I like the narrative style in the instructions. Also I that cockatrice are actually just chickens.
Good job.
if i'm being fair to my Monstrous Manual back home, i think a cockatrice is more accurately a lizard, rooster, bat hybrid or 2-legged dragon with a chicken head. i have no idea the origins of the (potentially iconic?) snake-head-chicken-head thing i am presenting here. i mean, that's what showed up when i google image searched cockatrice but WHY? d&d mandala effect?
