Diablo 2 Best Mercenary – D2 & D2R Merc Guide

Choosing the best Diablo 2 mercenary (or merc) for your character is a vital consideration in your ease of progression and often overlooked by the new player for just how powerful they can be particularly for the solo playthrough. With the right gear they can become a powerful ally against the armies of hell but before you can create the best merc build for them you’ll want to be starting with the right base.

The details below in regards to the Diablo 2 best merc setup are applicable for both Diablo 2 and Diablo 2: Resurrected (D2R) as the mechanics are unchanged between game versions. The Diablo 2 wiki on mercenaries is also an invaluable source for those that want the granular details and numbers of the below recommendation.

The Best Act To Hire Your Merc

Each act in Diablo 2 offers differently themed mercenaries that can be hired to fight for the player. When considering which act has the best mercenaries players need to consider what each offers in terms of abilities but also the type of weapons they can equip as this is fundamental in their power level.

Each act mercenary can be summarised as:

  • Act 1 (Rogues): Rogues hired from the first game act are restricted to using general bows and come with either cold or fire arrow and inner sight.
  • Act 2 (Desert Warriors): Melee fighters that can equip the various two handed spears, javelins and polearms and use the Jab skill. They also come with an aura that varies based on the difficulty and their specialisation that makes them the best D2 merc. Aura options are Prayer, Thorns, Defiance, Holy Freeze, Blessed Aim and Might.
  • Act 3 (Iron Wolves): Offering a spell caster option to Diablo 2 mercenaries the iron wolves specialise in fire (inferno and fireball), cold (glacial spike, ice blast and frozen armour) and lightning (charged bolt and lightning bolt). They can use shields and swords although rarely melee attack.
  • Act 4 (N/A): There are no Act 4 mercenaries in Diablo 2.
  • Act 5 (Barbarians): Allowing players to hire mighty melee warriors that can be equipped with Barbarian helms paired with a single sword. They come with Bash and Stun as abilities and are sometimes favoured for specific Diablo 2 builds due to runewords they have available and their better survivability.

diablo-2-merc-act-2Given the overwhelming power of the auras that the Act 2 mercenaries provide they are widely considered the best mercenary option and made only more useful by the powerful rune words you can make with their weapon class. The two most popular are Infinity for an additional Conviction aura and the budget Insight for Meditation aura although there are a host of other deadly damage dealing runewords available if you require neither of these.

diablo-2-merc-act-5Act 5 mercenaries are a viable alternative to Act 2 for those that want to experiment with something different or for specific builds. The Lawbringer runeword is a popular choice as it offers a Sanctuary aura to remove physical immunity while providing further utility with Decrepify and slain monsters rest in peace. All of this can be useful on characters with mostly physical damage, need a reliable tank to provide some crowd control or regularly farm undead areas and is most often seen on wind Druid builds.

The Best Act 2 Merc In Diablo 2

Choosing the best Act 2 merc is the hardest mercenary decision in Diablo 2 and often it comes down to your playstyle and build although there are a few clear winners to select from. The usages of each possible Act 2 mercenary is explored below and I’d encourage players to experiment with the available options before making a final decision.

For those that want a quick best to worst tier list of Act 2 mercs I would rate them as follows:

  1. Holy Freeze (best all rounder)
  2. Might (best for summon Necromancer and geared melee characters)
  3. Prayer (best for cold Sorceress and Insight mercs)
  4. Blessed Aim (useful for melee characters and niche mercenary builds)
  5. Defiance
  6. Thorns


Defiance (Defence Normal & Hell)

Provides a solid boost to your defensive statistics for both you, your mercenary and any summoned minions that improves survivability. While this concept might sound good in practice it’s actually one of the less desirable auras due to the way the aura and defence in general works in Diablo 2.

In brief defence reduces the chance of your character being hit from physical attacks, does not impact the damage you take, has diminishing effectiveness and is severely reduced when running. This combination of mechanics means that low defence characters like the Necromancer or Sorceress benefit little as they are likely to rarely be hit by physical attacks while characters with high defence values like the Paladin who fight in melee range already have sufficient defence that it is not a significant change in percentage chance to be hit.

Holy Freeze (Defence Nightmare)

The most popular of all Act 2 mercenaries for the majority of Diablo 2 character builds (but not all) and the one that many consider the Diablo 2 best merc due to the crowd control that the Holy Freeze aura provides. With this aura you’ll be able to easily run past enemies and slow them from attacking you passively that makes it useful in the vast majority of situations you’ll encounter. I also consider this to be the best merc for Hammerdin builds.

Blessed Aim (Offence Normal & Hell)

Blessed Aim can be a viable mercenary as you progress through the game for the melee fighter, particularly if you opt to rush through Diablo 2 quests and do little levelling given levels play such an important role in hitting enemies. Given the other normal mercenary options in Act 2 this is not a bad pick but beyond that is likely to be sub-optimal. The creative Diablo 2 community has made some unique mercenary builds with high crushing blow percentages and Blessed Aim to ensure your mercenary regularly hits their target as well.

Might (Offence Nightmare)

Without a doubt this is the Diablo 2 best merc for summon Necromancer as it can dramatically boost your skeleton damage with the aura active and when paired with your other spells like Amplify Damage is deadly. Might is also highly effective on well geared melee fighters that don’t need the other available auras here and want to boost their own damage or looking to make their mercenary into a deadly killing machine.

Prayer (Combat Normal & Hell)

For the player that likes to have their health regularly topped off with healing Prayer is actually quite effective when paired with an Insight that doubles the healing effect due to the way that Prayer and Meditation auras interact. I’ve constantly used Prayer on my cold Sorceress builds as I find the other options lacking with this build and I value the ability to completely disregard any small pieces of damage I pick up along the way when magic finding or progressing.

With this in mind I’d consider this one of the best merc for Sorceress (cold specialisation) although there are better options for most other builds. Note that Holy Freeze (discussed further below) still has some use for cold builds as it ignores immunity but the usefulness is severely reduced.

Thorns (Combat Nightmare)

While fun to experiment with on a summon Necromancer build as you watch demons hurt themselves on your skeletons and golem of choice this aura has the least uses of all your options and best avoided.
