, but not your visible inventory.
If you pause and unpause, the game will sync your inventory and undo your
hard work. You also can’t use the quick menu, pick up an item, enter a shrine, etc.
10. Without syncing your inventory, walk somewhere else to trigger another
autosave. Call this Autosave 3. Here you can see the axe was shifted over two
squares, which should land it on the Korok Seed.
11. Reload Autosave 1 three more times. This
will shift the single Korok Seed in our current inventory to the left so it won’t block the 999
stack from being added by transferring in first.
12. Reload Autosave 3. You
should now have 999 Korok Seeds.
13. Reload your manual save to transfer in
999 seeds, overwriting the previous amount.
At this point you’ve got an otherwise
undisturbed version of your manual save with the Korok Seeds set to 999 and
the key items slightly reordered. Don’t sort them, we’re going to
do more with this shortly.
Next we’ll transfer some key items back to the
plateau save. The goal is to transfer up through just the glider. In my case this means I need 17
offset slots. Remember, we’ve already got two, so I need 15 more. Close the menu to sync
your GameData with the visible inventory.
Use memory overload to break additional slots
to cover precisely up through your Paraglider. Once you have enough, follow these steps:
1. Load Autosave 3 from the previous steps. The glider will transfer in, which means it’s
not activated yet on this save file. We need to acquire it “legitimately” during the file load
as opposed to via IST transfer to activate it.
2. Trigger another autosave. Call this Autosave 4.
3. At this point our Paraglider is not covered by our
current IST slots due to our helpful Korok Seeds. Now to activate it. Reload Autosave 4.
4. The glider should now be activated because it
was not transferred and thus able to successfully load in from the save. At this point you are able
to leave the plateau, but don’t do this quite yet. Instead trigger a final
autosave to persist the flag. If you mess up these steps, don’t worry.
You’ll just have to play through the Plateau, which should cost you no more than
20 to 30 extra minutes later.
5. Reload your progressed save to
continue generating offset slots.
Once you’re back in your progressed save,
continue creating offset slots until you’ve made exactly 60 + however many key items you
have. In my 100% save this is 83. Ideally you want to be precise here, but if you undershoot or
overshoot a little we can deal with it later by either creating a few arrowless slots or dealing
with a few duplicated materials each reload.
Eat most of your food so that the offset
reaches through into your materials. Drop and pickup important materials to move them
to the end of your list. You won’t really need more than 10 of anything since you can easily
dupe items here, so if you have more than that sell some so that you can do this without
them just ending up back in the same stack.
I recommend transferring things like Dragon Horns
and Gourmet meat that are particularly annoying to collect on a new save. You should also carry over
Fairies, Gems, and Wood to help keep you alive, generate rupees, and help you unlock the
house easily should you choose to.
Once you’ve got your inventory organized, reload
the last autosave you made with the glider active to transfer everything over
to your plateau save.
When you load in, you might
notice you have no materials. This is actually just visual. Grab a
material and it’ll unlock the tab for you. See, everything’s fine.
I recommend activating Plateau
Tower for the warp point. It’s a great launch point for
0BLSS, if you know how to do that. It’ll also unlock all the shrines, so you can
get inside without doing a shield clip.
That’s good, because I recommend you get all
the runes too. You’ll find them handy for various things later. You don’t have to finish
the Shrines if you did the steps correctly, just step in briefly to grab each
rune (and a handy warp point).
As a heads up, you should avoid picking up any
armor, even if it’s sellable, in order to take advantage of a handy cooking technique called
prompt entanglement for advanced recipes later. This was discovered by PowerGaymerKai
and I’ll cover it in a separate guide as advanced cooking is a whole
topic in and of itself. Suffice it to say this technique is only
possible with an undiscovered inventory tab.
Ok ok, kinak also found a method called Arrow
Invalid Slot involving multiple duplicated arrow stacks, but for this setup I feel the
undiscovered armor tab makes more sense. They’re both out of scope for this guide though,
so I’ll cover them later. Keep an eye out on my channel for that video if you want to learn
how to do weird things like eat Spirit Orbs.
If you’re familiar with 0BLSS, you might be
able to use that to get you quickly to town. Otherwise you can find some horses
just northwest of the plateau. Ride one over to Dueling Peaks Stable
and register it. Feel free to unlock any additional towers or warp points on the way.
Any town would technically do, but I’d head to Hateno Village since the house will come in
handy later. If your plateau skip didn’t work for some reason and you still have 4 spirit orbs
make sure to turn them in when you get to town. Activate the warp point
and trigger an autosave.
Next we’ll fill up our food to fully stabilize
our offset slots. Cook 5 to 10 apples in a pot. This will make simmered fruit with no effect
(hearty, etc.), which will always sort first in your food tab. This is helpful for promoting new
corruption recipes to the end of the list later. Trigger an autosave.
