*Re-post from Obsidian General*
I think an interesting concept for the spiders would be incorporating webs! For example, if you get knocked out by a spider, they would start wrapping your character up in a web. Your friends would have an opportunity to come rescue you and/or there could be a "wiggle" button for the chance to escape on your own. If you don't get rescued or escape in time, then your character dies after a certain period of time. The spiders in general are a bit overpowered, especially in the early game, so if there was an opportunity to fight them a bit and escape, I thought it might be a cool concept. Just an idea!
