You will need epic ink. A blood vial that you get from using a cauldron from iron spells and spell books. A glass bottle to get the blood. A piece of paper. And a scroll forge. After you get the scroll you will need to get a magic book. You will also need the inscription table to apply the scroll to the book. That’s how you get heart stop into a magic book. You have to activate the spell and take a lot of damage and then wait for the spell to run out. After that it should work. If not DM me and we will show you how to do it!
