Iron Islands
by whitnlan000
Iron Islands is a Forge magic mod for 1.20.1 that builds a progression around five dimensions, boss fights and crafted magic blocks.
What it does
Crafting blocks together opens a bonus dimension that holds the block used by the other dimensions. A dimension is built entirely from iron-themed material, and the block it contains can be processed into tools. Placing a campfire next to a villager turns that villager into an explorer who trades magic gems and rare items.
Progression passes through a portal igniter, which lights a nether-shaped portal and creates the portal block that matches it. Magic torches are crafted with a staff in place of a stick, and a torch can turn a villager into a spy. Spies lead to four new bosses, among them the Magic King, who appears after a magic throne is placed from four magic blocks and a carved pumpkin.
Iron Islands requires no other mod. A server running it needs every connecting player to have it too. Files are published for Forge only, for 1.20.1, with 2.0.1 as the latest build, and the code is under All rights reserved, so the mod is not open source.
Key features
Five dimensions
Five dimensions are added as full blocks of content, each reachable through the progression.
Portal igniter
A nether-shaped portal lit with the igniter creates a portal block that corresponds to the igniter.
Staff-crafted magic torch
A magic torch is crafted with a staff instead of a stick, and it turns a villager into a spy.
Skeleton summons
A stonecut bone block yields a skeleton block, and placing it summons a boss called Magic Skeleton.
