From publisher blurb: Read Magic: Vigor adapts incremental healing spells from the third edition ofthe well known roleplaying system. It balances them against burst healing spells like cure light wounds and then creates other related incremental healing and damaging spells. This also seeks to change and adapt some existing iterations of the spell within the Pathfinder ruleset. Namely infernal healing and celestial healing from Paizo Publishing and vigor of the grave from Rogue Genius Games.
