Are we going to go so far as to make it possible for PC's to die from disease as well, should one of their attributes be lowered to 0 ever, as standard D&D rules dictate. If so, would this also invoke a chance of soul strand loss? Might we also have diseases that have a chance of spreading from PC to PC via proximity? I mean if we're going hard core, after all, why not? While one part of me says, "Yes! Great idea, make diseases mean something." The other part of me says, "On the other hand, this will make starting out that much harder for new, low-level PC's who are the most commonly afflicted with diseases because of their lower Fortitude saves and lack of Fortitude/Constitution boosting gear available at their level, or within their monetary means." On the discussion of Curses, those should be harder to get rid of, and I support the idea of needing someone to cast a Remove Curse spell on a PC to remove the curse, be it another PC, or an NPC temple healer.

On a similar vein, make the effects of a Bestow Curse spell impossible to dispel without Remove Curse or a trip to a temple healer, rather than a simple night's rest.
The one idea about having a 25% chance to remove the curse/disease at a safe rest area will just mean people will keep resting till they get it removed so not sure that will work as you visioned it working.
More generally, my proposal would be to substantially increase the Heal DC required to remove disease, and make sleeping at a safe rest area only have an x% (25%) chance of removing the disease, (and in so doing, set a variable on the PC to prevent them sleeping repeatedly in the hopes of rolling a 75 or better).
Adds power to the cleric class:Cleric is already one of the most powerful classes in NwN, there is no need to add more to their template even with the new bandages and healing potions they still have a high use. Some spells will always been more useful than others, just like feats and skills. Trying to change Layo to make all of them useful would be the screw with no end
