Octopath Traveler 2 - Decaying Temple

In order to reclaim the stolen sword we heard about so long ago, we must enter the Decaying Temple, but the door will only open if someone comes alone. Temenos and Agnea are the best picks for this, with Temenos having a bit of an edge due to his latent. Make sure you find the hidden spear here.

As for Karma, the boss must be broken periodically otherwise it will use an instant kill move that bypasses instant kill protection (or there could be a translation error as there are quite a few of those). His weaknesses will change, so you will need someone a little versatile to constantly break him. Eventually, he will not have weaknesses anymore, so you will need either the Temenos Latent or the Dancer break move unless you want to use an item.

As you can tell, I am disappointed that the exact reason I gave Temenos the shield he is using failed its one job.
