Welcome to the team!
In case you don’t feel like reading the “spider web” feature, here is the TLDR: You can cast the web spell once per rest without using a spell slot. When cast in this way, it counts as non-magical.
No offence or anything, but in my eyes, witchcraft ≠ facilitating copyright infringement, so your comparison is a little flawed.
I’ve always had a lot of respect for people who paint as a hobby. I know I don’t have the patience or skill to do art, so I’m always flabbergasted by what people can make. Great work, and thanks for posting it here!
