Episode 17 of Minimalist starts at the base on Kaladun's complete the monument map, where Team B.S. add an iron block to the monument. Then it is back to the lab from last time, where a witch kills Basket, and on to a new dungeon floor with holes that drop straight into the void. By the end one wool has come out of it, and it is headed for the ender chest.
Iron on the monument
Iron ingots come out of a chest in the base and get crafted into a block of iron. It goes on the monument shelf above the Iron Block sign, next to the empty spots for the emerald, gold and diamond blocks. On the recording: "we don't have enough for the other stuff."
A witch gets Basket
Back in the lab, the room past the glass cases is full of blazes and caged spawners, and fire is everywhere. Then the chat reads "BasketMC was killed by Witch using magic," and the Deaths board moves to BasketMC 12. "There's a couple of them." Scoti_Garbidis, down to half a heart, blocks the room with dirt and opens it again when Basket gets back. Once the witches are trapped, a chest of soul sand turns up. "Oh my goodness, we're gonna make potions."
The haul goes into a regular chest "that we both have access" to, rather than an ender chest.
Potions at the checkpoint
With fire resistance running "for two and a half minutes," one of them climbs a ladder into another spawner room, and a quick dig makes a shortcut back. A large chest is full of potions of healing. At the checkpoint room with the bed, the brewing stand gets glowstone, then gunpowder: "I'm gonna make them splash cuz I got gunpowder." Fire resistance comes off the stand too.
Holes in the floor
The new area starts with a checkered hall and a maze going down. On the recording, a sign says "do not enter, seriously," and one on screen reads "The energetic creature lab is closed forever!" Past it are creepers, and "we can't put torches in." Then the floor turns out to have holes in it. "It might go through the earth." Under the half slabs and the dirt there is nothing but void. "I don't want to step on anything that doesn't have bedrock underneath it."
They work along the edges pulling out spawners. "If you see dirt, it's void underneath." Then: "Don't blow up the wool." A moment later, "I got a wool." An enchanting table in the next room looks like a trap that "was supposed to turn on the lights," and the chests there get emptied.
Where it ends
There is still one more thing left in this intersection. For now, the wool goes in the ender chest and the episode signs off, with the Deaths board at Scoti_Garbidis 14, BasketMC 12.
