Psycristals and Familiars were pretty similar in 3E already.Wow, those quirks are really fun!
They remind me a bit of the 3E psicrystals which granted a bonus to their master based on their personality. Those were also a good source for a bit of roleplaying.
Well I'm pretty excited to see the official rules
I'm just disappointed that the familiar rules didn't include options for inanimate objects with intelligence, like a talking sword or hat.
I suppose it's easy enough to houserule though.
