The deaths sidebar opens at Scoti_Garbidis 155 and BasketMC 113, one higher for Scoti than where last episode closed, with no death on camera in between. Team B.S. is still in the Netherhorde fortress, the boss is still missing, and the TNT is still out.
A theory about the towers
It starts rough. "On a scale of 1 to 10, when it comes to bad ideas, I just had probably the worst idea I've ever had... I'm in a room with guys, one block wide." About a minute in, chat reads "Scoti_Garbidis was slain by Netherhorde Warrior," and the sidebar ticks to 156.
Then one of them has a thought. "The four tower things? They surround that middle tower as if they were defending that tower. Maybe that's where we need to go." So the plan for the episode is the keep in the middle.
Blasting down, floor by floor
The method is the usual one: dig a hole, drop TNT, back up, look. "Commencing backing up." Each blast opens another room below, usually with a spawner in it. One of them is down to "five hearts" and eats potatoes, and admits, "I don't have that sweet armor that you have." The mobs keep finding ways up: "I just learned they can get up here." "Oh, they can climb up the water. Get rid of the water."
A chest sits right next to one spawner, and that slows things down: "I feel like if I do that, it's going to take out the chest, which might have some goodies."
About ten minutes in, chat shows "Scoti_Garbidis was slain by Netherhorde Warlord," and the sidebar reaches 157. The gear gets picked back up ("I got some of my stuff"), and the loot that follows is quoted as "16 diamonds" and a bow one of them calls the "Blazing Ballista."
Burned
The next floor down is on fire, and it's full of cage-helmeted mobs tagged Netherhorde Warrior, several of them burning too. "Wow, these guys hit a lot." "Everything looks the same when I'm on fire." Basket's health drops fast. "I can't heal." The death screen follows, and chat reads "BasketMC burned to death." The sidebar moves to 114.
Basket respawns and restocks from their own chest, and the inventory soon shows a Diamond Helmet with Respiration III and Blast Protection IV. Somebody's lava comes back too: "I got my lava back."
A dud, then a library
The keep isn't paying off. "I think this place is a dud." "Yeah, it's just loot, man." One of them finds a small room with "a chest and the bed... two beds," holding "two emeralds," books, "diamond boots" and a "gold apple." Below it is a library, and the library has a spawner.
On Basket's screen, end stone goes up across the gaps and lava goes into the room. "Oh, bookshelf got on fire." "Took out the spawner." One gap is left a bit too open: "Fun fact, kids. Spiders can get through a one and a half size block."
Back up top
"Now this is the bottom level, right?" There's talk of digging further down in the middle, but it's time to stop. Basket rides the water back up and looks down on the keep they've spent the episode blowing open.
There's no gameplay after the credits.
The sidebar closes at Scoti_Garbidis 157 and BasketMC 114. This episode: Scoti 2 deaths (a Netherhorde Warrior and a Netherhorde Warlord), Basket 1 (burned to death). No wool, emerald block or upgrade block is placed.