Reload this save a few times to duplicate the food
until you have all 60 slots filled, then reload one more time to get rid of the excessive
duped materials you’ve likely accumulated. Trigger another autosave.
At this point, even with all of your
offset slots, reloading this autosave will not change anything. If you reload a
save with a full food inventory like this, it will effectively overwrite the food inventory
on the target save with no further effects. This is stable and thus ideal for selectively
duplicating or transferring items.
In order to transfer N items, all
you have to do is make sure they’re immediately before the food and then eat N meals and reload the target save. You
can move materials by dropping and picking them up to shift them to the
end of the list if you have 10 or fewer, otherwise you can drop everything else after
them and reload to dupe another stack.
Before moving on I wanted to quickly
say thanks to all my subscribers. I really appreciate all the support
you’ve shown me these past few weeks, it means a lot to me. And if you’re new to the
channel, and finding this information useful, consider subscribing and turning
on notifications for more.
At this point we could technically
start corrupting weapons, but it’s best to start by collecting
some weapons worth corrupting. I recommend heading to Korok Forest
and stealing the Master Sword first. If you trigger an autosave before
stealing it using the campfire glitch, you can then transfer it to a
save from before you pulled it to leave a copy in the pedestal in
case you need to collect it later. Make sure to get the warp
point while you’re here.
Once you have this, you could head to Hyrule
Castle to collect some even better weapons. If you do this, consider duping a bunch of
fairies first so you’ll have an easier time there. The Master Sword combined with ample fairies
should make it easy. If you start getting low on fairies just dupe more. Make sure to
get the warp point so you can come back.
I recommend using a similar trick as you did
on the Master Sword to steal the Hylian Shield. This way you can always return
later to get another one, potentially with durability up if you farm up
enough XP on this file. You may also want to dupe a copy of it so you can use one while
keeping the other pristine for later.
You can also optionally steal the Bow of Light
from the DBG fight by transferring it into an autosave. This will be easier if you unlocked the
Bomb and Magnesis runes as I suggested earlier, though there are ways to beat the
boss rush without those runes. The weapons in the castle
combined with the Master Sword, infinite fairies, and a duped Hylian
Shield should make this short work.
Once you have the Bow of Light you’ll also
be able to BLSS and windbomb normally again, even without arrows. Don’t worry
about it being undroppable either, we’ll still be able to corrupt
the Master Sword later.
Once you’ve got everything you want, head back
to town. At this point it’s a good idea to sell or drop all but 1 to 2 of each material to make
clearing your inventory later quicker. Just make sure you don’t drop the last of any material
you don’t want to have to farm for later.
If you carried over gems and wood, you can use
them to purchase the house, then upgrade it. Buy at least one bow mount,
it’ll come in handy soon.
Before we proceed any further, it would be an
excellent time to lock in some of this progress. At this point, if you made a future
manual save as recommended earlier, you can do something similar now to create a
protected autosave. Change your system clock to be a date in the future, but earlier than your manual
save (1-2 weeks). Then, trigger an autosave. Return your clock to normal.
From this point until time catches up with your
future autosave, it will not be overwritten. Thus, you can transfer materials or weapons out of this
save using IST anytime you need them should you run out later. An ideal save here will have a
still undiscovered armor tab, undamaged Hylian Shield, all materials still in inventory but sold
down to manageable levels (perhaps 1 to 2 each), and a set of hopefully undamaged weapons
from the castle suitable for corruption.
You may also need a blood moon
later for some advanced cooking, so if you see one coming, head to Hyrule Castle
or duck into a shrine at midnight to preserve it. Ideally the protected autosave is
made just before the blood moon has occurred to minimize waiting time.
It’s finally time to get cooking again.
Select a category of weapon to corrupt. It’s
most efficient to corrupt weapons, then bows, then shields. In order to do this though we’ll
have to temporarily store the Bow of Light. Do the following:
1. Fill the rest of your bow
inventory with regular bows.
2. Attempt to place the Bow of Light on a mount
to move it to the end of your bow inventory and clone it onto the mount.
3. Run across the bridge and back to verify the Bow
of Light is on the mount.
4. Trigger an autosave.
5. Sort the Bow of Light back to
the front of the bow inventory.
6. Drop your shields and materials and eat a meal
so your offset includes the last regular bow.
7. Reload the previous autosave to transfer the regular bow into the inventory
and shift the Bow of Light off the list.
8. Sync your inventory (open and close your menu) and trigger an autosave.
At this point you should have the Bow
of Light stored on a mount for later but full access to corrupt your weapon
tab. Let’s start corrupting weapons.
