Artifact
Mistletoe
The young shoot left outside Frigg’s oath-taking, which Loki turns into the weapon that strikes Baldr.

Overview
Mistletoe’s force in chapter 49 is not size or grandeur, but exclusion from the protective oaths. Frigg thinks it too young to swear; Loki learns this and takes the shoot. The thing that kills Baldr is precisely this overlooked exception.
