Mythology · True or False?
The answer is False.
In the myth, Baldur was invulnerable because his mother Frigg took an oath from all things not to harm him, except mistletoe which she considered too young and harmless to bother with. Loki tricked his blind brother Höðr into throwing a mistletoe dart at him, which killed Baldur (though he was revived after Ragnarök). Fun fact: his skin was impenetrable and the gods would jokingly throw their weapons at him and watch them bounce off, including Mjölnir, Thor's hammer.
