Greater Raise Dead
Upon completion of the ritual, the target creature suffers a permanent loss of 1 Resolve and 1 Stamina, but is alive and at full health (see Raising the Dead). In order for this ritual to be effective it must be performed within [10 years per Ritual Casting Rank] of the creature’s death. The body needs to have at least the majority of the bones present for the ritual to work. All injuries sustained by the target are healed, and any Traits resulting from injuries may be removed at the target's choice.
The more powerful the target was in life, the greater the value of the gem needed to revive them (i.e. the gem must be worth at least [200 x ( target's level)² gp]). Research or divination may be necessary to determine the necessary gem value. If the gem is not valuable enough for the target, at the conclusion of the ritual it turns black, crumbles to ash, and the ritual fails.
