Existe um total de 21 Pyromancias espalhadas pelo jogo, sendo que, algumas têm de ser coletadas, já outras têm de ser compradas a NPCs específicos. Não é necessário usar as mesmas, apenas é necessário ter as Pyromancias em seu inventário de magias. P.S: Relembro que a maioria das Pyromancias tem mais do que uma localização possível, logo não se esqueça de conferir o link abaixo.
Aqui fica a lista da localização possível, em português, de todas as Pyromancias:
