I have found my holy grail of useful DM Resources. This Party Tracker is by far my most used and most loved resource.
Created by /u/boobonk this party tracker is an editable PDF with a style that matches the character sheets.

DM Resources: Herbalism and Alchemy
This fan-made supplement by Dalagrath is not only beautifully laid out it is also fantastically well documented.
My players have been asking about crafting their own potions and poisons for a while and the books don’t give much guidance on this topic.
The Find Familiar Spell Packet
Two of my players are wizards and have a tendency to change their familiar to suit the situation quite often. I found looking up stats in the monster manual and rereading the spells description time-consuming and worst of all it brought everyone out of the game.
To alleviate this I put together a printable packet for my players on the spell and all possible forms the familiar could take.
Meta: DM Resources Page
I just added a DM resources page! I have listed out and linked to a multitude of resources I use regularly. I have plans of adding additional resources as I find them as well as uploading some of the resources I made for myself.
If you think I’ve missed an amazing resource let me know in the comments!
