Nether Fortress Compass
by 486287441
Nether Fortress Compass is a server-side adventure mod that turns Ruined Portal chests into a route to the nearest Nether fortress.
What it does
Players find a Ruined Portal in the Overworld and open its chest, which gives a compass that points toward the nearest Nether fortress. Each chest pays out one reward, and the claim is saved with the world, so a chest cannot be looted twice. Only a chest placed inside a generated Ruined Portal triggers the reward, and the compass points through the Nether coordinates that match the portal's position, searching up to 100 chunks around them.
The compass works with the normal compass and lodestone. A player places a lodestone near the fortress and the compass becomes bound to it, so a repaired portal in the Nether can be followed by the needle. The mod is server-side only, so players join without installing it, and it is built for survival progression on existing worlds. Files cover 1.21.10 and 1.21.11 on Fabric, Forge and NeoForge, and the mod is released under All rights reserved, so it is not open source. No required dependency is listed for Fabric, Forge and NeoForge.
Key features
Ruined Portal reward
A chest inside a generated Ruined Portal hands out a compass aimed at the nearest Nether fortress.
Nearest-fortress guidance
The compass searches the Nether region matching the portal's position for the closest fortress.
Lodestone binding
Placing a lodestone near the fortress binds the compass to it, so the needle points at that spot.
One reward per chest
Each Ruined Portal chest pays out once, and the claim is stored with the world.
Full inventory handling
If the player's inventory is full, the reward drops safely nearby instead of being lost.
