In an upcoming campaign, one of the players has an idea for a party healer. The idea in a nutshell is that they come from a world where there are no gods that grant divine healing. Undead dominate the world and the gods whose domains had healing in them were either driven off or killed.
So to circumvent this limitation the player is proposing playing a LN healer who gains the ability to cast healing spells by consuming the vitality of dead flesh. Lesser healing spells are powered by eating animals parts, greater healing requires the consumption of meat from humanoids.
Since the character is LN, they will not be actively seeking slay animals and humanoids for consumption. But given the opportunity, they will consume the meat to support the rest of the group.
Not wishing to delve too deeply in the limitations of the D&D alignment system... Does this concept work OK in your opinion with a LN outlook/alignment?
