This idea came to me when I was looking through skills for a new character, and noticed something... who the heck ever really uses Linguistics? Yeah, it's handy for learning languages, but... do you really use it that often?
That's when an idea sprung into my mind; why not have a class or character build designed around making Linguistics functional!
Now, I already had a look at the 3.5 class Truenamer, and people seem to be either of the opinion that it's broken in a good way, or broken in a bad one. Having never used it, I can't say. But it does open up the gate for some intriguing ideas for this class.
The general concept of an Incantionist is they harness the spoken word to call on magical powers. I suppose this would fit a bit more into Wizard than Sorcerer, but I can see it working for both. Sort of like a Bard, but less musical and more arcane. The idea is when you utter certain phrases (possibly of some ancient language of the gods), things around you change. You can use it for offense, defense, or support.
Spells would have a DC of 10 + 1/2 your Linguistics skill, learning a new spell demands rolls using Lingusitics, and uttering a phrase using a language already known by your target ups the DC, or gives you some sort of bonus.
I dunno. Just something to give Linguistics a bit more use. Because I like to think outside the box obsessively.
Then why not a bard base?
I have used linguistics in various games a decent bit. That is the code-cracking and lost-language-translating skill, right?
