The second day on the server goes underground. Basket is down a ravine with johnfal_92, whose nameplate shows up on screen early on, and the plan is simple: get the diamonds, get some levels, and not die.
Diamonds at the bottom
One of them is at Y 16 and can see diamonds down in the ravine. A few minutes later: "Got those diamonds? Yep. Diamonds! There's more over here." The catch is the creepers. "I got creeper by these diamonds, so stay away." The ravine is full of side tunnels ("this is like swiss cheese"), and they get cleared one at a time, in the hope each is a dead end so they can turn around for the good stuff. One finally is.
The race to 30
Levels are on everyone's mind, so the iron goes in the bag too. Then comes a wall of gold ore. "I feel like I deserve to have more levels. I'm at 20 right now. No, I'm at 22." That turns into a race to level 30, with a short lesson on the enchanting table: the offers are "different for every person," and enchanting a junk item resets them.
Along the way the last arrows go into a witch, and there's a complaint about Minecraft 1.11: the sound for a breaking tool is gone. "It's very annoying." Asked what the server is, the answer is plain: "This is vanilla 1.11, no mods or any adjustments."
Sealing the caves
Skeletons keep dropping in from above. "There's one cave that went way up." The two of them talk about going up to light it, then decide to block the openings off instead. Somewhere in there a count comes up of 12 diamonds, "not too bad," enough to think about picks for branch mining.
It's a party
Then the cave above opens up. "Don't come up here right now. It's a party!" The zombies keep coming: "17 zombies, yeah, there they come." The guess is a spawner, "which would be great," or just a lot of zombies spawning up there.
They backtrack so they're not hitting each other, and someone remembers there's a shield. It doesn't go well. "Oh, this is bad. I am in danger." The retreat goes down a hole with about five skeletons and two creepers right behind. One creeper blows up.
Out of food
The other problem is food. "I'm gonna die because I have no more food." The reply: "I have ten potatoes if you would like."
This part of the cave is still bad news, so it's time to head out. A skeleton lands a shot, there's a witch, and then sandstone: "I'm actually apparently by the surface." The 30 levels will have to wait.
