I have been thinking about how to make a illiterate charactor trait. Here is my first draft (... or accurately my second but don't mind that)
Character Trait: Illiterate
The character comes from a illiterate background and isn’t able read or write.
An illiterate character cannot trigger spells, magic traps or cures that are triggered by reading. A illiterate character gains a +2 bonus to saving throws against magic that involves runes, symbols or signs.
What do you think? Comments or suggestions on how to improve the trait is welcome.
