The world changes
Defeating the Wall of Flesh permanently starts Hardmode, changing enemies and progression. New ores belong to the following progression steps rather than all appearing automatically at the transition.
Plan equipment upgrades
Pre-Hardmode gear struggles against harder-hitting enemies. Prioritize progressing to new ores and replacement armor after the transition.
Prepare before defeating the Wall
Prepare defenses, healing and mobility before the transition. Being able to defeat the boss is different from being ready for the resulting world.
Build housing and attract NPCs first
NPC housing needs walls, an entrance, lighting, a table and a chair. Residents create a shopping and recovery base and help meet the Eye of Cthulhu's 3-NPC spawn condition.
Build an arena before fighting
Platforms shape boss fights. Long, flat paths with healing and movement prepared make attacking while dodging easier.
Check your world's evil
Corruption or Crimson is set at world creation, changing the evil boss and materials. Check which your world has before following instructions.
Plan for the Steam version's language support
Without official Japanese on the Steam listing, item names use English or another supported language. Japanese guides and community translations provide alternatives.
