Prerequisite: Intelligence 15 or higher, Ritual Book
You gain a spellbook containing the repository of the arcane spells you know.
- Your Ritual Book is turned into your Spellbook for purposes of containing your knowledge.
- Each time you learn a spell from an Arcane Spellcasting Feat, you can add one more Arcane spell of your choice to your spellbook.
When you find an arcane spell in written form, such as a magical spell scroll or a wizard's spellbook, you might be able to add it to your spellbook. The spell must be on the arcane spell list, of a spell point cost you can cast and you need the time and skills to decipher and copy it.
- The process of copying a spell takes 2 hours and costs 50 gp per level of the spell. The cost represents material components you expend as you experiment with the spell to master it, as well as the fine inks you need to record it.
- When you copy a spell from a spell scroll, you must succeed on an Intelligence (Arcana) check with a DC equal to 10 + the spell's level. If the check succeeds, the spell is successfully copied. Whether the check succeeds or fails, the spell scroll is destroyed.
- If you copy a spell from your own spellbook you only need to spend 1 hour and 10 gp for each level of the copied spell.
If you lose your spellbook, you can transcribe the spells that you have learned or prepared into a new spellbook. If done by memory, this requires an Intelligence (Arcana) check against a DL of 10 + the transcribed spell level. On a failure, the transcribed spell is not completed correctly, which is known to you, and can't be attempted again until you have had a look at the spell in written form.
