@jenx, Actually at the end of the video the game did crash, a result of picking up a third invisible item in the inventory bar. The results shown in the video are displaying a change in the way the game interprets the items, the actual items do not change at all. If I were to save the game in a state like this, then quit and reload, all the items would return to the way they were before the change. Unfortunately I don't have a way to reproduce this consistently, and returning back to a 'normal' state is unlikely without quiting and restarting the game. It's not very likely that I would be able to turn this into something that can be used, unless by some chance I start learning how to disassemble, trace the code execution, and find a way to push the needed data for the purpose of arbitrary code injection... not going to happen. Just looking at assembly gives me a headache trying to understand it, maybe someone else out there could do something with this?

Could this be turned into a form of arbitrary code injection?

I honestly don't know, but maybe someday this will turn into something usable.

@djeez But would it be considered a pre-existing save if it was using only one save with no backtracking with another save? You could go to Sadie's shop after making the elixir and save outside her door, go inside and use the lantern, reload that save and run to the back of Bruno's Lodge to save and quit from there. After restart and loading the same save you would be right at the entrance to the caverns. Or would it still be considered a new category because of the quit and restart to fix the corrupt memory? EDIT: Looking again at the time spent to set up added with the time to restart and reload takes longer than just running through the part that was skipped. Better off not using it at all.

More testing with the lantern glitch led me to find it works in the following places:

• Victor's shop in Gladstone
• Petricia at the marina in Southland
• Dawn in the back of Droek's wagon
• Sadie's shop in Yvel As for getting the lantern into the inventory bar, I'm not sure about the exact number of items needed but I think it's around 9 or 10 to get it from the Thug's Cave, and it's a lot more to get it from the Draracle Cave. Here are the steps I use to set up the glitch:

1. Buy all Nathaniel's aloe/ginseng after returning from southland
2. Copy and use them to make illegal items by clicking the swords by the fountain to reduce hp
3. Go to Thug's Cave to place items from first load into illegal items
4. Back to Victor's shop, save game

An interesting side note which fueled my curiosity to discover this glitch, this was the result of my first test when I used the lantern item in Geron's office.

@djeez Yes, that's the sequence of events I have right now. There might be other places where the glitch works that I didn't test yet. If there is another spot where this works after the draracle cave, glitching the lantern into the inventory bar from the draracle cave would also work.

@PLANET Unfortunately, the elixir has to be prepared first before glitching into the caverns. Trying to use the crucible on Richard without doing so will not work, Baccata just comments about having to heal Richard quickly before the poison kills him. Another problem with this is the game has to crash and restart for this to work (unless I find another method), not forcing the game to crash by loading a game a second time will eventually lead to the game hardlocking. (EDIT: exiting the game instead of forcing a crash would also work)

@jenx Even though it is possible to get to the other side from Yvel Woods, the entry point to the Dungeons is blocked by an actual wall. This glitch will only allow passage through some barriers not marked as walls on the map, and every step taken with the glitch running could cause the game to hardlock (or in the best case it will crash, allowing a restart).

New Glitch Discovered! - The Lantern Glitch

Who would have thought a lantern could be used to skip past Yvel? I still haven't tested this thoroughly yet so use it at your own risk! Edit: I wonder if this can also be a skip for preparing the elixir if the item is the same before and after, possibly just triggering a game flag to proceed with the story? Edit2: No skip for the elixir unfortunately, just tested it.

Important update on using the border glitch without risk of hardlock!

One thing I overlooked and just realized which virtually eliminates the risk of causing a hardlock when using the border glitch is the difference between using the left and right mouse button in the action screen. A left click can pick up and throw items, but the right click can only pick up items and cannot throw them. So by using only a single left click to throw an item, the right mouse can be spam clicked after to catch the item in the air without any risk of throwing the copied items together causing a hardlock. The only issue left to address is finding the correct pixels on the edge of the border to click without wasting too much time...

Just did a quick test comparing save data at the start of the Yvel battle to a save just before killing the last enemy to trigger the end. There were no obvious counters that I noticed, but there was a change in data in a section from 20 sets of data 46 bytes in length at the start and increasing to 30 sets of data 46 bytes in length at the end of the battle. I think this might be just the map data for Yvel, possibly meaning that there were ten more entities on the map at the end compared to the start. I'll update when I find out more, it's been a long time since I did this stuff and i'm re-learning it all over again.

