I recently was on a server which you could buy a home in a town, and the interior design inspired me to add some more. (Some more interior design that is) I decided I would make a laptop, so I made it with an item frame, a iron pressure plate, a jukebox, 2 oak planks and a oak stair (as a chair). Inside of the item frame I decided I could put two things, either a glass pane, or a cobweb. Glass looked nicer, but I thought that the cobweb could be punny. (Searching the web )
So I decided on cobwebs... except i noticed that I've never gotten them, and that I had used shears on cobwebs before already. I thought maybe a silk touch pick would to the trick but it didn't, I then looked it up and found the ONLY WAY to get cobwebs, (in vanilla minecraft) is having Silk Touch I on shears. But you cant enchant sheers, you have to combine a book with them to enchant 'em.
I tested it on singleplayer and found it was true. The problem is, Silk Touch I is the RAREST thing to get on a book. (Technically tied with Infinity) I gave up on the idea and decided to just use glass panes.
This got me thinking, we all know that the single block which you can only get one of in the whole game of vanilla is the dragon egg, but what are the things hardest and most rare to actually obtain?
Now I know that if you enchant a lot of books, you can get silk touch in about 100-120 tries, so this is probably not the top of the list.
What about mycelium? Obviously on servers, or if you use an external program to find where biomes are, you can easily find them, or someone will likely have it. But who would waste a silk touch book on shears just to get cobwebs? That's the only thing (that I'm aware of) that you can use a silk touch shears on that makes a difference from regular sheers.
I believe in the snapshots (if not in 1.7 already) you can make circle stone cracked stone etc. And prismyrine isn't near as hard to find as mycelium. Sponges will be rare, but still worth the time to get it. I mean, what objects do people least get?
I would say given the circumstances stated, it's close whether it's cobwebs or mycelium.
So what do you think? Is there something else that should go on the list?
We could even open the topic wider and look at the rarest things to happen, such as a skeleton dropping a infinity bow, or the rarest mobs, which would probably have mooshroom at the top, unless you include the Bunny Rabbit Of Israphel from the snapshots. (Only spawns in extreme hills biomes, each time a rabbit spawns it has 1/1000 chance to spawn a evil bunny.)
Whats the rarest thing you have had happen in minecraft?
