You are deadly when delivering your master's magic.

Prerequisites: Deliver touch spells ability, familiar.

Benefit: When delivering a touch spell for your master, the critical threat range of your touch attack is doubled. This feat does not stack with Improved Critical or other effects that increase critical threat range.

Special: Feats that are meant for familiars can be switched out for a familiar's default feats (as listed in the familiar's statistics) if the familiar meets the prerequisites. Such feat replacements must be made when the PC first acquires a new familiar, and like all new feats from supplemental sources the new feats should be approved by the GM before being integrated into play.
