The Boss' card not dropping?

The boss is what people call "Grampa." Male boss is the nooby boss running around outside. Cards will not drop if there is a huge level difference between you and the foe. I think the treshold is somewhere 15-20 levels below the monster, give or take.

This is only true for mobs ABOVE you. If the mob is 15+ levels above you then it will not drop a card for you.

EDIT: Sorry, you are saying the same thing... It's just not immediately clear. So, yeah, CarrionCrow +1
