Death Curse
Was activated 20 days ago.
Anyone who has previously been brought back from the dead begins to waste away.
Their hit point max is reduced by 20, and decreases by 1 every midnight. Once at 0 hit points, they die.
The soul of anyone who dies is trapped in the Soulmonger. An atropal eats the souls. Once it has enough, it will become an evil god.
Liches can't trap souls in their phylacteries.
The spells revivify, raise dead, resurrection, and true resurrection do not work.
The Soulmonger does not affect pre-existing ghosts and spirits. Speak with dead and other spells like it still work normally.
When a soul is trapped in the Soulmonger, roll a d20 each day. On a roll of 1, the soul is destroyed.
Spells like commune and divination can determine if a soul ha been destroyed yet.
The DM decides when the atropal has enough souls to become a guide. It could be months or years.
Meatgrinder Mode: If you want, you can say that the Soulmonger make it so that you only pass a death save on a roll of 15+ instead of 10+.
If a Character Dies: They can't be raised. They need to use a new character.
