Werewolf stat block ToV

[little hound]

Hello there. I’m running an adventure where a werewolf will be making an appearance soon and I was looking at the stat block in the Monster Vault (compared to RAW 5e) and I believe that some text is missing under its bonus action: Hungry Growl. The paragraph ends with “The target must succeed on a DC 13 Wis Save”.

It doesn’t specify what the result is on a failure or if there’s a partial effect on a successful save. And the text does not continue on the next page to below the illustration.

Is there someone who knows what the rest of that entry contains? Or is there an errata document somewhere?
Thank you.

This is a known issue specifically with the PDF, and we'll correct it in the next printing/next PDF update.

The full text for that feature is:

Hungry Growl (Wolf and Hybrid Form Only). The werewolf stares down and growls at one creature it can see within 30 feet of it. The target must succeed on a DC 13 WIS save or be frightened until the end of its next turn. The werewolf has advantage on the next attack roll it makes against the frightened creature.
