lemme see if i can make an example of the sorts of stuff that seems promising from what i'm seeing suggested:
Billy: hello hagable
Hagable Lechter: what do you want? I'm busy!
Billy: Hagable give me a quest
Hagable Lechter: don't even ASK me about quests
Billy: Hagable about quests
You Got A Curse.
Hagable Lechter:
I warned you, nolthrir not to ask such things
Now you will see what this misdeed brings
(Rhymes & stuff including hints for who to cure you like
"no doctor or shaman will cleanse you of this pox
your body its own prison, that only faith unlocks"
suggesting perhaps a cure relating to the temple... religious, faith... any event: hints...)
and the curse would be something like
Not healing naturally (or possibly at all)
Being unable to equip
Being transmogrified (i'm guessing into something immobile would be the most likely direction for this... i know i seen someone turned into a stuck rogue temporarily)
Being unable to get npcs to talk to you or being restricted in travels... (i think you'd still need to be able to talk to ones in the quest... unless (as i assumed for immobile) it could be cured by an item, thus making you seek the help of other player characters... restricted in travel, same idea but less likely until world were expanded, seeing as there is so little you can reach if banned from hydlaa [you can go where you are, where road leads or dr] which could work if the cure was in dr)
my opinon: Player curses? nah. roleplay em if you want em, but i don't see it being implemented if its anything like the above suggested curses-- maybe if it were just something like reduce charisma till they cure it,
