HARDMODE: ON
HARDMODE: ON is a Forge cursed mod for 1.20.1 that adds ores, tools, armor sets and a new dimension to an existing world.
What it does
Players who want a harder start will find ore veins spread through the world, including rare ores and large deposits inside air caves that generate below Y 25. Full tool and armor sets are added as well, some with unusual names and colors, alongside a food item and analog stone tools.
A new dimension is reached through a portal built from magma blocks instead of obsidian, and a Lava Stick can be found in dungeons to help reach it. Ruined Lavadimhell portals and a range of trapped chests, a 5x5 door structure and a TNT block with 128 diamonds add structures across the world. A server running it needs every connecting player to have it too. Files are published for Forge only, for 1.20.1, with 0.0.7 as the latest file, released 2026-08-03. HARDMODE: ON needs no other mod to be installed, and its license is All rights reserved, so the code is not open source.

Use cases
Harder survival worlds
Players who want rare ores and unusual gear early in a survival world can use the ore caves and tool sets to shape their progression.
Exploring a new dimension
Adventure players can reach the added dimension through the magma portal and search its content.
Who it’s for: Players who want a cursed, unusual add-on with new ores, tools and a dimension. The mod has a rough, informal author text and a single version, so it suits players who are comfortable with that.