Trigger an autosave. Eat a meal, then cook the desired recipe.
This one grants guard up, surf up, zoom,
multi-shot, “long” throw, crit, and attack up. All at the maximum possible value of 120.
It does require prompt entanglement though, which will be covered in a future guide,
so here’s an easier recipe for now.
This one grants multi-shot, “long” throw,
crit, and attack +105. You can use this for a 10 shot Bow of Light. Or for shields,
you can try this one for guard up 120 and surf up. Check the recipes spreadsheet
linked in the description for other options.
Make sure the food tab is filled
completely, has no stackable food in it, and has your desired food in the last slot. Drop everything to the right of the current
tab you’re targeting except for food. You want an uninterrupted inventory
between food and that tab.
Perform the following steps
to corrupt a target weapon:
1. Drop and pick up a target weapon
to move it to the end of the list.
2. Trigger and reload an autosave to apply the 60th meal’s
effect to the target weapon.
You should be able to repeat these steps
for up to the entire weapon tab.
Once you’ve corrupted everything
other than the Master Sword, you can use an IST shift to move it to the end of
the inventory to corrupt it too. Here’s how:
1. Eat enough meals to cover all
weapons right of the Master Sword. Be precise.
2. Reload the previous autosave.
The other weapons should be transferred in to
the left of the Master Sword, allowing you to corrupt it too. Afterwards, sort your food
to bring your target recipe back to the end. Then just autosave and reload for your corrupted Master Sword.
Once you’re done with each recipe or
weapon category, create an autosave and then transfer the next
set of materials or weapons back into it from your protected autosave.
The procedure is the same as before. To transfer these 8 bows and shields, I drop any
intervening materials I don’t want transferred, eat 8 meals, then reload the target autosave. Remember to sort your meals again
before your next round of corruption.
Then repeat for the next recipe or weapon
category from the “Corrupting Weapons” chapter.
When you’re ready for the Bow of Light,
pick it up from the mount and it’ll already be at the end of your inventory. Then just
corrupt it like usual. Generate an autosave, then reload it to corrupt your Bow of Light.
As I mentioned earlier, this recipe
grants zoom and cluster 10 shot.
If you also want a spread fire Bow
of Light, you can dupe one easily. Drop or stow a bow first if you need to
make room, then just generate an autosave and fetch another copy from
your protected autosave.
In this case I fetched my
shields at the same time. Now we’ve got a second Bow of Light to
corrupt with a different recipe later. As usual, remember to sort your meals to
get your target recipe back to the end.
At this point I’ve explained all you’d need to
know to finish corrupting the rest of your gear. The exact steps will vary based on
your inventory and desired recipes, but let’s quickly watch the rest
of the steps I took for my gear.
When you’ve completed all 3 weapon tabs, transfer
everything back to the protected autosave (or in my case, an earlier
autosave with materials) and then trigger a new one.
It’s possible to go back and
corrupt more weapons later, even purchase more slots in order to do
more total, but you should be able to figure that out on your own later now that
you’ve got some experience with WMC.
There are a ton of recipes available.
Here are some fun clips submitted by users of my discord server. I’ll include
their recipes in the description.
When you’re all done corrupting
weapons, drop all materials and eat all food, then drop any
gear you don’t want to transfer and reload your manual save
to transfer the items there. Check to make sure nothing was
duplicated that you didn’t want, then close the menu to sync your inventory.
If you transferred in a corrupted Master Sword,
you’ll notice it took on the upgrade level of the file you transferred it into. Entering
Trials of the Sword will remove its modifiers, so make sure to complete them before you transfer
if you’d like a 180 Master Sword. Don’t worry about the duplicate one either; it’ll be removed
automatically if you save, close, and reload.
Generate a new autosave, then close the game to reset your offset.
At this point you have a choice. If you don’t mind
having 999 Korok Seeds permanently on your file, load the autosave with corrupted
weapons and make a manual save. If you do mind, load your manual save, generate
enough slots to cover up through your Korok Seeds, and transfer them into your
post-corruption autosave to rewrite them back to the
previous number. Then autosave, close, reload to check your inventory is ok,
and make a new manual save if satisfied.
And that’s the end of the tutorial. I hope
you found it informative. If you want more information about IST or WMC, please join
my discord and the speedrunning server.
I wanted to give a huge thank you to
kinak for working with me on this guide. It wouldn’t have been possible without him.
I also wanted to thank the members
of my discord and the speedrunning server who’ve helped me with research and
ideas for incremental improvements.
A special shout out to Ekkornkorn, Linkus7, and
NaN Gogh for testing out kinak and my 999 Korok Seed steps in preparation for this guide.
Lastly, thank you for watching!
