Nether Structures

The centerpiece features are its towers and spirals, which generate as small dungeon-like builds you can climb and explore:

Crimson Tower

Found in the Crimson Forest, a tall spire built from nether bricks and crimson-themed blocks, with a latticed, multi-floor design and interior hazards and loot such as blaze rooms and hidden chests.

Warped Tower

The Warped Forest counterpart, built in teal warped materials with the same tall multi-floor tower design.

Netherrack Spiral

Out in the Nether Wastes you also come across netherrack spiral structures that add variety to the open terrain.

The towers double as points of interest and as small challenges when you drop into them looking for loot.
