Hello. I think this is a really awesome thread and idea, and I wanted to contribute so... I tried my hand at statting the drider.

It's not complete because I wasn't sure what class skills and proficiencies to give it but I wanted to show what I had done, at the very least to know if I was doing any good. so, here it is.
