Calantar's Cave (7-10)
Quest Giver: Mr Blisterfoot, located in Calantar's Road, Blisterfoot Inn
The journal entries are blank when accepting the quest or fulfilling its completion requirement, such as killing the boss of QA.
It doesn't have to be numbers, I just thought of it as the simplest way that (probably) requires least amount of effort to implement and to get the topic started, considering that there are multiple possible scripts to learn and having interesting prompts for them would be be way more welcomed as well, but would also warrant more effort. I would be more than satisfied with any kind of implementation that makes sense :)
Basically, I am suggesting a QOL feature that gives a Player Character ability to see how far (or little) they have progressed with learning a script from the placeables, to encourage exploration and to have a vague idea if they're moving in a right direction. Akin to a dialogue in the Crafting Menu that shows information just like Tradeskill Journal, something like Netherese 7/31, Elven 3/7, etc..
Because as it stands now, I have no idea to know if my character is completely clueless about a language, or is on a verge of breakthrough to have full fluency with it, for example.
It is a basic NwN simple weapon, but it also requires a feat investment in the form of rapid reload so you don't shoot only once per round. I think that a good way to make them better is to give them better massive critical rolls/dmg boosts than the bows, since it won't make them better than bows on average, but when the stars align, when a crossbow counts in the battle, it counts.
