Say I take the spell Telekinesis. Then I take the 3rd party feat Familiar Concentration. I cast the spell Telekinesis and do a combat maneuver. Then I hand over the concentration to my familiar. What happens next?
Which one of us is directing the spell? Whose stats do I use for the CMB?
My intention is to continue using Telekinesis through my familiar while continuing to cast other spells / do other things. Does this work?
There is a different forum for third party questions.
I would assume that the spell still counts as cast by the familiar master. The familiar is only fulfilling the concentration.
