Guide:Surviving in the Crimson

Surviving in the Crimson is hard without good gear. Here are some tips.

Armor
First, you should try to survive with at least Lead armor or Iron armor. If you've farmed Zombies you should have a Shackle with Warding which, combined with Lead armor, will give 16 defense. Ironskin Potions would also help. Then you can try gold. One you have gold, you may be able to fight the Eye of Cthulhu which may give you better gear.

Weapons
Melee: any Broadsword is fine, and Spear helps, too or get The Rotted Fork from the Crimson Hearts. If you already beat the Eye of Cthulhu, crafting a Blood Butcherer from the dropped Crimtane Bars might be a good idea. Ranged: any Bow is fine, and also get the Undertaker from the hearts. Magic: If you can, try to get Waterbolt and 60 Mana. Don't go too far down into the Dungeon, or you could get killed! Another good weapon would be the Diamond or Ruby Staff.

Accessories

 * 1) Shackle
 * 2) Aglet
 * 3) Panic Necklace from the hearts

Other help
Then, when ready, try to fight the Brain of Cthulhu. For more information on how to defeat it, see Guide:Brain of Cthulhu strategies.
