expand_less The famine spirit’s speech calls out to those who share his hunger. At 1st level, this ability functions as wild empathy, except it can be used only on undead with an Intelligence of 2 or less (including mindless undead). Undead typically have a starting attitude of hostile.
At 5th level, undead with an Intelligence of 2 or less do not attack you unless you move within 15 ft. of them or attack them, and you can use parched tongue on undead regardless of their Intelligence.
At 11th level, you can use parched tongue as a standard action against undead with an Intelligence of 2 or less.
At 15th level, undead with an Intelligence score of 2 or less do not notice you unless you attack them or target them with parched tongue.
This alters wild empathy and replaces steal language, endless communication and boundless communication.
 
Wild Empathy:
 
A character can improve the attitude of an animal. This ability functions just like a Diplomacy check made to improve the attitude of a person. The character rolls 1d20 and adds her class level and her Charisma modifier to determine the wild empathy check result.
The typical domestic animal has a starting attitude of indifferent, while wild animals are usually unfriendly.
To use wild empathy, the druid and the animal must be able to study each other, which means that they must be within 30 feet of one another under normal conditions. Generally, influencing an animal in this way takes 1 minute but, as with influencing people, it might take more or less time.
A character can also use this ability to influence a magical beast with an Intelligence score of 1 or 2, but she takes a -4 penalty on the check.
