Distance can’t sever the bond between you and your familiar.
Prerequisites(s): Intelligence 13, must have a familiar.
Benefit(s): You retain your empathic link to your familiar regardless of distance, though lead blocks the link at distances greater than 1 mile (similar to the way lead blocks detect magic effects).
