"You can have your Book. I do not need it. I only want your attention for a moment..." Sionnie said calmly as she slid his spell book gently across the table. "I-I would like your help." Sionnie said quietly. "I want to know more.. More about my Heritage, about my Powers. I want to make a pact and i need a tome that can show me how.. Can you help?" She watched Galawayn carefully now to see how he might react.  This was forbidden magic, the kind a goody wizard like him might feel strongly against. However, She wondered if he had realized her blood lust yet in the battle against the bandit leader,  no, Not yet.

I am pretty sure there is no spell that does this. [@Natsucooldude] I tried doing a similar thing in my DnD game and the DM said that its not possible unless you are a high level caster (maybe with epic boon? Wish?). Even then he didn't mention how.

Let me know if you want to go through with this though.
