Episode 9 of Minimalist takes Team B.S. into Killer Karst, a cave dungeon of water, vines and trees on Kaladun's complete the monument map. Basket and Scoti_Garbidis rush it, get pushed around by creepers and water, and find the Lime Wool. Back at base, the monument goes from four wools to six.
Blitzing the cave
The plan is to "charge in" fast: "this one's gonna be like the other cave thing where we need to sort of blitz it." Creepers are waiting right away, and more show up in the back. Boats are lying around the water, and Basket ends up sitting in one ("oh, I'm in a boat"), then picks up a Slightly Damaged Anvil. Two spawners sit side by side at the back.
A waterfall ride that goes nowhere
A waterfall in the corner looks like a ride. "We totally want to ride a boat down this thing. It's gonna be awesome." The boat will not go down it, so out they climb and walk instead, lighting things up and breaking a spawner as they go.
A sign for the next dungeon
Digging through, they open a gap onto a dark room of obsidian and colored glass, with a sign reading Nebulous Nexus. That is for later. Here there are spiders, skeletons and creepers everywhere, and a chest holds potions. One of them comes out with "two boats and some bones." Basket uses a splash potion of healing and eats a golden apple to stay in the fight.
The lime wool
Near the wool, flowing water keeps pushing them downward. "It's a good thing we took everything out up here first." A chest beside a block of lime glass holds the Lime Wool, and one goes into Basket's inventory. Its tooltip reads "From Killer Karst."
Two more on the monument
They head home to "put the wool on the thing, the monument." The row already holds white, orange, magenta and light blue. Scoti_Garbidis places a yellow wool and Basket places the lime, making six. A yellow wool in Basket's inventory afterward reads "From Aetherial Archive." The Deaths board still says Scoti_Garbidis 7, BasketMC 5. Next stop, they say, is the Nebulous Nexus.
