[RPG] Do all creatures have souls


The term "soul", despite being widely used, isn't well defined in 5e. Do all living creatures have souls, or having a soul is a characteristic of specific types of creatures?

The only hint I've found so far was from the Mordenkainen's Tome of Foes:

A nabassu can eat the soul of a creature it has killed within the last hour, provided that creature is neither a construct nor an undead.

This implies constructs and undead either do not have souls, or have a specific kind of "unedible" soul.

Best Answer

All living creatures appear to have a soul.

According to Dungeon Master's Guide p.24, "Bringing Back the Dead":

When a creature dies, its soul departs its body, leaves the Material Plane, travels through the Astral Plane, and goes to abide on the plane where the creature's deity resides. If the creature didn't worship a deity, its soul departs to the plane corresponding to its alignment.

This strongly suggests that all living creatures, at least, have a soul.

It's more ambiguous for non-living creatures, at least in 5e lore. Undead are the only creature type who cannot be raised with raise dead, a spell which restores the soul to its body. However, as mentioned in Does an intelligent undead have a soul in 5e D&D?, it varies by type of undead whether they have souls.
