where is the blade of virtue spell

chaos king

:?: I am wondering in the description of the cult of the storm king there is a spell called blade of virtue listed. Unfortunately I cannot find it anywhere in the book. I am wondering if someone can give me the details of this particular spell.
I'm guessing here but I think that it is supposed to be Bladesharp.

It could be Fireblade, but I think themetal rune fits in better than the fire rune.
