Some Demons may only be acquired through Deathstone Fusions. This guide will tell you what Deathstones are, how to get them, how they're used as well as all the different Demons you can get through Deathstone Fusion in Shin Megami Tensei III HD Remaster (SMT Nocturne) for the Switch, PS4, and Steam!

What Are Deathstones?

Deathstones are cursed stones that call upon forces of death. Depending on the phase of the moon, and your progress in the game, Deathstones may alter the outcome of fusions and allow you to unlock members of the Fiend race instead.

How to Get Deathstones?

Obtained in the Kalpa Dungeons

Deathstones are found throughout the Kalpa Dungeons. They're often contained in Cache Cubes found after clearing the major puzzles of a Kalpa.

Bought in the Third Kalpa Dungeon

In the Third Kalpa Dungeon, a Shady Broker can be found in the Neutral-aligned room of the Luck Path. You'll need at least 14 Luck to unlock his room, but when you do, he will sell you unlimited Deathstones for 100,000 Macca each.

How to Use Deathstones?

As long as you have Deathstones in your inventory, they will affect your fusions in the Cathedral of Shadows. You'll know that a fusion will be affected by a deathstone if the fusion chart presents a Skull instead of the usual circles or triangles.

Keep in mind that a Deathstone is used up upon fusion. This means that you'll have to be sure of your fusion since you won't be able to retry it.
