Custom Enchant books of the same type and level can be combined and leveled up through use of /Alchemist. Alternatively, if a Custom Enchant is already applied to a tool, weapon or armor, adding another Custom Enchant book of the same type and level will cause a level up as well.
Each Custom Enchant book has a random Success and Shatter rate. These are the chances of the Enchant either applying to the tool/armor piece, or shattering the tool/armor piece. If the Custom Enchant fails on an item, the book is lost and the item shatters.
Magic Success Dust can be drug and dropped onto a Custom Enchant book to increase the Success rate by the percentage of the Dust. These can be obtained from Monster drops, as well as trading for them in /tinkerer. Magic Success Dust percentages can be anywhere from 1% to 100%.
A Randomization Scroll will randomly change the success and dust rate of any custom enchantment book it is applied onto. Players often use them on books that have a poor success rate. Randomization Scrolls can be obtained through mob drops.
Protection scrolls prevent an item from being shattered due to a failed Enchantment. However, the book is destroyed. Protection scrolls can be obtained through mob drops.
A scroll which will randomly remove a Custom Enchantment from the tool or weapon it is applied onto. The removed custom enchant will be reverted back into book form with a 100% success rate. Simply drag and drop the Black Scroll onto the desired tool or weapon to have a random custom enchant removed. Black Scrolls can be obtained from Monster drops.
The Alchemist is like an anvil for Custom Enchants and Magic Success Dust. To access the Alchemist you can use the command /alchemist. Once open, the GUI allows you to place 2 Custom Enchantment books of the same type and level to create a new book, but the new book will be 1 level higher. The same applies to Success Dust, if you are trying to combine a 12% and 33% dust, you will get a 45% dust in return. However, using the Alchemist does require vanilla XP to complete and can be checked by simply hovering over the red glass in the GUI.
The Tinkerer allows you to trade Custom Enchantment books for EXP/Secret Dust. The tinkerer can be accessed by doing /tinkerer.
There are three different levels of Secret Dust depending on the rarity of the books exchanged. The tiers of Secret Dust are Legendary, Rare, and Common. Legendary Magic Dust has the highest chance of becoming a high percentage Magic Success Dust, while Common Legendary Dust has the lowest.
