A Terrible Fortress

Tab: NetherDifficulty: Medium

Tree path: Nether › A Terrible Fortress (advancements are independent: they can be completed in any order; the tree only guides progression)

Tree parent: Nether

Advancements are exclusive to Java Edition. The Bedrock Edition equivalent is achievements, which have different objectives.

How to get A Terrible Fortress

1. Enter the Nether through a lit portal, geared up: iron armor or better, a bow, food and a stack of blocks for bridging over lava.
2. Explore until you spot the dark red nether brick structure. Fortresses can generate in every Nether biome: the game splits the Nether into 432x432-block regions (480x480 in Bedrock) and each region rolls either one fortress or one bastion remnant, never both.
3. If a region gave you a bastion instead, keep moving: in Java each region has a 40% chance of a fortress (33% in Bedrock). In basalt deltas any structure attempt becomes a fortress, so fortresses are most common there.
4. Walk into the fortress itself. Just stepping inside completes the advancement.

Tips

Fortresses can generate buried in netherrack with only a bridge or a tower sticking out, so scan the terrain edges. Don't confuse them with bastions: bastions are black blackstone, fortresses are dark red nether brick. A fire resistance potion makes the search far safer.
