Possibly a Cabbage Posted:

At least it’s not a kind of item we’ve had before, that’s got to be worth something. Prior to today we’ve had at least one of all types of equippable items except fetishes and hardware (also except different kinds of .moars, but .moars won’t be appearing in itembuildr anymore).

So to the extent that “it’s good to cover everything” it’s good to have a fetish.

Keep in mind that this is the third item that gives douchebaggery.
