For the next few days, Rino found himself pouring over papers and drafting countless spells. Not everything should be added to the grimoire. Some of his best magic circles were also useless in this world because Rino realised the town wasn't built with enough magic circuits for complex spells. 

The lamia leather grimoire had limited pages and while Rino could rebind a grimoire to add pages, carrying such a thick tome around was inconvenient. In his previous life, Rino did not use grimoires. Instead, he stitched spells into his clothes and wore many layers because of it. Some of his more elaborate accessories were engraved with spells that gave him conveniences such as flight, dark vision and underwater breathing.
