Blair is a fiery boss with a variety of skills. He has a huge arsenal of explosive attacks that are useful in many combat scenarios and is a specialist in strategic damage-over-time, making him a valuable Descendant.

Here's how to unlock Blair in The First Descendant.

There are two ways to unlock Blair. The first and easiest way is to buy him for 300 Caliber by going to the shop tab in the main menu. He is noticeably cheaper to buy than other Descendants, such as Valby. The second (and more daunting) way is to craft him through research, which requires various materials.

To craft Blair, visit Magister Anais, southwest of Albion. Talking to her will activate the research menu. Navigate to the Descendant section of the menu and select Blair. This section will show you all of the resources you need to craft the Descendant materials. The four main materials you need to craft are Blair Enhanced Cells, Blair Stabilizer, Blair Spiral Catalyst, and Blair Code.
