Talisman of Chaos Assembly(TCA) can be used when upgrading an item (must be over +9)
through Chaos Machine. It does not guarantee you 100% success rate, however it will prevent the item from disappearing when it fails.

Important
Keep in mind that although the item will not disappear, it will become +0 when it fails.
TCA is one time use only, and it must be placed in the machine along other items in order to become effective. Here is more detailed guide.
