How do you unlock yeti?

I just finished ember of rage. And didn't get this unlock. What did I miss?

You need to find the Yeti Mind Controller helmet and use it to capture 8 yetis. It's a fairly common drop from the boss in the Orc starter zone, so I'd recommend just making Orc characters on Normal difficulty and rerolling until you get it. Then you can take it to the Yeti Cave. You have to damage the yeti to low health before you can activate the item and target them.
