Hunting low level monsters for equipment drops

These might sound like silly questions, but I jut want to be sure:

A) Are bosses affected by this [I'm assuming no but still want to check]

B) Are familiar cards affected by this? [i know for some monsters they still drop like candy [spore], but I still havnt found a big spider card on my level 200 DS with multiple drop rate multipliers]

A) No
B) No, drop rates for some familiars are just low.
