Okay, so I found this in the book.
"A 'skill' is a particular kind of knowledge; for instance, judo, physics, auto mechanics, or a death spell. Every skill is separate, though some skills help you to learn others. Just as in real life, you start your career with some skills and can learn more if you spend time training.
A number called 'skill level' measures your ability with each of your skills: the higher the number, the greater your skill. For instance, 'Shortsword-17' means a skill level of 17 with the shortsword."
and
"Difficulty Level
Some fields demand more study and practice than others. Four 'difficulty levels' to rate the effort required to learn and improve a skill. The more difficult the skill, the more points you must spend to buy it at a given skill level."
So going with that, a Pistol skill is an Easy skill. And takes 1 Point to learn per 1 level.
A Medium arms is an Average skill, and takes 2 points to learn per 1 level.
Explosive arms are Hard, and takes 3 points to learn per 1 level.
And if you have 4 points to spare, you could get a level of Bullet-time dodge, which is a 'Very hard' skill and dodge motherfuckin' bullets without using cover.
Vigil already spent time and points on bullet-dodging, it'll be good to see your Character training to get those skills that you've brought in-game.
So when you have 9 points, you of course could go pure Pistol and be a really good with the thing at level 9.
Or you can take 3 levels in explosive arms and shoot grenade launchers with trained hands instead.
Or 4 levels of Medium arms and make any regular military rifleman proud.
I think this way leveling easy skills will be rather painless, while harder skills are still able to get really, Really good at without the skill cost ramping up too high while still being a challenge to get up there.
Plus without the cost price rising up, you can either choose to focus on a group of skills or spread out even more and have a few easy skills to go along.
And not to mention how easy it would be to implement new skills! It'd just be giving me a name, and I say if it's an Easy skill, an Average skill, a Hard skill or a Very hard skill.
What do you guys think?
Also we're so putting this in the new book to make it clear and easy to understand.
