The Inscription Table is the block in Iron’s Spells ‘n Spellbooks that’s used to write Scrolls into a Spell Book. Each Scroll you put in fills one slot in the book, and the spell can then be cast as often as your mana allows, instead of the Scroll being used up after a single cast.
It works the other way as well, as a spell that’s already in a book can be taken back out as a Scroll at the level it had. That makes it one of the first blocks you’ll want to make, since every spell you collect goes through it at some point.
Obtaining
The 
Inscription Table is crafted from a 
Book, three wooden 
Slabs and two wooden 
Fences, and any type of wood will do. It’s two blocks wide when it’s placed, a bit like a double Chest, so you’ll need two empty spaces side by side to set it down.
You might not need to craft one at all, as they’re already placed in a few of the mod’s structures. The Mountain Tower, the Evoker Fort, the Mangrove Hut and the basement of the Pyromancer Tower all have Inscription Tables you’re able to use on the spot.
It’s broken fastest with an Axe, and it’ll drop itself so it can be moved to your base. The table can be waterlogged as well, which means it’ll sit in a flooded room without the water needing to be drained first.
Usage
Opening the table shows a slot for a Spell Book, a slot for a Scroll and a grid of the book’s spell slots, with the details of whichever slot you’ve selected on the right. If you’ve got a Spell Book equipped in your Spellbook slot, it’s loaded into the table for you, and it goes back to that slot when you close it.
Writing a Spell Into a Book
To add a spell, you’ll need to put the Scroll in its slot, click an empty spell slot in the book and press the button next to them. The Scroll is used up and the spell goes into that slot at the same level the Scroll had, so a level 5 Scroll will give you a level 5 spell.
A book can’t hold the same spell twice, and you can’t write over a slot that already has something in it. If the book is full, you’ll need to take a spell out first, or give the book another slot with a 
Lesser Spell Slot Improvement at the 
Arcane Anvil, which adds one at a time up to 12.
Taking a Spell Back Out
Clicking a spell in the book shows its stats on the right and puts a Scroll of it in the result slot. Taking that Scroll out removes the spell from the book and frees the slot, and the Scroll keeps the same level, so nothing is lost by moving spells between books.
This is how you’ll level up the spells you already use. Take the spell out as a Scroll, add a bottle of Ink that matches the rarity of the next level at the Arcane Anvil, and then write it back in at its new level.
Some books come with spells that are locked into them, which are the Grimoire of Evokation and the Necronomicon. Their locked spells won’t come out at the table, although a higher level Scroll of the same spell can replace one at the Arcane Anvil.
Reading Spell Details
The panel on the right is useful even when you’re not changing anything. It shows the selected spell’s school, level, mana cost, cooldown and what it does, so you can compare two spells before deciding which one is worth a slot in your book.
Eldritch spells are the one exception, as their names and stats show up scrambled until you’ve learned them with an Eldritch Manuscript. Once a spell is learned, its Scroll can be written into a book like any other, and the panel will show its real details.
FAQ
Writing a spell into a book uses the Scroll, but the spell isn’t lost, as it’s now in the book at the same level. You’re able to take it out again later as a Scroll, which gives you back exactly what you put in.
It’ll usually be because the book is full, or because the same spell is already in it, as a book can’t hold two copies. Selecting a slot that already has a spell won’t work either, so you’ll need an empty slot picked first.
The three spells it comes with are locked, so they can’t be taken out at the Inscription Table, and the same goes for the four in the Necronomicon. The free slots in those books work like any other book, though.
There are tables already placed in the Mountain Tower, the Evoker Fort, the Mangrove Hut and the basement of the Pyromancer Tower. They’re free to use where they stand, and they’ll drop as an item if you break one with an Axe.
