Spell Models

As Ian opened the book in front of him, he saw dense arcane letters written all over the four pages, where each page recorded a blood craft, as the book cover suggested, with brief information at the side. 

[Sanguine Harvest: A ritual to extract vitality from living beings during the lunar apex.] 

[The Bleeding Circle: A summoning ritual that consumes your lifespan to summon a demon.] 

[Bloodforged Contract: A method of binding a subordinate contract with a demon or blood spirit.] 

[Crimson Vitalis: A potion production method using rare or unique bloodlines that can increase longevity.] 

"No wonder!"

All the methods recorded inside were related to sacrificing blood to gain something. However, he did give more attention to Bloodforged Contract, though. 

'I can make a subordinate contract with a demon using this method?'
