Fortress of War | Nether Fortress Update
by kanokarob
Fortress of War turns a Nether Fortress into a multi-stage objective-based combat challenge, with custom enemies and loot added to the bridges and gates of the fortress.
What it does
On first contact with a fortress, a boss bar appears and tracks every objective in the structure. The objectives are spread along long bridges, which often have to be broken through to reach the rest of the fortress. Once the objectives on a bridge fall, the fortress gates open and give access to newly spawned enemies. Destroying the final gate reveals the Fortress Matrix.
Four types of objective have different health behavior, and the fortress contains Wither Skeletons in full Wartorn gear, which can drop Wicked Apples. The mod adds enemies such as a Blazing Cannon that fires fireballs at players up to 64 blocks away, a Cursed Chest that hops and snaps at nearby players, and a Vile Root that bites the nearest player. Drops include Glowstone Dust, Basalt, Obsidian, Redstone Blocks, Rib Armor Trim Smithing Templates, Fire Charges and Blaze Rods.
The mod is server required and client optional. Players who join a server running it need nothing extra to fight, but the client can add it for the full experience. It is published for Fabric, Forge, NeoForge and Quilt, with files for 1.21.7 – 26.3, and it is a custom license that is not open source. Fabric, Forge, NeoForge and Quilt all share the same 1.3+mod file for 26.3, released 2026-09-15.

How it compares
Dungeons and Taverns Nether Fortress Overhaul has Fabric, Forge and NeoForge files for 1.21 – 26.3 under All rights reserved. Either side can run it, and neither needs it, so it fits servers that want the same fortress with optional client support. Updated Nether Fortress covers 1.21 – 26.3 on all four loaders under All rights reserved, and the client may run it without being required. Sensible Smithing Templates is open source under the MIT License, with files for 1.20 – 26.3, and a server can run it while players join without it.

What the author says
When a player approaches a Nether Fortress for the first time, a bossbar will appear representing the entire Fortress, and Objectives will be spawned throughout the Bridges. Although the Bridges are long and winding, you may need to break through terrain or other parts of the Fortress to reach all of the Objectives…
