I looked up Child of Set at rpgnow, and found this item from Misfit Studios, but it's $1.00, so if this is what you're posting about it's pretty cheap, but it isn't free. :wink: This entry is for OGL Barbarian system. Anyway, this is the link I got:
It was indeed free yesterday, as René said, as were the other three samplers from Misfit (Deep Wilder, Hawkeye, Sea Devil). Lucky me, I managed to snag them before the price went up ....although $0,75 is pretty close to free.
