You can’t use the Talisman of Chaos Assembly and the Talisman of Luck at the same time. Remove one so you can upgrade the item to +10. Remember that in this case it’s recommended to use the Talisman of Chaos Assembly, because if the upgrade fails the item won’t be lost. If you use the Talisman of Luck, the item will be lost if the upgrade fails.
