What happens in the end of an encounter when you are unconscious with no healing surges ? My understanding is that you regain conscious with 1 HP. Is that correct ?
No thats incorrect. The only time you regain 1 hit point is if receive healing while having no healing surge.It depends if stabilized or not.An unstabilized character will make a death saving throw every 6 seconds.A stabilized character who receives no healing regain hit points after an extended rest.A stabilized character who still have healing surges could spend as many as he wish after a short rest.RC 261 Healing The Dying: When an adventurer is dying, any healing restores him or her to at least 1 hit point. If someone has stabilized the character using the Heal skill but he or she receives no healing, he or she receives hit points after an extended rest.
