With the Reliable Enhancement, a successful casting is enough to raise the dead, with the only caveat being the amount of damage the corpse has sustained.

If the subject was killed through massive damage, additional FP beyond the spell's base requirements may be required to heal them above -5xHP, as any excess damage will cause the subject to die again. If the subject's body was destroyed via enough damage to drop them to -10xHP, you cannot bring them back. However, you could collect a sample of the remains (if any) to clone them, but that's another spell entirely.

Due to the Faith Healing Enhancement, this spell can only be used by those who do so in a religious manner. Other spell casters have their own methods. When other methods fail, some wizards take Frankenstein's approach, building a Flesh Golem from the left-overs. This is almost always uniformly looked down upon as dark necromancy, regardless of intent.
