Keep this card. Starting next round, a player may use this when they fight a Beast as part of a Hunt Action. It cancels 1 Wound suffered by the player. The effect can only be used by one player per round, but that player can use it multiple times.
The Helmet can also be used to cancel one Wound suffered as the result of the red (Hungry Animals) die. In this case, if the Helmet has already been used in a Hunt Action earlier in the round, then only the player who used it has their Wound cancelled. If it has not yet been used, you must choose which player has their Wound cancelled.
