Bonus Based on Weapon Type

If anyone can help, im looking for a script that allows an actor to receive a bonus when using a specific weapon type. Ideally a feature, a passive skill or a value that i can be given to the Actor that gives him a bonus when using that type of weapon. For instance when Simon reaches Lvl 5 and he wants to become proficient in Swords and work towards becoming a blade master, so he receives a 5 Atk bonus when using any sword type weapon. Later when he reaches lvl 10 he receives another bonus and so on so forth. I've looked everywhere but have not found anything like that. can anyone help? or maybe write a script for that?

I can't help with making or finding it, but perhaps some clarification would help the ones who can?

Do you mean to allow the player to choose a proficiency at certain stages in the game? (Such as when they reach certain levels?)

Or would these be assigned by default according to the level of the player?

Ideally I would like to have the player choose a proficiency once they reach a certain lvl, swords man expertise, bowman, etc. the bonus would increase either as they lvl up or once they reach a new lvl at it.

Not trying to be difficult, I just know there are many scripts with slight variances so I'm just trying to clarify exactly what you want it to do.
I should have included these questions before as well, but...

So, I am assuming that there are new proficiencies obtained every few levels.

Do these get added on in addition to the previously gained one(s), or do they replace it?

If they replace it, do you keep the bonuses already gained in the old one or does that reset?

Are there proficiency levels which increase the bonus, is the bonus a static percentage, or a static amount?

So what your saying is levels for weapons?? so the more a character uses a weapon the better the are at using that weapon and can level up their skill in it so when they use that particular weapon they get bonuses, but only when they use that particular type of weapon?

so your characters can use any weapon they want but get better the more they use them?
