This mod allows you to right-click on a cauldron with a heat source (magma block, fire, soul fire, campfire, soul campfire, lava) below it in order to melt gold block, and right-click on a cauldron holding molten gold block while holding an enchanted item in your main hand to consume the gold block and raise all enchantments on the enchanted item by 1 level, as well as add/raise the gilding enchantment by one level. When the gilding enchantment reaches level 3, the item will no longer be able to be gilded.
Special Tip:
In the vanilla enchantments, the mending, silk touch, and multiple shot enchantments will not increase even if their levels are forced to rise after reaching a certain threshold; the actual effect of enchantments such as sweeping is constrained by other game mechanics, which impose an upper limit or make it infinitely close to the limit; and in particular, excessively high levels of enchantments like quick charge (higher than level 5) and Lure (higher than level 5) will render the item unusable.

本模组允许你右键下方有热源（岩浆块、火、灵魂火、营火、灵魂营火、熔岩）的炼药锅以熔化金块，并主手持附魔物品右键盛着熔化金块的炼药锅消耗金块来使附魔物品的全部附魔提升1级，同时添加/提升一级镀金附魔。当镀金附魔达到三级时，物品将无法再次镀金。

特别提示：原版附魔中，经验修补、精准采集、多重射击等附魔达到一定等级后即使强行提升等级效果也不会提升；横扫之刃等附魔实际效果受其他游戏机制约束存在上限或无限接近的情况；尤其是快速装填（高于5级）、饵钓（高于5级）等附魔等级过高时，会导致物品无法使用。
