I wanted to give them a try again because I only ever used them in my first run, when I thought Gale might enjoy a summoned cat. (Summoning Tara would be something!) The raven's peck is kind of useful, and at the very least any familiar is another body on the battlefield - but I most fondly remember how delighted child NPC are by the summoned cat (and by Boo) and follow it around. Not entirely useful, but very cute.