@djeez just throwing an idea out there (i'm more of a glitch hunter, not really a speedrunner so I don't really know if it's a good idea or bad idea), to avoid using the sides of the border which is risky as well as time consuming perhaps catching fired arrows or stars using the bottom border (you can just spam click without worrying about a hardlock since the illegal item just gets dropped on the ground in front of you) just to get one important item might be quicker. For example in the mines, just getting the key to Paulson by firing and catching an arrow then using two items after that to make the caught arrow become the key needed. Getting the bloodstone can be done by catching another arrow after that. White tower is probably better done the normal way, but being able to kill wraiths in one hit may make it a little easier. After getting the Xeob key in the dungeons with an arrow, using another arrow to get the Cobra figurine while getting the Dragon figurine the normal way would be safer without using the side borders and potentially less time consuming.

I don't know if my method for the Yvel battle would work any better but I usually run to Sadie's first, down to Victor's after that, then run back to Bruno's after checking the front gate to keep me in the right area when the battle's done. Thinking back on it, every time I can remember I finished the battle killing a great orc, maybe it's connected to number of orcs killed specifically? (Edit: more testing with catching arrows this way with the bottom border makes it just as risky, if the arrow hits a wall while an illegal item is on the floor it becomes invisible and it can only be picked up by stepping back a space to use the border glitch to pick it up. Firing another arrow into this space will cause a hardlock.)

A quick look at how the game creates items in a list by opening save data in HxD in 5 steps:

Step 1: https://photos.app.goo.gl/eAoT43RbEgG8WVce8 Step 2: https://photos.app.goo.gl/362NMZsFDQ9c4gJU8 Step 3: https://photos.app.goo.gl/cBCGM3twCCKnTWpFA Step 4: https://photos.app.goo.gl/hi8Hg1YrPqTvTncK8 Step 5: https://photos.app.goo.gl/MS9Y5MXHhEHH5frA6

Using the salve at the top of the list will make the game use that slot first when creating another item.

Edit1: Photo album messed up the order of the steps! I posted the images separately to be viewed in the proper order. Anyone who saw the album should look at this again to see it in the proper sequence. For some reason google counts up from 1 to 5 as 1, 2, 4, 3, 5.

@djeez, I agree that the amount of lag could be a factor, from the testing I have done, more entities in play reduces the success rate of a pick up using the border such as being surrounded by the wraiths of the white tower or in the catwalk caverns when they are full of spawned enemies. As for projectiles, yes they take the first available slot so if you create an illegal item from an aloe first and catch a projectile second, it will use the same slot as the aloe. Catching the projectile first then making another illegal item from an aloe second will use two different slots. Another possibility is if you use two different projectiles in a long enough corridor, for example a star on Baccata and a crossbow on Paulson, you can fire one and catch it to take one slot then fire both and catch the second projectile while the first is still in play to take the second slot. Keeping track of items in the item table can be difficult, in the video where I glitched the death wand onto Baccata's hands for example, the death wand is the fifth item created from going down the stairs so I needed four other items that were created by the game before the aloe on Baccata's shield hand... I had four left including a copy of the healing salve I glitched onto Kieran's hands. Another thing that can save time (and can cause problems if you forgot that you used a ginseng to cure poison, really annoying if you are trying to glitch a fireball wand into a hand) is using items without copying them still creates a free space, so if I only need the fifth item created by a level I could just use four items and copy and use the fifth item if it was created by the game after the other four items used. The way I keep track of the order of the items created is to fill the inventory bar with items in the order I picked them up from left to right, having items on the left created before items on the right makes it a little easier to keep track of if you only use items from the right side first.

@djeez, another thing you are correct about is in most cases throwing two copies of an item together will cause the game to hardlock, not softlock, but there are some rare cases that you can press the escape key to access the main menu and reload a game. Another thing to point out is when you create two copies of an item, and use one while the other is on the floor instead of the inventory bar, the new illegal item on the floor is invisible and can be picked up. Or if you leave the invisible item on the floor and go to another level to load more items, you can go back to where you left the illegal item and a new item will be created in its place.

