After a particularly intense Pathfinder session with my buddies, my character had to go through a trial by ordeal where he was bit by a venomous snake. He succeeded (for some definition of succeeding): he didn't die, and was cleared of all charges, but was left with a Constitution score of 2.
We play in a low-magic setting and we have house rules for recovering ability points. In the meantime, however, I would like to know what are the consequences of the lowered score.
The obvious part is that my max HP and Fortitude checks took a dramatic drop. Actions like running are now also basically impossible. We're good on the technical side, but how should my roleplay be affected? For instance, at a score of 2, I consider that my character is bedridden and barely able to hold a conversation. However, I'm having a difficult time deciding on the limits of this.
Provided that the score eventually goes up, at which point should I be able to walk again? Concentrate enough for a lengthy conversation? Are there guidelines on this?
