Found a cave, found a mob spawner. Turned it into an XP farm, & made my house there. Ended up finding 10 diamonds, made a sword and pickaxe, full iron, 3 stacks of iron, and I'm about to get a level 50 enchantment on my sword/pickaxe. Not sure which one.
Full double chest of Bow (Power 1) and bones and arrows.
My current singleplayer world is pretty similar:
This was the cave I chose to use. I was inspired to create it when my friend converted a cave on my server into his house.
This is the first skeleton spawner I found. I hadn't expected to have been this lucky, and quickly turned it into an xp farm.
This is the enchanting area, conveniently located above the exp farm.
This is another skeleton spawner I found. It's on the other side of the cave, and they're not close enough to combine. I don't know what to do with this one.
This image shows what I've done to branch out to the surface. Visible is a tower and bridge, both built and designed by me (though exceedingly simple, I'm sure others have come up with them) and part of an X-Light 9000, not designed by me.
