Demonic & Devilish Offspring

[Dragon_Man_Of_Lore]

Can Demons and Devils mate? I had an idea of a union between a Balor and a Pit Fiend. My DM asked for my help in coming up with new monsters for a quest hes setting up, and I thought the two might be a good idea

In one of the 3.0e official module (adventure path), you can find a half-demon/half-devil. So yes, it seems to be possible, though being very rare.

Okay, thanks
