The last episode ended with Scoti slain by a Flaming Golem and the dropped gear lost. Chat reads "Scoti_Garbidis joined the game," and the two of them pick up below the trapped netherrack floor. The counter opens at Scoti 136, Basket 117.
Staying off the floor
First, a theory about last time. One of them guesses a creeper dropped on Scoti's head. The other went back down to investigate and blames "guys with bows" down to the right. Later that turns into a maybe, and a blaze becomes the other suspect. "They can knock you off of stuff, can't they?" "Yeah, that's why I did the safety rails."
So they take the high road. They split up and bridge along the walls, crouching so they can't fall, with rails on both sides. "Who would be dumb enough to walk on the floor in this place?" A moment later comes a softer version. "I shouldn't say dumb. Who's brave enough, right?" A blaze spawner goes down, then another spawner out by the painting room.
The library
There's a library coming up, and it looks promising. They meet up there, plug a hole where charged creepers keep coming out, and one of them cuts across an iron bar to reach the chest. "I should definitely walk across this iron bar, because nothing would ever knock me off of there."
Inside are boots with Protection III and Blast Protection I, which go straight on, "'cause they give you more life." There's also an Unbreaking III book, a Sharpness V book and some plain diamond tools. The library looks like a dead end, so they go after the emerald they spotted earlier.
Lava, poison and fire
There's a lot of lava under the next stretch, and one of them says that's the idea. "That way they can't path and run underneath it." Next is a big room with lava, cobblestone fence pillars, a chest on the far side and a blaze spawner in the middle. One of them goes for the chest while the other plays spotter, and it goes badly. "Oh good lord, I'm on fire and poisoned." The culprits seem to be what they call "poisonous spiders." "I feel like it's a booby trap. You're trying to kill me."
The next shrine
Further into the maze, one of them finds what they came for. "I found the thing we have to blow up." It's a shrine, with glass in the way, so they loop around through what one of them calls "my tunnel of doom." The mobs ahead start blowing each other up. "They're in-fighting."
Basket has an Arcane Bomb on the hotbar, something gets thrown down the shaft, and the spawner at the bottom goes out. They start bridging toward the shrine and stop just short. "Will we die? Can we get it? Let's find out how next time."
No one dies this episode. The counter ends where it started, at Scoti 136, Basket 117. No shrine is destroyed on screen. The monument isn't shown, so the totals carry over: 15 of 16 crystals and 10 of 12 emerald blocks.
