Bretons are the most powerful when it comes to magic, but you know what’s better? Khajiit.
Khajiit have a combination of stealthiness with talon attacks that make them perfect for sneaking up on foes and cutting them down in a strike! It also helps they can go back to increasing their stealth level during combat by simply pressing the duck button (caps lock, for those uninitiated), making it easy to hit an enemy’s back or flank from behind without being noticed first. Dragons beware!
