On the Aifala Continent, "resurrection" is both a simple and difficult matter.
It's deemed simple because the earliest spell involving the concept of "resurrection" in the spellcasters' magic table is the 3rd Ring's "Resurrection Technique".
This means that a Priest, Paladin, and other related professions and their sub-classes, who have just reached Professional Level 5, can acquire the ability to resurrect the dead.
It seems incredibly powerful, almost a little overpowered.
But in the real world, when considering the various stringent conditions it requires, this low-level spell becomes particularly cumbersome.
Not to mention the spell's own requirements for casting materials, which are exceedingly expensive for general professionals.
The limitation that it can only resurrect creatures that have died within one minute already removes it from the beautiful essence of "resurrection", relegating it to an unpopular category.
