True Imprisonment by Eternal Chains

For 2 turns the caster concentrates on the spell, if not interrupted the caster enters a trance, remaining stationary and constantly reciting a mantra. The caster gains a magical defense with +3 passive effect to all saving throws during the mantra recitation.

The mantra holds until the caster is rendered silent, unconscious or dead or the target HP hits 0.

Ethereal chains manifest around the caster and the target, dealing 10d10 irresistible non-lethal damage to the target every turn (including enemies and other combatants). The target has all movement enhancements and modifiers (ex.flying) nullified and movement halved. If the target dies under this effect, they are sealed instead and the caster creates Key(s) to the seal. The seal can only be lifted by divine intervention or the Key(s) defined by the caster. The keys must be items of some significance or the seal will backfire sealing the caster instead.

If the target succeeds in a DC30 saving throw (highest stat of target) the damage is reduced by 70% and movement modifiers (ex.flying) are not nullified

If the caster is interrupted during the mantra by Silence, Unconscious or Dead, statuses the spell will backfire drawing in the life of anything within 15ft radius of the caster and sealing the casters soul permanently. The caster can never be resurrected, and every living being within 15ft radius is dead.
