'Heh! No need to worry about the missing scroll. I can always get it from Malcolm.'
Eren thought to himself as he continued to read the book's description. Owning this book had cut down the cost of the spirit beast spell in half for Eren.
Eren was very interested in the spell after he found out what it could do. It seemed to be so much more than just summoning a beast to fight with you. For starters, if there was sufficient compatibility between the beast and the ranker, the latter would be able to gain the former's inherent spells for themselves.
Having a spirit beast was akin to having a permanent partner one could count on. The inherited spells from the spirit beast were a bonus. In addition, these spells would be part of the ranker's existence. As such, they would get upgraded automatically to the next tier if and when the ranker and their spirit beasts broke into the next rank.
