"So now I'm going to describe what's up here first before we activate spawners." There's an evoker up to the left, more evokers behind a wall that got blocked off, and creepers still spawning in. The charged creepers have to go first. "Oh, I need blocks, dude. You need to give me blocks."
Through the walls
The usual move is to tunnel over and break the spawners from the side. It doesn't work as well here. "The problem is, when we did that, it was when the guys couldn't really attack us. But these guys attack through walls." Someone says "I'm gonna die. Eat faster!" A minute later there's a charged creeper right on the other side of a wall, and then the chat reads "Scoti_Garbidis was slain by Vex."
A bed comes up, then gets broken. "I wanna be caught in a death loop with these vexes over my bed. That's my main goal for the rest of the afternoon." The gear gets picked up and carried back, and the bed goes down again.
An emerald and a second death
An emerald turns up. "Wait, what's this from?" "Invoker, yeah. Just an emerald." "You found the emerald and never said anything? You jerk!" Not long after, the chat says "Scoti_Garbidis was killed by Evoker using magic." Charged creepers come pouring toward the gap, and nobody wants them blowing up the dropped stuff. They get them, one more evoker spawner goes down, and the gear comes back.
Up into the tower
There's a tower overhead, and the plan is to get into it "in a really clever way." That takes a ladder, a block broken and another placed fast, and a lot of talk about not letting anything in. Opening a window to the outside gets a ghast's attention. The floor up top is thin netherrack with charged creepers above it, and there's no water. "Don't break any of this netherrack or provoke any of the charge creepers."
Up there are gray "stinky cloud" lines and a caged spawner. One of them breaks the cage to reach it, takes out the bottom spawner, and later the other one. Everything seems to drop Blast Protection books, so the very damaged anvil comes out and the books go on armor.
The cursed elemental
Around 24 minutes in, the vexes catch Scoti again: "Scoti_Garbidis was slain by Vex." There's talk of making a wooden pickaxe to dig back.
Then one of them finally sees the cursed elemental. "It's a bow guy, one of those skeleton bow guys from a previous level." Standing near it gives slowness, weakness and mining fatigue, "like an aura." It goes down, but there's more than one. They call them stinky guys, and there's another on top of a second tower.
Wool, way up
Poking a head out onto the surface shows a purple void with towers in it. "Oh, I found the wool." It isn't close. "It's way up. In the sky. Through the clouds with all these bad guys." An ender pearl comes up, but the idea they like better is an enclosed pillar going up, once the roof is secure. There's a regular skeleton spawner to the right. One of them puts torches on it, "because I'm cool like that," and that's the end.
