How to Beat Grieving Golem

Boosted Analyze Reveals More Weaknesses

Octopath Traveler 2 - Osvald Chapter 4 - Boost Analyze
At the start of the battle, use Osvald's BP to boost Analyze and reveal more than 1 weakness. This will allow you to plan ahead in case you lose the fight.

Ideally having a Warrior, Hunter, Thief, or Armsmaster in your party will help as they have the widest range of physical attacks that can break the Golem. For elemental attacks, you should consider having a Cleric or Dancer in as a Secondary Job.

Breaking the Golem Consistently is Key

Octopath Traveler 2 - Osvald Chapter 4 - Break Golem Consistently

At the latter stages of the fight, the Golem will hasten its speed allowing it to move in multiple consecutive turns that can easily wipe out your team. Plan your moves accordingly, sometimes it's not about dealing the most damage, but dishing out the most number of attacks to break an enemy that wins the bout.

Break and Boost System Guide

Turn Osvald into a Cleric

Octopath Traveler 2 - Cleric Osvald
Since the Golem's weaknesses shifts, you can make Osvald's secondary job Cleric as its Light-attribute attacks cover the Golem's first set of weaknesses while Osvald's Icewind can reduce the Golem's SP once its weaknesses change.
