"Also, when raising the dead, a process must be taken to summon the “soul” back to the body, and just as in the case of “call ghost (p.101)”, if the soul is still in the mortal world, then it is easy to summon, but calling a soul back from the netherworld requires the cooperation of “Hel”, the goddess of life and death. In other words, the fresher the corpse, and the deeper the regrets of the deceased, the easier it will be to raise them. The difficulty of raise is also dependent upon the race and sex of the person. Generally, humans are the easiest to raise because they are more readily susceptible to erosion by mamono mana, and then it goes “dwarf (Encyclopedia I -p.100)”, “elf (Encyclopedia I – p.96)”, monster, and god, in order of increasing difficulty.
