Arachnocraft is a new mod made to add lots of new spider-themed items, mobs, and even a new dimension. It centers about the journey to enter the Spider's Den, a dimension that is comprised of a giant cave where you can find a overabundance of hostile mobs, along with some precious ores and rare structures with epic loot.
In the future: ride able spiders, drow elf civilizations, new spider breeds, arachnomancy, and even a web cannon!

Nice mod, but I couldn't figure out how to light the portal for the spider's den, until I found the Unobtainakey which, obviously, is unobtainable. Also, I feel like the spider's den is a bit blank, your probably working on this but I just wanted to let you know. Other than that, it's great!
One of my favourite mods!
