First let’s rewind a little and talk about exactly what spellcrafting is and how it will work in ESO. Spellcrafting will be introduced at the conclusion of the Mages Guild questline. That quest line finishes with the reclamation of Eyevea which is a mage refuge devoted to research and to learning a greater understanding of magic. By reclaiming this island, you have unleashed the researching might of all the mages in Tamriel. One of the first things they discover are ancient doorways that are hidden throughout the world that belong to some culture no one has seen before. It is behind these doorways that your spellcrafting adventure begins.
Behind each doorway are ancient classrooms with rune tablets that contain ancient inscriptions. Sometimes these tablets are in relative pristine condition - for example the first one you find during the introductory quest of the system. Other times the rune stone is in fragments and you’ll have to find all the pieces before you are able to understand the entire rune stone. Some stones may even be broken into as many as five pieces. When finding only a piece of tablet, there will be clues as to the locations for the rest of the pieces.
You do not take the rune tablet (or fragment) with you, instead you will use paper and charcoal to make a rubbing of the stone in its place and add it to a spellcrafting “portfolio” book. The “paper and charcoal” will always be in your possession similar to your pickaxe or wood axe. The interface for this “rubbing” is interactive in nature and may require some precision. Once you’ve collected all the pieces to a whole rune tablet, you will have just one part of the spell crafting puzzle.
Now that you have the base spell “recipe”, you will need to procure a new tablet on which to transfer the spell. Base (white) tablets can be purchased right in Eyevea if you wish to get experimenting right away. However rarer tablets can be procured in the world (presumably by scavenging similar to woodworking and blacksmithing). There will most likely be 4 tablets qualities above the base tablet (fine, superior, epic and legendary). My best mining efforts put these materials as Basalt, Granite, Marble and Obsidian - but I'm not sure. Just like in enchanting, the better the material the more powerful the spell.
Now that you have the base spell and a fresh tablet, the last part of the spellmaking process is to choose one of six “focuses” to give the spell. A focus is similar to a morph. Any spell crafting spell can be used in one of six ways with each bringing a unique set of advantages and disadvantages. These terms and how they work will become clearer when you look at the actual spells.

When first picking up the spellcrafting quest line (tutorial), you will receive a new Spellcrafting skill line just like all your other crafting professions. There will be spellcrafting passives that will help make your spell crafting easier. For example maybe a hireling for tablets or a “Keen Eye” perk to make finding those tablets in the world a little easier - no passives exist in the code yet.
In addition to this new Spellcrafintg skill line, each school of magic also has its own skill line associated with it. For example upon first learning the Conjure Flame Atronach spell you will also receive the Conjuration skill line. These skill lines go up to level 50 and have their own set of passives that help make the school of magic more powerful, cost less resources, have the effects last longer, etc. The most important of the passives being the number of spells you can memorize from that school of magic. There are currently five schools of magic in the spellcrafting system: Destruction, Alteration, Conjuration, Illusion and Restoration. And just as placing and using skills on your hotbar will level up a skill in the base game, so too will these new skill lines associated with spellcrafting.
Once you learn a spell, it is permanently added to your library of spells. You aren’t limited to just one type per base spell. If you wanted to create a Flame Atronach spell in all six focuses, you are free to do so. Like all other crafting professions, the completed tablet is not bound to your account and can be traded or sold in your guild store/kiosk. Making master spellcrafters very valuable in the game. To learn a spell you use the completed tablet which consumes it.
