After that battle, I thought "what next," and it was suggested that I get Molten Armor (... Read All Recently, I successfully beat The Brain of Cthulhu after making Crimson Armor (http://terraria.gamepedia.com/Crimson_Armor) and a Blade of Grass (http://terraria.gamepedia.com/Blade_of_Grass). It was a tough battle. I've only beaten this boss once and I stopped trying once I did. I fought it probably 3 or 4 times in total. I was afraid that I'd end up destroying all the demon hearts and wouldn't be able to summon it again, but luckily there are still some left. In the battled I used an Eggnog (to boost all stats) and a Thorns potion (because it runs into you).
After that battle, I thought "what next," and it was suggested that I get Molten Armor (http://terraria.gamepedia.com/Molten_armor). It was easy to mine the needed obsidian as I found some lava hiding under some water. The obsidian was in between the two and every time I mined some obsidian, some more was created. The hellstone that was required was much more difficult to obtain. I went back to the Underworld, where I had previously had trouble surviving. This time, however, it wasn't that difficult. I did find it humorous that I was defeating fire enemies, such as Hellbats, with a Blade of Grass. You would think such enemies would be immune to a sword made of jungle grass or that the sword would catch on fire.
Luckily, I was able to mine the amount of hellstone I needed, but I found a tip to share. It is a good idea, when mining hellstone, to have something else in between your character and the hellstone. It's also a good idea to have an Obsidian Skull as well. But, while mining the hellstone, I found out that lava comes out of it, so I almost always made sure there was dirt or something between me and the hellstone. Of course, I didn't always follow that tip as I have an item that gives me 7 seconds of protection from lava.
Not only was I able to make a set of Molten Armor, but I also made a Flamarang (http://terraria.gamepedia.com/Flamarang) and finally a Firey Greatsword (http://terraria.gamepedia.com/Fiery_Greatsword). I have not yet used the sword I made, but it was nice to upgrade the Zealous Enchanted Boomerang to a Flamarang. I did not sell my Crimson armor, I put it in a chest, but I'm tempted to use it again because even though it does not provide as much defense as the Molten armor, the set bonus is faster health regeneration. Still, one thing I wish the set of Molten armor would provide is immunity to lava, that would have been sweet.
I'm still hoping to find something that provides me complete immunity to lava. I'm also still hoping that I find a key to those chests I found in the Underworld. I also need to talk to the Old Man near the Dungeon so I can check that out. Also, I defeated the Goblin Army that arrived and I met the Goblin Tinkerer, but he ended up falling in lava and dying. I'm hoping he's respawned some where so I can find him again, but if he hasn't, I'm ready to defeat the Goblin Army once again (that would be for a second time).
Anyway, that's my latest Terraria update. I thought I'd write a new post about it instead of just commenting on my original post. Hopefully soon, I'll take a screenshot of my character to use as my avatar. I'm thinking I might use one without his armor (because I want to show off all the blue I put in him). I may also take an updated screenshot of my house, since I've added one or two floors since I took the last one.
Your comments are always appreciated and I also greatly appreciate the help and suggestions you have given me (with regards to Terraria and CheerfulGhost). I really do enjoy the game and this website. =)
