Ferret said:I thought in Tome and Blood that it says the familiar remains all of its powers, but is free. It doesn't resent the party but if it sees no reason to stay it won't.
If a master dies and the familiar survives, part of the master lives on in the familiar. It loses any extra hit points and skills it gained from the master but retains most of its familiar abilities. It is treated as having a master two levels lower (but never below 1st level). If the master is later brought back from the dead, the bond is reestablished, and the familiar gaines whatever abilities go along with the master's new level.
