Best 2–4 Player Class Combinations and Aura Synergies in Diablo 2?

I’m looking for ideas for strong 2-player, 3-player, and 4-player team compositions in Diablo 2.

I’m particularly interested in setups where the characters are built to support each other, not just four random strong solo builds.

Examples:

Multiple Paladins using different auras
Necromancer + Paladin for curses, summons, and aura support
Sorceress with

Enchant supporting melee characters or summons
Paladin aura combinations that boost the whole group

Which class combinations create the strongest synergies for damage, survivability, leveling, and farming?

I haven’t found much detailed information about this, so I’d appreciate practical examples and explanations.

A good 4 player setup would be:

1.

Fanaticism Paladin (maybe with a merc wearing Pride for

Concentration Aura).

2. Any physical damage Barb with

Shout+BC+BO

3.

Poison Nova or

Bone Spear Necro with Curses and

Corpse Explosion

4. Warlock for Sigils and Hexes or a Sorc for

Static Field and elemental damage support for phys immunes


Of course there could also be 4 Fire Warlocks with 4 Apocalypses at once. I mean, why not All four could be naked and they would beat the game (easily).

For a duo, you should probably go for two different kinds of damage (maybe one physical and one elemental or two different elements or one element and one magic etc) so that you can deal with immune or sundered or high resistance monsters better. Then basically any combination of two viable builds that can also finish the game solo should work.
If you want a challenge: A

Poison Dagger Necro and an

Inferno-

Blaze-Sorc

1. FoH-Paladin or Tesladin providing

Conviction paired with any elemental caster class is a great combo to maximize damage output. By the way, a party-oriented FoH-build is the best healer in the game. With maxed

Prayer, he can cast Holy Bolts healing up to 2k life per second to your frontliner!

2. Fanazealot pairs well with Bowazons, Javazons or Trapsins/Bladesins. He is a formidable tank, helps greatly with IAS and makes life of the sensitive sisters much easier. A Throw-Barb can swap his Faith-merc for something more useful and offers defensive buffs for the Paladin to improve his tankyness.

3. Summoner/Defiler Warlock + ES Warlock is a sick duo. The Summoner brings a strong tank and multiplies ES damage from fellow Warlock. Add Might merc, one

Prayer/Cure/Insight merc,

Fanaticism/Cursed demon,

Concentration/Cursed demon. That's six auras! Add a Summoner Druid for another damage aura, even more hard-hitting minions and steady

Shock Wave security for any situation. Accompagnied by a Harmony-Rogue Scout. I can tell, this team is invincible.

4. A Fishymancer brings a lot of safety, crowd control and damage to the party. His huge army makes fighting Heralds a walk in the park! Dangerous

Thorns can be countered with

Life Tap, hellish Wisps or Dolls with

Dim Vision. He pairs well with all ranged or melee classes and can provide up to 5 auras at once!

5. Barbarian and Sorceress are always a perfect team. The

Whirlwind- or

Frenzy-Barb is a good tank, improves survival capability of the Sorc and the Sorc... yeah, she does Sorc stuff like roasting the screen. Even if not using Enigma, the Barb can cross rivers and rifts with his

Leap skills to keep up with his partner which makes them a nice duo for levelling. Endgame Barbs can go

Find Item, so the Sorc can maximize her damage potential.

6. The Poisonmancer can fulfill a similar role as FoHdin/Tesladin. He can provide meatshields or bonewalls to counter aggressive Heralds and pushes party damage with

Lower Resist while casting poison spells and

Corpse Explosion.

7. The Enchantress is a well-known support build for any physical damage class. The more attacks, the stronger. Imagine an Armymancer with 30+ enchanted minions, each of which dealing +4k fire damage. Or think of a Multishot/Strafezon. Any melee class will love her for the huge AR boost. Give her a

Demon Machine, so she doesn't get bored.
