Deliver Touch Spells (Su)
Source: Advanced Player's Guide, p. 69
If a witch is 3rd level or higher, her familiar can deliver touch spells or hexes for her. If the witch and the familiar are in contact at the time the witch casts a touch spell, she can designate her familiar as the “toucher.” The familiar can then deliver the touch spell just as the witch would. As usual, if the witch casts another spell before the touch is delivered, the touch spell dissipates. If the witch activates a hex, her familiar can be used to make the touch. She does not have to be in contact with the familiar to use this ability.
New Familiars In addition to the familiars presented in the Pathfinder RPG Core Rulebook, witches might select any of the following animals as their familiar. Sorcerers and wizards might also adopt these new familiars, utilizing the same rules as for any other familiar.
These familiars make use of statistics presented in the Pathfinder RPG Bestiary (on the noted pages), specifically the house centipede (43), king crab (50), greensting scorpion (242), fox (dog with the young template, 87), octopus (octopus with the young template, 219), and scarlet spider (258).
