Diablo 2 Best Mercenary – D2 Merc Guide

Diablo 2 Best Mercenary – D2 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 D2 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. This base factors in hiring your mercenary from the right story act and with the right speciality for your objectives.

The details below in regards to the Diablo 2 mercenary setup are applicable for both Diablo 2: Lord of Destruction (D2) and Diablo 2: Resurrected (D2R) as the core mechanics are unchanged between game versions. Note that patch 2.4 for D2R in April 2022 provided a significant overhaul to the mercenary mechanic and generally provided buffs and additional offensive options to these AI companions which are noted throughout this guide where relevant. The Diablo 2 wiki on mercenaries is also an invaluable source for those that want the granular details and numbers of the below recommendations that are explored below at a summary level in this D2 merc guide. At the end of this guide I’ll also cover some of the best merc armour, best mercenary weapons and runewords for mercenaries to ensure your companion is appropriately equipped for battle.

Diablo 2 Mercenaries – Different In Each Act

Like many other games like Diablo players can recruit an AI controlled ally to fight alongside them. In Diablo 2 specifically each act offers different themed mercenaries that can be hired to fight for the player and come with their own strengths. 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. Note that prior to the Diablo 2: Lord of Destruction expansion players could not equip their hirelings with items and with this game mechanic added players can now significantly boost the damage of their mercenary companions.

The Diablo 2 mercenaries from each act can be summarised as follows:

  • 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 for their abilities. Players earn one for free after defeating Blood Raven which is generally your first experience with mercenaries. In D2R these mercenaries can equip Amazon bows, benefit from + Amazon skill levels and enhance their arrows further with freezing arrow and explosion arrow.
  • 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 for the vast majority of situations. 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 (or firebolt in D2R), fireball and enchant in D2R), cold (glacial spike, ice blast and frozen armour (or chilling armour in D2R)) and lightning (charged bolt, lightning bolt and static field in D2R). 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 can equip and their better survivability. In D2R these mercenaries now benefit from +Barbarian skill bonuses and are split between a dual wielding and two-handed variant that offer different specialties in skills. For dual wielding they have access to frenzy, taunt and iron skin abilities while the two-handed hire has bash, stun and battle cry.

diablo-2-resurrected-act-2-merc-hireGiven the overwhelming power of the auras that the Act 2 mercenaries provide they are widely considered the Diablo 2 best merc 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 the Conviction aura (to reduce enemy resistance) and the budget Insight for the Meditation aura (mana recovery) although there are a host of other deadly damage dealing high level runewords available if you require neither of these. While the D2R mercenary rework patch of 2.4 did allow for some of these powerful runewords to be made in new weapon bases the inherent aura of these mercenary options is simply too powerful to look past.

diablo-2-merc-act-2

Act 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 the rare 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. With the D2R changes giving these fighters some Barbarian shouts their utility is one of the best after the Act 2 variants.

The Best Act 2 Merc In Diablo 2

With the options laid out your decision for Diablo 2 AI partner quickly becomes limited to an Act 2 mercenary hired from Greiz in Lut Gholein. Choosing the best Act 2 merc for you is thus the main mercenary decision that you’ll make in Diablo 2 and often comes down to your playstyle and class build although there are a few clear winners to select from. The usages of each possible Act 2 mercenary is explored below in a mini Act 2 merc guide and I’d encourage players to experiment with the available options before making a final decision (don’t forget to unequip any gear you have on your current hireling before hiring a new one).

diablo-2-resurrected-mercenary-skills

The Act 2 merc auras are as follows, note that in Diablo 2: Resurrected the mercenary types of Combat, Defence and Offence are no longer used from the original Diablo 2 and you can mouse over the skill icons next to their level to see what aura the mercenary has. Note that in D2R players can hire any of these auras in Nightmare and Hell and are no longer act restricted.

  • Prayer – Combat (Normal or Hell)
  • Thorns – Combat (Nightmare)
  • Defiance – Defence (Normal or Hell)
  • Holy Freeze – Defence (Nightmare)
  • Blessed Aim – Offence (Normal and Hell)
  • Might – Offence (Nightmare)

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

  1. Holy Freeze (best all rounder)
  2. Might (best for summon Necromancer and geared melee characters looking for more raw damage)
  3. Prayer (Great for well geared late game cold Sorceress and others that use Insight mercs and want some health regeneration but don’t need the Holy Freeze crowd control)
  4. Blessed Aim (useful for melee characters in specific situations and niche mercenary builds)
  5. Defiance (not used)
  6. Thorns (not used)

Each of these D2 Act 2 merc auras is explored in further detail (in order) below.
diablo-2-mercenary-inventory

Holy Freeze (Defence Nightmare)

The most popular of all Act 2 mercenary auras 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 once you have enough mana sustain gear. Even a cold based sorceress can benefit from this mercenary option as Holy Freeze can still impact cold immune monsters giving you additional survivability from your biggest threat.

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 in their own right with the correct gear. Beyond these specific circumstances though Might is rarely going to be your first pick.

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 runeword that doubles the healing effect due to the way that Prayer and Meditation auras interact. I’ve constantly used Prayer on my late game cold Sorceress builds as I find the other options lacking with this build once fully geared and I value the ability to completely disregard any small pieces of damage I pick up along the way when magic finding.

Prayer is also the best mercenary aura available for normal for most players and can definitely save you on health potion usage and trips back to town. Don’t get too attached though as you’ll likely replace them in Nightmare with a Holy Freeze mercenary (unequip any gear you have given them first).

