Soul Bind

Soul Bind
Ritual Rank 11 [Binding]
Prerequisites: Eldritch Rank 10
Potency: 55
Components: Magic Essence [Rare, Value: 20 gp]
Focus: A black sapphire [Rare, Value: 1,000gp per target's level]
Cost: 1 Karma, 5 Stamina Burn
Cast Time: 1 phase
Target: One dead creature
Effect: You draw a quick binding symbol over the target's heart, pressing the gem to it. Your brief incantation causes the target's soul to bind to the gem, preventing it from moving on to the next life. The creature cannot have been dead for longer than 1 phase before you begin the incantation, or the ritual fails. A soul bound in this way cannot be returned to its body, preventing Clone, Raise Dead, Revive, Resurrection, Miracle, Limited Wish, Wish, and similar abilities from succeeding.

The more dangerous and skilled the target, the more valuable the gem needed to trap them (i.e. the gem must be worth at least 1000gp per level obtained by the target). If the gem is not valuable enough for the target, the gem shatters and the ritual fails.
