When you cast find familiar, you can choose for your
familiar to be a gen instead of one of the normal
options. Statistics on the different types of gens in
their true forms appear at the end of this archetype
description. When your gen familiar is first
summoned, it gains temporary hit points equal to
your proficiency bonus + your Charisma modifier.
If you have the Elemental Potentate otherworldly
patron, this is your gen servant manifesting its true physical body, so it must be a gen of the associated
type for the element you chose for your Elemental
Patron feature. Such a gen familiar grants all the
same benefits it would in its incorporeal form, as
long as you are able to communicate with it
telepathically. While your gen familiar is dismissed,
or if it has been reduced to 0 hit points and you have
not summoned it again since, your gen servant can
still appear in its incorporeal form.
