Time to pull up those socks, because during the “Grind It Out!” bonus event, from 07/01/2021 to 13/01/2021, there are cool Surprise Boxes at the Second Hand Shop. The boxes each include one item from the unique “Grind It Out!” item set as well as another epic item.
On top of that, you’ll get a nice little boost to your experience bar during the bonus days. So get moving!
your Hero Zero Team.
