In editions past, Drow are pretty well known for using poison. It's just "who they are". While playing some 5e and creating a side mission I thought, "I will add some Drow since they use (traditionally) sleep poison to make for an interesting fight."
Now onto the real question. Why don't Drow in 5e, from the lowest pleb to the highest priestess, use poison. On page 126 of the Monster Manual they go into detail about the Drow and their abilities, but no poison? Why is this? Was there any reason for this, or was it just an oversight?
