The towers in Tower of Fantasy are quite interesting. One may be free, but the rest of them are earned by collecting their parts and piecing them together. Collect all of the components and you may unlock the other mount you want. The Omnium Beast mount is a rather cool pair of legs that will take you around the map. The Omnium Beast left arm is also included in this guide.
In Tower of Fantasy, how do you get the Omnium Beast Left Arm?
The left arm is perhaps the easiest to obtain out of all of the Omnium Beast pieces. This piece only requires you to go to a specific area and retrieve a code. Before you can do that, you will need to go to the Banges region. This is the second region you will go to in the game.
Head south from the Banges Shelter Spacerift to the bottom of the region. It's a large metal structure that supports it. Link it so you can come back here later (trust us, you'll need to).
Search the area for four scrapper robots similar to the ones you see at the top of Omnium Towers. Each of these robots will give you a piece of the four-digit code that disables the barrier blocking the left arm. Once you have all four digits, go back to the building with the barrier blocking you from entry.
The code for the barrier is 1647. It is the same for everyone. Open the Supply Pod inside to get the Omnium Beast Left Arm. The Supply Pod inside is a timed one so you wont be able to open it immediately. Make sure to come back later to claim your reward.
