Frontiers (ALPHA)
by Artyrian
Frontiers is an alpha Fabric mod for Minecraft 1.21.1 that adds structures, bosses, ores and tool mechanics, spread across the world's progression from the start to the Ender Dragon.
What it does
Frontiers reworks the progression of a survival world. New bosses appear both before and after the Wither, and several existing items gain extra uses. The ores Cobalt, Verdinite and Vivulite generate during world creation, but they cannot be obtained until the Wither is defeated. Their tools are stronger than Netherite, so getting them takes some effort.
The author describes the mod as a Vanilla+ expansion that adds little to the base game in each area and stretches the time between starting a world and reaching the endgame. It is inspired by progression routes in games such as Terraria. The mod adds new tools, structures, crops and building blocks, and it works with EMI and JEI, including custom recipes. Frontiers runs on client and server, so the server and every player need it, and it is released under All rights reserved, which makes it not open source. The source code is public. The author states the mod is in an unpolished and unbalanced alpha state and that feedback is welcome.
Key features
New bosses before and after the Wither
Bosses appear at points in the progression on both sides of the Wither fight, adding encounters the base game does not have.
Gated ore tiers
Cobalt, Verdinite and Vivulite generate in the world but only become usable once the Wither is defeated.
Expanded existing items
Several existing items gain new uses, so familiar gear has a role in more stages of play.
New structures and crops
New structures, crops and building blocks are added to the world and to the Vanilla+ progression.
