Easy Way to get the Vampire Knives.

This guide will hopefully give you some information and ways to easily get the Vampire Knives.
Some may want to do this because the vampire knives are a great weapon for people who are having trouble in late Hardmode.

Overview

This guide will show you an easy way to get the Vampire Knives, and all the items and steps required to get them.
This includes:

• creating a Crimson World and gaining access to the Dungeon
  
• Going into the non-hardmode dungeon and finding the Crimson Chest
  
• Creating a Crimson world and activating Hardmode quickly
  
• Farming for the Crimson Key (or Key Mold, depending on version)
  
• Defeating Plantera and the Mechanical Bosses
  
• Returning to the non-hardmode dungeon and looting the Crimson Chest
  
• Differences in setup between 1.2 updates and 1.3 updates
  
• SUCCSESS!! :D

This video is a pretty decent demonstration of why the Vampire Knives are a popular choice for decent game progression:

Yeah... They can be quite overpowered...

I should note that some people may think that these methods are possibly "Cheating," and that the Vampire Knives themselves make the game "too easy." Keep in mind that this is mainly for people that are having trouble with certain challenging parts of the game. For example, the Pumpkin Moon...
On With The Tutorial!!

World Generation

To start off, you will want a character with at least hallowed armor, and a few really good mid-hardmode weapons. Basically, if you can beat the Wall of Flesh without even thinking, you're probably ready. Kinda like this:


An inventory slightly lesser than this would suffice for a ranger, definitely don't need the Candy Corn Rifle...


Now, we generate a couple of new worlds, both of them Crimson.
The first one will be normal, not Hardmode. this is where we will find the Crimson Chest.
The second one will be hardmode, and will be where we kill Plantera and Receive the Key Mold. Finally getting a Crimson world might take some time, because whether or not a world is crimson is randomly decided by the game.


Now that that's done, we need to go into the non-hardmode world and find the Dungeon.
Once you do find it, wait untill night and quickly kill Skeletron. now enter the Dungeon and search around untill you find the Crimson Chest. Mark the chest with a torch. Now, make a tunnel going directly to the chest form the surface. Congratulations, you have found your Crimson Chest!


Now go into the world that will be Hardmode. Now start tunneling straight down untill you hit the underworld. (make sure to steer clear of any lava in the way...)
Now make a small 100-300 block area of flat land. (500 if you really want to be sure)
Summon and kill the Wall of Flesh. You only need to do this once. Now use your Magic Mirror, assuming you have one. All the Prerequisite stuff is done, yay!

Key Molds and Bosses

Now that your Hardmode world is actually Hardmode, find the Crimson. Now journey into the Underground Crimson. Once there, you can set up an AFK farm somewhere in there. I imagine something like this would do...
Beware of the Floaty Gross enemies, as they go through walls... Also, don't forget a Water Candle (increases spawn rates to make the farming faster).


Once you finally have the mold, you may have also gotten a few Mechanical Boss spawn items. (Mechanical Skull, Worm, Eye) If you are lucky to get one of each, great! If not...You might have to craft some of them. Once you have them all, start fighting the Mechanical Bosses.
Once you have killed them all, you will have the souls neccecsary to craft the Crimson Key. And you will have enabled Plantera Spawns! That's good, we need that...


Time to venture to the Jungle. Underground Jungle, that is. Find a Plantera Bulb, and prepare.
If you don't have very good armor/weapons, you may need/want to build an arena. Tons of space and wood platforms should do. Campfires are quite Neccecsary! Summon and fight the boss. If you beat it, Hooray! If you didn't...Try again! Once you have the Temple Key, Immediately craft the Crimson Key. One step remains...

1.3 Update

If you are playing Terraria in the latest 1.3 Update, things are different. The most notable difference is that defeating Plantera is no longer needed to be done. Since you can unlock the chest even in a non-hardmode world (you just need the key), all you needed to do was defeat Plantera in a different world and farm for a key mold. Now, the way dungeon keys are handled is different. Temple Keys (which are dropped from Plantera every time she is defeated) used to be a crafting component and when combined with a key mold, the result was the final dungeon key. Key molds have been removed entirely and now the keys are just flat-out dropped by the correspondimg biome's enemies with the same drop chance as the molds. Now you can skip Plantera (and the Mechanical Bosses, I believe) entirely and farm for the key (in a hardmode world, of course)!

However, this comes at a price. It is significantly more challenging to farm for keys ever since the Meteor Head exploit was removed. That was never too big of an issue. That is, until 1.3 hit. It still isn't a big issue for people on normal hardmode worlds, you'll just have a harder time if you want to do it AFK. I wish I could say the same for Expert Mode. If you go AFK in Expert Mode without knowing EXACTLY what you are doing, there's a very high chance you will end up dying. My recommendation is to create a setup where, although you will never be fully AFK, you still won't need to do much. Yo-Yo's and the Death Sickle are absolutely phenomenal for this type of setup, as they will either go through or around solid walls. This allows you to be in a safe, solid structure while you completely destroy the enemies around you!

The Easy Part...

The title says it all, it is by far the easiest part.
Go back into the Non-Hardmode world, and go to the Dungeon. Remember that tunnel you made? That tunnel makes everything easier! Go down the tunnel, but beware Fall Damage.
Open up the chest, and you're done!! It was that easy! The Vampire Knives are officially yours!

OPTIONAL: If you want a challenge, you can test out your newly-aquired weapon by killing all of the bosses that made you stressed and angry! And now when you travel to a Hardmode Dungeon, you can fight back a lot easier! You could even find another set of Vampire Knives and give it to your best friend! It's fun for everyone!

spread your crimson onto your corruption world

[Directionally Challenged Engie]

any tips for getting them in a corruption world? i need them but i cant get my crimson world to hardmode, PLUS im to lazy to do that whole thing above XD

[Real Tom]

I didn't really understand how u worded this guide, so can u try making another one? I also NEED vampire knives since I'm doing a thrower playthrough. Thanks!

@Bucephalus: One way I've heard about farming for keys is clearing a large space in the corresponding biome, and making some form of enemy collection/killing mechanism (dart traps and any form of trap from the jungle temple work nicely). AFK farming certainly used to be easier, but you can still get a key without too much of an issue (hopefully). I guess I'll have to add an updated section that accounts for the 1.3 update...

[ValeN]

um.. my terraria is 1.3 so its so hard to AFK farm it then how do i do it?

[Terrarian Waffle]

yeah just look up the "how to get creative mode mod on terraria'' guide

[PhoxLogic]

@Terrarian Waffle: Mods? Oh, I just can't figure out how to do those on Terraria... I can make mods and modpacks with Minecraft though, but that's a different game entirely...

[Terrarian Waffle]

okay well i downloaded a mod i haveeverything now so yeah

[PhoxLogic]

@Terrarian Waffle: Well, I don't have any exact numbers, but... It takes a very long time. In some versions the chance is like, 1 in 1000 or something like that. I honestly don't know if they ever changed that.

[Terrarian Waffle]
