maybe eyeballing the increments of poison was a bad idea

Mithridatism, or the act of poisoning oneself in gradually increasing increments, is all in a day's work for a Fatui Harbinger.

When Childe takes just a little more than he's supposed to, however, things don't go so well. But when he gets out of this, his immunity to the poisons will be stronger than ever, so it can't be that bad. And at least Zhongli's here to take care of him through it all.
