Thaumic Restoration Mod 1.12.2 originally was supposed to add some Items form Thaumcraft 3 back in, but now it?s more or less a collection of things that haven?t got ported to 1.12, so have fun with it.
A Crystal Infuser, based on Essential crystals (obviously)
Different kinds of Infused Thaumium
A Block that is toggleable from solid to permeable
A Wand, that can be charged with aura (Works like Salis Mundus and has a few extra recipes)
