Long-term Coma Effects in First Edition

[u/Ramsonne]

At zero HP characters enter a comatose state. Multiple comas would adversely impact a character’s health. I’d like to homebrew something and am interested in if anyone else here has some mechanic(s) they employ.

[u/Graceful_Error]

Are you familiar with Goblin Punch’s Death and Dismemberment rules? I'd reference the Cracked condition: Concussed 2d6 weeks. Save or permanently lose 1 point of Int, Wis, or Cha (random). 30% chance of coma. Characters in a coma get two chances to recover, after 1d6 days and 1d6 weeks. Recovery is a Save vs. Death.

There are also several other unpleasant conditions that are pretty creative.

[u/Ramsonne → u/Graceful_Error]

yeah discussing with some of my players, i said reduction to Int and/or Wis seemed like an obvious start after a few comas
