Up until now, Diablo 4 has been missing out on one of the series’ past features that would give players the ability to have a companion along to help in the fight to save Sanctuary. Now, four new mercenaries from the Pale Hand are available to unlock in the Vessel of Hatred expansion with unique lore and quests behind them. Each one has specific abilities, which can be leveled up as they accompany the Wanderer across Nahantu, and can even bring valuable rewards.
