So, I know l can have my Familiar cast a Touch spell, so l was wondering, do they concentrate on it, or do you? Like, if I'm a Pact of the Tome Warlock, with Guidance and FF, could l have my Owl Cast & Concentrate on Guidance while I'm Concentrating on Shadow Blade?
It's still you. You're just casting the spell from your Familiar's location. The limitations of Concentration are one of the details where WotC has been pretty careful to not provide bypasses for.
