Hello, I think i got a cool idea: There is a normal Minecraft world, but it isnt as normal as any other world. That's because there is running a virus that can kill you. The virus can spread if you come too close to somebody. You can get the virus by somebody else, or walking into an infected area. When you're infected you will see a message, and loosing health slow (that can't be fixed with food). You need somebody that is assignd that can help you. The user that can help you must be protected with Chainmail so they won't get infected. The team must clear the arena, and stop the virus by clearing the area with a splash health potion. (The virus can must be a person or a block (not an air block!). Looks like a cool idea right?
I don't see what you mean by clear the arena of viruses, what would be on the blocks to say "THIS BLOCK IS INFECTED."?
The block that is infected can turn into Mossy Cobble Stone! i would love to make this but have no drive to. (sorry)
If someone is going to do this I would highly recommend changing the word "virus" to something less freak-everyone-out-ish, if you know what I mean.
