This is a great group for students with super special scary ideas about new monsters for D&D. We will use the D&D 5E rules (of course) but we will let our imaginations wander as we create the ultimate monsters for the "world's greatest role playing game"!

Do not limit yourself to only scary monsters! There are plenty of awesome ideas which can be cute and friendly familiars and/or companions as well. You might even have fantastic ideas about sidekicks and non-player characters (NPCs) that you would like to share. Your imagination is the only limit to the absolutely wild and creative creatures we can share with each other. 

When creating your version of a monster it would be best to have a picture/drawing of your monstrosity. This can also be a written description of how you might change or alter these creatures if you do not wish to draw. OR you could make a clay model of your monster or familiar. Also provide a written description of the monster's special attributes as well as an imaginary scenario when the adventures encounter the beastie! This will help Dungeon Masters if they want to use your creation in the adventures with their players. 

As per the Dungeon Master's Guide there are some rules we must stick to to make it official. It would good for everyone to also see the STATS of your creation. This can be done on-line by going to https://tetra-cube.com/dnd/dnd-statblock.html. If you need help with this let me know, it might be a little hard at first, but once you do one or two it gets easier. Then you can take a snap shot and include with your post about your new creation! Super Cool! Perhaps other DMs will use YOUR creation in their next adventure!

As moderator I will facilitate the creative process and help check the student's idea against the D&D 5E rules to make sure it ticks all the boxes. Questions that I will provide concerning monster creation: 

What noises will the monster make normally? How about when he spots the adventurers? 
What is the monster's "ecology"? What type of environment does it live in? 
How would the adventurers know that they have spotted the monster? What signs does it leave behind?
Will this monster be able to regenerate hit points like a troll? If so, how many per round?
Can this monster be reasoned with? Could the adventurers talk their way out of confrontation? 
Why is the monster that color? How does the monster see color? What color could the adventurers wear to avoid detection?
How is its sense of hearing? Does it have keen hearing? 
What inspired this monster? 
How do you envision it being used in a dungeon? Should the adventurers encounter it at the beginning or towards the end?
