Ruby Expansion
by alpogeday
Ruby Expansion brings ruby-themed blocks, items, custom portals, mobs and bosses, plus a generated structure, to NeoForge worlds.
What it does
Players who want ruby content find blocks, items such as a ruby shield and ruby elytra, and custom mobs in one mod. Custom portals and a generated structure add places to explore, and the bosses give the adventure a goal. Client and server both need it, and every player on the server must run it too. Builds target 1.21.1 – 1.21.11 on NeoForge, and the code is released under All rights reserved, so the mod is not open source.
Key features
Ruby blocks and items
Ruby-themed blocks and items include a shield and elytra, adding gear beyond the vanilla set.
Custom portals
Portals lead to dimensions with new mobs and structures, giving each trip a different setting.
New mobs and bosses
Custom entities and bosses populate the mod, with unique generated structures to find.
