Voice of the City
For some, the ability to make oneself understood in the midst of any culture is of far greater value than the ability to influence the beasts of the wild.
Class: Druid, ranger, or spirit shaman.
Level: 1st.
Replaces: If you select this class feature, you do not gain wild empathy.
Benefit: Through a combination of body language, tone, and expression, the voice of the city can make herself understood by those who do not speak her language, and she can interpret their meaning the same way. Simple concepts that can be conveyed in a few words (such as "Help!" or "Drop your weapon!") can be conveyed automatically. More complex concepts require her to make a roll: d20 + her class level + either her Wisdom modifier (if trying to understand someone else) or Charisma modifier (if trying to make someone else understand her). Roll each only once per conversation. If she fails, she cannot try to communicate with that specific individual via this ability until she has gained a level. (Thus, it is possible, if she succeeds in one roll but fails in the other, to hold a conversation where she can understand the other speaker but he cannot understand you, or vice-versa.)
The DC of the roll depends on creature type and how closely the individual's language is related to any of her own. The ability works most effectively with other humanoids. In this case, if the individual's language uses the same alphabet as any language she knows, the DC is 20. If it does not, the DC is 30. (See Speak Language, PH 82, for this information.)
The above DCs increase by 5 if the speaker is a fey, giant, or monstrous humanoid; they increase by 10 if the speaker is an elemental. If the other individual is of any other creature type, she cannot communicate via this ability.
If the speaker is deliberately trying to make himself understood, the voice of the city gains a +2 circumstance bonus on this roll. If she is attempting to interpret his speech from outside normal conversational distance (such as eavesdropping), she takes a -4 penalty on this roll.
In addition, she gains Speak Language as a class skill.
