Dungeon Master Assistance

donjon.bin.sh is an online collection of random generators and other tools for pen-and-paper role-playing games. Check out all of these excellent generators. The reason for this post is to recommend their fifth edition spell list that can be accessed here:

5e Spell Sheet

You can quickly sort by class, level, which book it is in, etc. Also, if you click on the spell name you get a pop-up with the spells Casting Time, Range, Components, Duration, and (if it is in the SRD) a description. I find it easy to use and very helpful.
