Languages are designated as follows:
The first is the quality of the language in speech. That ranges from 1-4
1. Important phrases only
2. Can speak the language normally (Most people never go beyond this)
3. Fluent (Like an upper class person or scholar)
+1 - It takes 1 extra point in a language at any level to hide an accent. This can also be accomplished with a Bluff vs Perception roll.
Languages are learned either over time as the GM allows or as follows:
> 16 intelligence at level 5 OR at level 10 regardless +1 language
> 22 intelligence at level 10 +1 language
> 16 charisma at level 5 +1 language
> 22 charisma at level 10 OR at level 20 regardless +1 language
Linguist feat - raise an existing language you know +1 fluency
AND learn a new language at fluency 1
(It may be taken multiple times)
A person with a 16 int gets their level 10 extra language early. They do not get another one at 10th.
A person with a 22 cha gets their level 20 language early. They do not get another one at 20th.
