How to complete Jinx Fixes Everything Act 3 in League of Legends
Here are all the steps that you will need to take to complete the third Act of Jinx Fixes Everything in League of Legends:
Step 1: Interact with the workbench

The first thing that you will need to do as soon as the Act starts is to interact with the workbench which is right in the middle of the room. You will see a highlight of Jinx’s weapon which she will place on the table in order to make/repair it.
Step 2: Pick up the fuel source

The weapon will need a fuel source to work. To get it, look to the left from the workbench and you will find the fuel highlighted there. However, to maximize its power you will need to solve a series of sequences.
Green lights will flash in a random sequence and you will need to press the correct buttons accordingly. You will have to do it for three levels, and the sequence gets a bit harder with every level.
After you have reached three levels, you will have successfully juiced it up. So pick up and then head to the desk ahead of the workbench to pick up the device which will help with cooling.
Finally, make your way back to the workbench and assemble it. Jinx will now try it out, however, the test will fail as the weapon easily overheats.
Step 3: Get the pipe from the valves

To improve the weapon’s cooling you will need to get the pipe from the valves which is near the furnace. However, to get the pipe, you will need to prevent air from flowing through it. You will be able to pull this off by rotating the connecting valves in a certain direction.
The image above shows what you need to do and the valves that you will want to interact with to solve this puzzle.
Now go in and interact with the workbench again and Jinx’s weapon for the final encounter in Arcane will be done.
Step 4: Head out the door and complete the Act
For the final step, once the weapon is done, pick it up and head out the door on the left. Make your way down the stairs till you reach he mural of the Zaunites. There will be a small cutscene where Jinx steels her resolve and you are finally done with the final Act of Jinx Fixes Everything in League of Legends.
