Linguist is a heroic tier feat available to characters with an Intelligence score of 13 or higher.

Prerequisites: Int 13

Benefits: Choose three languages. You can now speak, read, and write those languages fluently.

Special: You can take this feat more than once. Each time you select this feat, choose three new languages to learn.[PH:198][HotFL:315][HotFK:316]

Note: Although not in the official WotC rulings, many Dungeon Masters will create a house rule that doesn't allow you to learn Supernal, the language of the gods, in this way.
