Use Pillars as Platforms

You'll obtain the new Omnium Handcannon Relic at the start of Ruin A-03. This allows you to make pillars on any wall which are conveniently climbable on all sides.

Create a Pillar on the Platform to Cross the Pit

In the final room, you'll find a long pit with lasers and a single platform moving across. Use the Omnium Handcannon to create a pillar on top of the platform and ride on top of it. The pillar will go over the top of the lasers and allow you to ride safely across the pit.

How to Defeat the Boss in Ruin A-03

Vulcan Boss Overview

Vulcan
Difficulty	HP	Level	Element	Weakness
Easy	3 Gauges	18	Volt	None
Normal	3 Gauges	30	Volt	Flame
Hard	3 Gauges	44	Volt	Flame

Double Jump Over its Beam

Vulcan will sometimes fire a beam in a circle around itself. You can jump over this beam with a double jump. If you dodge it successfully, you'll have a window where you can attack freely, so don't miss the opportunity.

Climb Onto the Platform when Warning Text Appears

When Vulcan's shield gauge fills up, warning text will appear on the screen that electricity will run across the field. When this happens, jump on one of the four platforms which comes out of the ground to avoid the attack.

Takes Extra Damage from Fire in Normal and Hard Modes

On Normal difficulty, it takes an extra 75% damage from Fire attacks, so prioritize switching one in for this battle.
