Demonic possession happens all the time in most D&D/OSR style games.
I watched Evil Dead 1 and 2 today (some of my favorite movies) and realized that even if you “escape” from demonic possession, you shouldn’t leave the encounter unscathed.
If a character survives demonic possession, have them roll a d30 and consult the chart below. They are now afflicted with this condition.

| 29 | Wrath | When you kill someone you must make a Will save DC 14 or continue to attack, even friends. |
| 30 | Glee | You take pleasure in watching deplorable, despicable, and vile acts. Even when appalled you laugh and cackle gleefully. |
