What Klein Brings to Your Team

Klein is a melee fighter with solid damage output and some utility on the side, making him a solid choice for pretty much any team composition. He's not a one-size-fits-all type of guy, so he'll fit in anywhere you need him.

Unlocking His Quest Line

You must complete his side quest chain to recruit him. This chain is not available immediately, but only after the treasure is discovered with a question mark in the main story. After you get that, watch for quest markers or collectibles as you explore, as they will start his story.

Fully Clearing Areas

His quest line is easy to miss, so be sure to clear areas thoroughly and look at all markers you encounter. If he is not rushed to a spot, he may not find the trigger that begins his recruitment chain.

A Note on His Weapon

After Klein joins your team, remember that he has a poor weapon. It's worth upgrading it early or replacing him with another, as he will not be as damaging without one.
