This spell is a part of the Time Ripple spell chain and is found in the Time Ripple rune stone.
The posteramancer does not deal in healing just as they do not deal in revival, or even in damaging or death. They deal only in time, and in the posteramancer's own affinity it is in the time that has yet to come. They see the web of future timelines, of events yet materialized that could be should certain events play out. When casting Future Renewal, the posteramancer isn't healing, not in the traditional sense. They are simply choosing from a timeline where the healing took place and are bringing that time into the present for the target. Thus the Vitality that was lost is restored by some future event, and because of the time that passed so too has the target's Power returned. It is a recovery that could have always happened, one of the many timelines Fate has written, and through the power of Fate, it is simply made a reality.
When this spell is cast the posteramancer reaches through Fate into that already-written recovery and draws it forward into the present. The target's Vitality and Power are restored by 1d20. This is not because the posteramancer healed them, but because the healing was always coming and has simply arrived ahead of schedule. The wound that was there a moment ago belongs to a future that has already been skipped past. The posteramancer mentions none of this. They simply nod, already knowing the target was going to be fine.
