ah i remember when the nerconomcion was the best "weapon" in the game and where a run where pacific berserk ring was easily possible with it (unless a forced fight with a fire gecko happens that is the hards enemy endless mode king is easier than story mode fire gecko) so sad that there is a 5 use limit since the dev had to nerf mana farming maybe only have the 5 use limit on the mana and not the effect of the book
