You have a rough understanding of demons' guttural babble.

Benefit You add Abyssal to your list of languages known, though you take a –2 penalty on Diplomacy, Intimidate, and Bluff checks made while speaking Abyssal, as well as a –2 penalty on Linguistics checks made to read Abyssal text. If you gain Abyssal as a language again at a later time (such as by taking a rank in Linguistics and selecting Abyssal as a learned language), these skill check penalties become +2 trait bonuses instead.