Finding the right spot to click can be tricky sometimes https://photos.app.goo.gl/iWB1Sbv8753ktXhr8 try clicking near the top and bottom of the green boxes in this image

Here are the steps that I use:

1. Throw item to a wall with the item landing at the far end of the space ahead of you
2. Try to pick the item up using single clicks starting from the top of the green box mentioned above and trying other pixels below that until successful
3. With the item in the mouse cursor, at about the speed of a double click, throw and catch item just before it hits the wall.

@djeez, I did make a mistake when I used the words 'only choice' when I should have used the words 'best choice'. The process of glitching Kieran's attack to kill the guards is quick and simple and has a higher success rate over the others. Kieran's faster cooldown rate also means that he uses healing items glitched onto his shield hand quicker, and since might can be increased by equipping one of two copies of a weapon (like a halberd from the guards, forgot to mention this) then selling the other and removing the illegal item this makes him able to kill most things in one hit from a single attack due to his higher hit rate. Since his low attack power is no longer a factor, Kieran is the best choice to get through the game quickly compared to the others. Edit1: need to retest with other difficulty levels, the results of my testing are on ferocious dificulty while attempting to kill the first guard with underflow. (Edit2: using the sequence of copy dagger, equip and sell other dagger, buy mace then dagger, equip dagger.) Here are the results I got: Ak'shel - 0 hits out of 40 Michael - 0 hits out of 40 Kieran - 16 hits out of 40 Conrad - 2 hits out of 40

Part 9 uploaded:

Creating 5 'Illegal items' before going to the second and the third floor to get the last 2 figurines and all the keys. The very important thing to notice is copying the Noir key before using it, not doing this could cause one of the needed keys or the last figurine to not appear in the inventory bar. Baccata's one hit with his bare hands is all that is needed to finish Scotia off quickly (ignoring Kieran's little 7 damage hit, since Baccata is dealing up to 30000 damage anyway)

Even though this is the last video, there are a few points to take note of as I finish this last post here:

1. .
2. This has been a fairly recent discovery, there may be more uses than what you have seen in these videos.
3. These glitches have only been tested using the version from GOG.com. Older versions, such as the original unpatched floppy version, may give different or unexpected results.
4. These videos are just a demonstration of the glitches that I have found so far. Some time in the future I hope to make an organized, detailed tutorial in the guides section using these videos as a reference. Edit1: With wimpy monsters set, Ak'shel has the lowest chance to hit the guards with underflow damage and the others have a better chance to hit them. All my tests were done using ferocious monsters set and only using the sequence of copy dagger, equip and sell other dagger, buy mace then dagger, equip dagger. Djeez has done more work than I have on testing this which can be seen on his Twitch channel.

Part 8 uploaded (one more to go):

In the previous videos, I created 'Illegal items' to make items appear directly in the inventory bar after loading a new area. This same technique can also be used when the game creates enemies that hold key items, like the Xeob Key and the last Vaelan's Cube. Creating two 'Illegal items' before choosing to attack the Xeobs will turn them into copies of the key and cube that they carry, allowing you to skip fighting them and run to the stairs going up. Creating three more 'Illegal items' before climbing the stairs will turn them into the Cobra figurine, Dragon figurine, and a small key. Another thing some people may have noticed is that I left behind the lockpicks needed to open the door to get the Unicorn figurine on the second floor. I will be using the same method to get the last two figurines and all the keys in the last video.

Part 7 uploaded:

So after getting healing items back onto everyone shield hand, I decided to get Paulson in on the fun before going into the big battle. At the end of the battle I couldn't help but think it was less like a fight and more like popping bubble wrap...

Part 6 and Part 6b Uploaded:

Part 6:

Had a little trouble with putting this together, lost track of the item table and discovered I had just enough items in place only after sacrificing both Kieran's and Baccata's healing items(easily replaced with Sadie's healing salves later). Fighting with the RNG in this part was the problem: the areas loaded sometimes added extra great swords(dropped by wraiths) which pushed ahead the items I was trying to glitch into inventory.

Part 6b:

Short little clip on how to catch and permanently glitch in one of the projectiles used by the Wraiths of the White Tower. If you leave the level while a projectile is still traveling through the air(after catching one), it stays as an existing item since it is locked in stasis in the level above.
