When discarding a Scratch Card, the game stops correctly updating some pointers regarding the Equipment Submenus.
Relevant for Transmutation/Duplication, these pointer references to what Equipment, including Level and Jewels, gets discarded.
This effect is cancelled when fully closing the Menu.

Equipment Transmutation:

• Copies the First Item of an Equipment Submenu
• The Current Equipments can be used as well. First Item of that is the Weapon
• Transmutates only from the same Submenu
• Step 1 can be skipped if selecting the same submenu as last time (Default: Weapon)

1. Go into the Item Menu and open an Equipment Submenu to do transmutation in.
2. Return to the Base Menu, open the Scratch Cards Menu and drop any 1 Scratch Card.
3. Return to the Base Menu, open the Item Menu and go into any Equipment Submenu.
4. Drop any Item you wish to Transmutate.

Alternative First Step:

• Go into the Status Menu and Open the Equipment Submenu.
• This Selects the currently Equipped Weapon for duplication and the Weapon Item Submenu to Transmutate from

Scroll and Infinite Transmutation:

• Requires 1 Scratch Card
• Copies the result of an Equipment Scroll
• Can skip Step 1 if selecting the last selected Submenu again (Default: Weapon)
• Can go to Step 4 after either an Equip or Scroll Transmutation to continue quicker

1. Go into the Item Menu and Open any Equipment Submenu with Items in it.
2. Return to the Base Menu, open the Scratch Cards Menu and drop any 1 Scratch Card.
3. Return to the Base Menu, open the Item Menu and go into the Scrolls Submenu.
4. Highlight whichever Equipment Scroll you wish to create.
5. Drop any Equipment Items you wish to turn into the Crafted Item.

Additional Info

• If the Created Equipment is from a different Submenu, The Item from that Submenu in the chosen Item Slot will be discarded.
• You will be able to discard further, even if there are no more Items in that Submenu at the chosen Item Slot. In this case you will turn nothing to something.

Common Issues:

• Fully closing out of the Menu Cancels the Glitch.
• THE GAME CRASHES if the last Item or Scroll Page you opened while Marking what you want to create was empty.

Thanks to Priestess Emilia for bringing this Glitch up in the Discord. There is so much more info on how this works on a more technical level on the discord that is fully skipped over for this guide!