With this in mind I’d consider this one of the best merc for Sorceress (cold specialisation) when you reach your final build for magic find runs although Holy Freeze is generally a better option during your path there and most other class 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 difficulty 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 for those that want to try these out although they are niche off meta choices used for the sake of doing something different more so than anything.

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 especially when factoring the loss of a better aura option.

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 unless you are looking to experiment for fun or variety and not recommended for use in this Diablo 2 mercenary guide.

Best Mercenary Gear

While choosing the correct mercenary is important equipping them with appropriate gear should never be overlooked and in fact required if you expect your Act 2 mercenary to survive for longer than a few minutes. The below equipment guide to your mercenary is focused solely on the Act 2 mercenary although some parts will be applicable to other mercenary types you might be experimenting with.

At the core you are looking to achieve the following from the limited equipment slots (weapon, helmet and armour) that your mercenary can equip. The below includes the best mercenary armour, best mercenary weapon and mercenaries runewords to consider when building your ally.

  • Lifesteal: In order to keep your mercenary alive you’ll need a reliable source of lifesteal which allows them to heal themselves from damage dealt. Note that you will need to equip them with a decent weapon to maximise the life gained from attacks though. The helm slot is generally utilised to obtain this lifesteal with options like Tal Rasha’s Horadric Crest, Crown of Thieves, Vampire Gaze and Andariel’s Visage being popular as they also provide an abundance of other useful stats and are often considered the best merc armour options in D2. Less popular but still useful alternatives for obtaining life stolen per hit include Undead Crown, Wormskull, Stealskull, The Reaper’s Toll and Bonehew.
  • Resistance and Defence: Just like the player a lack of resistances can quickly take a mercenary from full health to zero so you should always seek to have these at the maximum possible (75%) or close to it although needs to be balanced alongside other mercenary needs. Thankfully mercenaries do gain some all resistance for each level so you don’t need a significant investment here at the higher character levels. Fortitude is often considered the best mercenary armour in this regard giving you some all resistance (+25) alongside a great boost to damage and defence. Similarly Treachery can be a budget armour option which again provides a balance of defence (through Fade) and damage boosting stats (attack speed and Venom). Other possible options include Shaftstop, Smoke and Duriel’s Shell which all come with decent defence stats as well.
  • Damage: Maximising damage is an important step to ensuring that you benefit from the life stolen per hit that you are equipping your mercenary with. Popular options for the best mercenary weapon include Insight and Infinity runewords as they come with great damage while also providing invaluable utility which makes them ideal mercenary runewords. Players can also utilise mercenary weapons like Bonehew, Tomb Reaver, The Reaper’s Toll, Obedience to maximise raw damage from the mercenary with ethereal weapons particularly useful as they have enhanced damage and durability is not used when equipment is used by mercenaries.

  2. I try use cold mercenary on hell but not let me chose

    • If you are looking for an Act 2 cold mercenary (with Holy Freeze) these are only available in Nightmare so you’ll have to go back there to hire one.

  3. Interesting guide, but of limited use to starting players as none of the recommended gear and runes are available in normal mode.

    • Hi Joe

      For Normal follow the principles of gear recommendations as closely as possible (lifesteal, resistance and damage). For Normal this generally means you’ll be using a rare (yellow) polearm with lifesteal on it if you can find one and whatever is the best armour and helmet you pick up along the way. The min-max options here really only become required in Nightmare and Hell to ensure they survive long enough to be useful.

      • Any changes to recommendations for v 1.07 players?

        • Hi SS,

          I assume you’re talking about pre Lord of Destruction as that was the patch before the expansion release. In this case unfortunately mercenaries are simply not useful and there is little you can do to counter that as the ability to equip items is core to their strength.

          Act 2 mercenaries would still be my recommendation (Prayer in Normal and Holy Freeze from Nightmare onwards) but they will likely die often and generally aren’t worth the trouble.

  4. Hi! I’m currently running through Hell difficulty and am having problems with my mercenary dying repeatedly in Act IV. He’s a level 80 Desert Holy Freeze Merc with an Insight, Griswold’s Heart (mainly for the massive defense buff) and a yellow helmet that gives 10% hit recovery with 70% boost to defense.

    I’m struggling with him. Mind offering advice on how to gear him so he won’t die in two seconds in Act IV? Thanks!

    Oh, I’m playing a Blessed Hammer Paladin – if you needed to know.

    Thanks!!

    • Hi Logan

      The key thing you are missing is a source of lifesteal as this allows the mercenary to self sustain themselves. The helm is a good spot to get this and requires an item like Tal Rasha’s Horadric Crest, Crown of Thieves, Vampire Gaze and Andariel’s Visage. Ideally your Insight would also be made in a Hell Elite polearm for the large attack to make this lifesteal effective.

      Trading for or hunting these helms is your best bet. For hunting Tal Rasha’s Horadric Crest is quite a common set item in the scheme of things with the best chances from Nightmare Diablo, Mephisto and Baal. While in Hell Diablo, Mephisto and Andariel also have decent drop chance.

      You may also want to just check the resistances of your mercenary although at level 80 these are probably okay. Some of the helms (like Tal Rasha’s) also helps with resistances.

      As a blessed hammer Paladin you could also likely push through the rest of the game without the mercenary and just drink lots of potions to replace the loss of Insight runeword if you wanted to.
