엇, 은하 로또?

You can use a support Fu Xuan for this achievement.

This achievement has no cultural references in the English and Chinese versions. It is specific to the game. Cosmic Big Lotto is a Curio that gives the player a small chance of receiving 1 Curio, but also a small chance of destroying this Curio and all characters losing 99% of their current HP. Since Fu Xuan has the ability to restore her HP, given that it reaches below a certain threshold, the chive's title sounds like she's mocking the Curio's negative effect.
