A while back, there was some discussion about the cat agathion familiar's lay on hands ability DC scaling with level, since the agathion ability scales with hit die, and "for the purpose of effects related to number of Hit Dice, use the master's character level or the familiar's normal HD total, whichever is higher." That was resolved in a kind of in-between compromise way.
My question is about the poison for other familiars; poison DC is usually 10+1/2 racial hit dice+Con modifier. Would this scale? In the other threads I've found, there's an implication that it does, but I'm looking for something more official, or barring that, a consensus here.
(My scorpion just realised that the guys the monk's grappling make excellent victims... but nobody's going to fail a DC 10 fort save.)
