I'll show you how to get Shroomite Bars in Terraria 1.4.4.9. To do this, we first need to kill the Wall of Flesh in order to enter Hardmode. Then we kill all three mechanical bosses. From them, we need to get all the souls and several Hallowed Bars. Then, on the Mythril or Orichalcum Anvil, we craft a Pickaxe Axe or Drax. And we go to the jungle. Here, underground, we can find Chlorophyte Ore. But to make it easier to find, I recommend using a spelunker potion. Next, we smelt Chlorophyte Ore into Chlorophyte Bars. We're halfway there. Now we need to find the Glowing Mushroom biome. Here we dig up everything related to the biome. We need a bunch of mud blocks. We also need Mushroom Grass Seeds. Somewhere on the surface of our world, we create a surface Glowing Mushroom biome. And a house in this biome for Truffle to live in. Next, we kill Plantera. Then we return to Truffle and buy an Autohammer from him. Now we approach the Autohammer, having Chlorophyte Bar and Glowing Mushroom in our inventory. And we craft Shroomite Bars in the quantity you need. Now you know how to get Shroomite Bars. That's all. Thank you for watching. Goodbye.
