1) If you fall unconscious… a death-saving throw is now a 15 or greater – do to Acererak’s (the Black rider of Badna) fighting for your soul.
2) After every long rest, you have to make a constitution or wisdom (your choice) save. Starting at DC 12. The DC will go up slowly over time. If you fail the save you lose one D6 hit point permanently. Or until the situation has been resolved.
3) We will NOT be using the “slow and natural healing” variant. It will be hard enough.
4) Once a soul becomes trapped in the Soulmonger, it’s only a matter of time before it is devoured. You can determine the status of a trapped soul at dawn on any given day by secretly rolling a d12. On a roll of 2 or higher, the soul remains trapped in the Soulmonger, at least until the next dawn. A roll of 1 indicates that the soul was devoured. A creature whose soul is devoured in this horrific manner can’t be returned to life by any means, including divine intervention.
5) Any spell that breathes life into the dead (including revivify, raise dead, resurrection, and true resurrection) automatically fails.
