Integrated Spellbook

You have combined your knowledge of transcribing spells with your warforged physiology. You gain the following benefits:

• Your spellbook is now a part of your body, and cannot be destroyed unless your body is also destroyed.
• You can change your list of prepared spells when you finish a short rest instead of needing a long rest.
• Copying spells into your spellbook no longer requires ink, but still requires 50 gp per level.
• Copying spells into your spellbook now only takes 30 minutes per level instead of 2 hours per level.
