Using spells also progress intelligence - but it is gated behind finishing Sarbina's Quest. Once you have the spell that costs 30 energy to cast you will gain either 1 witchcraft progress or 1 intelligence progress with each cast.Guys, intelligence increases by 2 points, when you ask Mira to teach you how to read. But I noticed that, when you go to get the book for Lucius in Gewn's house. The Hero must pass a check in front of the bookcase, to understand which book to bring to Lucius. It is at that moment the game assigns 1/20 to intelligence. As if, the more you try to read, the more you have the opportunity to get 1 free point in intelligence. Does anyone know if there are other books, where to try to raise that stat? I know that by leveling up I can spend points there. But if I can get them for free it's always better
Also because according to that check, if the game assigns 1/20, surely after 20 there will be 1/50. So the points obtainable for free by trying to read I assume are 2. For a total of 4 with Mira's 2.
Edit 1
I found a second book in Mayor Giron librery. After you read the book 2/20.
So there are more book to read to gain more exp and level up the intelligence for free.
A tip to get it over with is doing non-quick combat with the Orcs in the ruins or deep darkwood areas prior to killing the Orc who killed Marcus. There should be 2 orcs, one slayer with a scythe and one smaller orc. Kill the big boy and then use drain energy on the smaller orc. This will prevent the smaller orc from doing anything at all, it'll literally pass every turn not attacking or using any abilities. Then just alternate between Defend and Drain Energy until you have +2 Witchcraft and +2 Intelligence (100 total casts or less, depending on previous progress with said talents).
