Hardmode Ores Advanced Guide

Complete guide to Hardmode ore generation, mining, and crafting

Overview

After defeating the Wall of Flesh, smashing Demon/Crimson Altars with the Pwnhammer generates Hardmode ores in your world. Each altar smashed spawns one tier of ore, cycling through Tier 1 → 2 → 3.

Every altar smashed generates ore: 1st = Tier 1, 2nd = Tier 2, 3rd = Tier 3, then the cycle repeats with diminishing returns. Each smash also has a chance to convert a random stone block into Corruption/Crimson.

Altar Strategy

How many altars should you smash? Each set of 3 completes a cycle, but returns diminish and biome spread increases.

Smash 6-9 altars (2-3 full cycles) for a good balance of ore availability and manageable biome spread.

Each altar smash has a chance to convert a random stone block to Corruption/Crimson. Excessive smashing accelerates biome spread significantly.
