Overview
Project Onyx is an Add-On heavily inspired by the Old Ones Arm from Terraria. It adds a new customizable raid accessable by interacting with a new block. Customization including difficulty, enemy spawning frequency, and new in this update; Modifiers to give your raid a bit of spice!
Guide Book
When you spawn in, you will immediately be given the recipe for the addon guide book along with other important recipes. This book will open a UI when used, so you do not have to go back and forth from this page to your game. All information is provided in the book. This book is also required to craft core items from the pack.
Spawning in, you are given the recipe to the pack guidebook. This book will tell you everything you need to know about this Add-On. This book spawns an image in front of you like a normal book, and the item can be used to flip through pages.
- Onyx Raid-
The first raid type in this pack (and only for right now), is the Onyx raid. These guys are the masterminds behind the Universal Pylon system. When activated, you'll fight a handful of onyx robots, a sub-boss, then the main boss.
Equipment:
Like any add-on that adds something, you get some things out of this.
Both the Sub-Bosses and the Main Boss drop a handful of cool weapons. They mainly focus on large crouds of entities to keep things settled.
Crystals:
Speaking of items, the bots drop crystals that will help you in the raid. We both know you wouldn't read specs about every crystal so bump into them in game and see. :p
That's it for now! Next update will add a new raid and will spice things up even more and this update spiced up what was already here. Hope you enjoy!
