¶ Getting to the Domain
There are two ways to enter the Brain's domain:
- Use an Brain of Cthulhu Map on a Map Device and enter, which is dropped by any npc (1/1000 chance) after A Heart Still Beating quest is completed
- Allow Lloyd to destroy 3 hearts during the questline, A Heart Still Beating. Lloyd can often be found in the above ground Crimson once Eye of Cthulu has been killed.
