I came up with an idea, but other players can supplement it or fix it, i not be interested in spider health and speed, i just came up with what kind of behavior and abilities he has.
I'm sorry, but that's not how this forum works. It's your suggestion; while we can perhaps suggest possible alterations to make it better, you must be the one to fill in all of the information.
If you want to collaborate, send a PM with to one of the more established suggestion forum-goers asking if they would like to help you with an idea. We do not have a dedicated place to create suggestions with others.
I cannot on good faith support an incomplete suggestion.
