Enchant Magic item
There are many ways to Craft Items, magical or otherwise. When it comes to Crafting a Magic Item there are many routes as well.
One is very complicated and hit-or-miss where you need a formula, time, money, and items—this is the traditional 5E by the book crafting. Crafting Magic Items
There is a system where one creates focal stones and through a complicated, time-consuming and expensive process enchant items. Crafting Magic Items with Focal Stones
There is another system of Gem Magic where you can enchant gems and then use sockets to change the enchantment as well. Crafting and Using Gem Socket Items
Residuum & Magic Item Crafting
And here we explore a different system utilizing Residuum. With a bit of Residuum it is possible to create a magic item or upgrade other magic items. It is always a risk and still takes a bit of time, but nothing like the other systems. If you have just a bit of Residuum and knowledge of the Disenchant Magic Item you can always make more of this magical dust. This is currently a lost form of crafting, if used it is still done in secret. Historically when magic was too easy to obtain or manipulate it led to issues. Governments feared people rising up and the people feared governments using these to control them too easily. So, if anyone has access to these spells or how to use them -- it is a very well kept secret.Effect
Magic drawn from the warp and weft of the universe infuses the item you hold in your hands. Casting this ritual allows you to create a magic item or upgrade an existing magic item using a quantity of gold and residuum equal to the cost of the magic item (50% each).
To create a magical item, the component cost is the price of magical item. For an existing magical item that your are magically upgrading, the component cost is the difference in price between the existing item and the upgraded magical item. (based on DM's pricing)
A magic item can only be enchanted by magic users with a spell casting level that matches the rarity of the magic item according to the table below.
This spell gets the caster away from many of the other stipulations of enchanting a magic item and so the spell is never shared freely and residuum is coveted by anyone who comes in possession of it. (See chart below)

This can be frowned upon or even deemed illegal by many governments, so most wizards are very private of this method and protective of the spell and materials.
