The deaths sidebar opens at Scoti_Garbidis 131 and BasketMC 98. The plan for the day is short: "We're gonna find four more keys." Then, "All right, Sunken Colony, time to get owned." They pick a building they haven't been in yet, one that looks to them like "a floating island of doom."
Creepers that float
There's a charged creeper inside and a spawner to take out. The first chest on Basket's screen is mostly cobwebs, with arrows, potatoes and a pair of Boots of Resilience (Projectile Protection II, Blast Protection II). A diamond pickaxe turns up too. "Whoa, stop the presses." It's "the only diamond pickaxe we've ever seen," so it gets put away.
The charged creepers here act strangely. Instead of coming at them, they spawn low and float up through the water. "I wonder if there's like some sort of custom spawner." One of them calls out an invulnerable charged creeper around the corner, and one of them kills it.
A platebody with extra health
Past a room of bookshelves, Basket opens a chest with a Symbiotic Platebody in it: Protection I, Blast Protection I, and +10% max health. "The protection stuff isn't super great, but... it's pretty cool."
Then comes the usual argument about the way in. One wants the door. The other wants to go outside and cut through the wall. "No no no no no. Over here, man. I'm telling you."
Down in the dark
They end up going down separately. The lower rooms are dark and crowded. "Real nasty bad stuff down here, like charged creeper right in my face." Spawners come out one at a time, and one of them can't stop thinking about Mario's water level music.
The voice chat fills in what Basket's screen doesn't show. The other one reports "two diamond blocks on the surface of the water" with a creeper spawner underneath, so "as you're trying to get the diamonds they blow up in your face." Later it's wither skeletons: "this is like the boss battle. They have diamond swords, diamond chestplate." The bottom of the lake has "little one-by-one holes where creepers spawn from and they float up." Then a run of good news, all from the other side of the wall: "I found an emerald," a potion of lucidity, and a bedrock block that "was loose in a chest." The chest calls it "a rare adminium block," and the guess is "you probably trade it for the armor upstairs."
Arcane Key #3
Basket's screen is the one that finds the next key. A flooded shaft with a water column leads to a small lit room, and there it is: a switch on an obsidian box under a sign reading "Arcane Key #3." "You want to do it without me or you want to do it with me? It's up to you." The answer is "Why don't you do it without me, man." The switch gets flipped, and the chat reads "BasketMC and Scoti_Garbidis Arcane Key #3 has been activated." "Good job." "Thank you."
The Archangel's Blade
The other one is still pulling loot out of the room full of mobs: "a gold sword that's sharpness five, knockback one, unbreaking three." The emerald comes up again, and they agree they don't need it to win. "It'll give us something cool."
Basket finds a large chest off on its own. "Tell me all the cool secrets." "I think it's not trapped." "That's not what I want to hear." It isn't trapped. Inside is an Archangel's Blade (Smite II, Fire Aspect I, Knockback I, Unbreaking II, +6 attack damage), and Basket comes away with a pair of unenchanted diamond boots.
With the water "just full of creepers," they call the episode while still apart and plan to meet up next time. Nothing plays after the credits.
The sidebar closes at Scoti_Garbidis 131 and BasketMC 98. Nobody dies. Arcane Key #3 is activated, and no wool, emerald blocks or upgrade blocks are placed.
