The Diablo 4 Potent Vows objective in Diablo 4 Gold this season's Journey is a bit buggy and might not be working for you

There will always be one Blood Harvest area on the Diablo 4 map marked in blue. Every Blood Harvest lasts for one hour, so travel to the marked area and get stabbing. Each monster you kill has a chance to give you +1 Hunter's Acclaim, which gets added to your total at the board. Although there are a few other ways of getting Hunter's Acclaim which I'll cover further down.

You can head back to the Hunter's Acclaim board in any major town to check on your progress and collect any rewards from the tiers you've completed. Obviously, Tier 9 will take a while to reach but the Accursed Touch is a great Diablo 4 Vampiric Power to have, giving you a chance to inflict Vampiric Curses on enemies that can spread and store the souls of their victims for later attacks. Beyond Tier 9, you'll get all sorts of Legendary rewards, such as armor pieces, weapons, and reward caches.
