In D&D3.5, I'm playing a warforged crusader who has recently taken a lot of CON damage. Normally this wouldn't be a problem, but I have the Improved Fortification feat which makes him immune to any spell of the 'healing' subtype. We're also not playing Eberron and warforged are very rare in the setting, and 'repair' spells are rare-to-non-existent.
Does the fact that warforged don't heal hitpoints naturally extend to ability damage? If so, is there any other way of restoring ability damage besides throwing myself on the mercy of the DMs?
