Things you should do upon entering hardmode

So, you have beaten the Wall of Flesh and don't know what to do next, this guide will help you do just that!

Smashing Demon/Crimson Altars

The first thing you should do after beating the Wall of Flesh, is smahsing demon altars (if on a corruption world) or crimson altars (if on a crimson world).

To smash the altars, you will need the Pwnhammer, which is dropped by the wall of flesh.

Demon Altar


Crimson Altar



The first altar will bless your world with either Cobalt or Palladium
The second Altar will Bless your world with either Mythril or Orichalcum
The third altar will bless your world with either Titanium or Adamantite

You will need a molten pickaxe or a reaver shark to mine palladium/cobalt.
Palladium
Cobalt

You will need either a cobalt/palladium pickaxe or a cobalt/palladium drill to mine mythril/orichalcum
Mythril
Orichalcum

You will need either a mythril/orichalcum pickaxe or a mythril/orichalcum drill to mine adamantite/titanium
Titanium
Adamantite

Notes: You make a molten pick at a hellforge with 20 hellstone bars (60 ore + 20 obsidian)
You will need a mythril/orichalcum anvil (10 bars) in order to make drills and picks of the
material
