The file in the official content thread has a lot of out of date data for the monsters (the drow priestess is from 3.5e I think). Attached is a 5e_Drow.dd5 file that has the updated data for the Elite Drow Warrior, Drow Priestess of Lolth, and the Yochlol all with SPELL LINKS!

I formatted the entries as close to the pre-loaded content as I could. If you would like me to post other monsters let me know what you are wanting.
