Hiring mercenaries is one of coolest new features in Diablo 4's Vessel of Hatred expansion, letting you recruit a famed fighter you can bring into battle with you. These warriors have their own ability tree, granting passive effects, and specialising in either buffing certain stats or applying debuffs to enemies. All in all, they make a big impact in combat.
There are four mercs to recruit in Vessel of Hatred, each of which has a specific fighting style, but if you can't decide on one, you can also bring a second as a reinforcement you call upon for one-off hit and run attacks. Here I'll list my personal pick for the best merc, how to unlock them, plus how they work. I've also included a list of all mercs plus their specialisms and unlock conditions down below.
