How to Beat The Steam Tank Obsidian

Focus on Destroying Front Parts Immediately

Octopath Traveler 2 - Focus on Front Parts

The Steam Tank Obsidian has three parts protecting its weaknesses and raising its shield. Try to focus on destroying The Cannon, Smokestack, and Glacis Plate as soon as possible to unlock the weaknesses and bring down the tank's shield value to a more manageable value. The different parts also have vicious attacks and can really do a lot of damage if they can all attack on the same turn.

Time Your Attacks and Breaks

Octopath Traveler 2 - Time Attacks and Breaks

The different parts of the Steam Tank take several turns before they launch another attack. Always make note of this to determine which parts you can currently focus on and ignore for the turn. Tracking this will also allow you to break them at the right time to extend their inactive turns.

Break and Boost System Guide

Utilize Attacks Targeting All Foes

Octopath Traveler 2 - Utilize Multi-Target Skills

Despite having inactive weaknesses, the Steam Tank can still take damage while the other parts are still present. Utilizing multi-target skills such as the Hunter's Draefeni's Bow, the Apothecary's Sweeping Cleave, or the Dancer's Dagger Dance will allow you to decrease the shield value of the other parts while still dealing damage to the Steam Tank.

List of All Skills

Launch Heavy Attacks When Weaknesses are in Effect

Octopath Traveler 2 - Launch Heavy Attacks

The Steam Tank can repair itself bringing back all the other parts to life. So once you are able to unlock its weaknesses, break the tank and launch all your best attacks to try to destroy it as soon as possible.

"Tracking this will also allow you to break them at the right time to extend their inactive turns." The "X turns until it can attack" doesn't reset when you break them btw.
