Want to know the best Dota Underlords alliances to aim for with your next game? Synergies and alliances are vital for running an efficient and deadly Underlords crew, so knowing the most powerful alliance buffs is essential.

In case you’re unfamiliar with this new genre, here’s a brief recap. Dota Underlords is the latest autobattler to emerge after the impressive success of Dota Auto Chess – Underlords is Valve’s official version of the popular Dota 2 mod, except you can grab this for free as a standalone on PC, iOS, and Android.

There are a number of strategies you can employ in order to get the edge on your opponents, but you’ll need to be mindful of synergies and the best Dota Underlords alliances no matter which path you choose. You can tell what alliance a hero is by looking for a coloured icon below them, all heroes have two alliances and if you hover over the alliance icon you can see what bonuses are unlocked strengthening alliances. In normal view you can see what alliances you have by clicking on the top tab on the right-hand side of the screen.


While some alliances are stronger than others, some are also more common and will show up in early rounds, allowing you to build a very strong alliance over time rather than waiting until the last ten rounds to start thinking about synergies.

With 23 alliances to get through, here’s our Dota Underlords alliance tier list:

S tier


  • (2x) Knight units take 15% less physical and magic damage when standing 1 cell away from another knight
  • (4x) Knight units take 20% less physical and magic damage and an additional 20% when standing 1 cell away from another knight
  • (6x) Knight units take 30% less physical and magic damage and an additional 25% when standing 1 cell away from another knight

All of the buffs for this alliance revolve around keeping your Knight heroes together at all times, so they are naturally vulnerable to AoE damage and pure damage. With Mage heroes recently nerfed, the Knight comp is now one of the most effective in Dota Underlords. Most heroes in this Alliance also dish out meagre damage though, so work on getting as many upgrades as possible, not to mention some high DPS units like Sniper.


  • (3x) Elusive units gain +20% evasion
  • (6x) Elusive units gain +45% evasion
  • (9x) Elusive units gain +75% evasion

Not explicitly a defensive alliance, the Elusive alliance is, however, a great defensive synergy. The teamwide buffs give you a great chance of evading a lot of incoming melee damage. There is another perk from this, which is that missed attacks result in your enemy’s mana not restoring as quickly, which can halt combos dead. There are a lot of powerful Elusive heroes to pick from, making this a versatile, albeit tricky comp to run.


  • (3x) Warriors gain +10 armor
  • (6x) Warriors gain +15 armor
  • (9x) Warriors gain +25 armor

Many believe the Warrior to be the strongest defensive alliance in the game and it’s pretty easy to see why. For starters, it only takes a 3-stack of Warrior heroes to get a whopping armor buff across your whole team. This pairs nicely with healing and magic resist alliances like Scaled and Warlock, offering a very complete defense-oriented comp. If you’ve got space, Savage and Troll are also great to mix in due to their teamwide attack buffs.

Warlock alliance in dota underlords

A tier


  • (2x) Allies gain +15% lifesteal
  • (4x) Allies gain +30% lifesteal
  • (6x) Allies gain +50% lifesteal

Lifesteal is an incredibly potent trait that keeps all of your units in the battle for longer and will help you win any prolonged battles. This makes the Warlock alliance a very strong defensive setup to synergise an attack with and as it requires attacks to heal, you’re best off pairing it with an alliance like Troll, Hunter, or Assassin. The other benefit of Warlock is that you can activate the smallest bonus with just two heroes, making this a strategy you can mix and match with ease.


  • (3x) Assassins gain a 10% chance to critical hit for 300% damage
  • (6x) Assassins gain a 20% chance to critical hit for 400% damage
  • (9x) Assassins gain a 30% chance to critical hit for 500% damage

Critical hits don’t miss in Dota Underlords, making the Assassin alliance the only one capable of dealing with Elusive enemies. This alliance also allows you to leapfrog frontliners and great up positions, making this one of the best comps for dealing with the Knight, Ranged, or Mage alliances. However, this lethality only really hits its stride with the 9-stack bonus, leaving you with very few options for synergizing with other alliances.


  • (2x) Enemies suffer -5 armor
  • (4x) Enemies suffer -10 armor
  • (6x) Enemies suffer -20 armor

A very simple buff, but one that will make every stage of a match much easier for your heroes. On top of that, this is also a highly flexible alliance and you should find it easy to build up from heroes and comps you’re already establishing, such as in the Knight, Warrior, and Hunter alliances.


  • (2x) Allies gain +10% attack damage
  • (4x) Allies gain +25% attack damage
  • (6x) Allies gain +45% attack damage

A great alliance to synergise with a defensive comp, Savage heroes will offer a simple, but incredibly effective damage buff across your whole team. Pair with a low damage Alliance like Knight, Elusive, or Warrior. You also don’t need to chase the 9-stack Savage bonus as the first two reward tiers are both easy to attain and highly effective.


  • (3x) 20% chance of rapidly performing 2 attacks
  • (6x) 35% chance of rapidly performing 2 attacks

Squishy, yet very lethal: the Hunter alliance is formidable provided you have a defensive partnership to keep them alive. You’ll also need to watch out for a rival Assassin alliance as this build quickly falls apart if the enemy can circumvent your frontliners. Expect a very strong synergy with Heartless, Scaled, and Elusive alliances – the three-stack bonus should be all you need to make this comp work.

B tier


  • (1x) – Demon units gain +50% pure damage. Active when you have only one type of Demon unit on the board

It’s hard to really slate the Demon alliance, except for by pointing out that it’s not much of an alliance. The second you add another Demon to your board you lose out on a neat +50% pure damage buff. The upside of this, you only need a single hero for this Alliance, and each of the four heroes are individually strong and fit seamlessly into other comps. For example, Shadow Fiend slots into Mage, Chaos Knight into Knight, Queen of Pain in Assassins, and Doom is a Warrior.


  • (2x) When hit, Primordial units have a 30% chance to disarm melee attackers for 4 seconds
  • (4x) When hit, allies units have a 30% chance to disarm melee attackers for 4 seconds

There’s a fair amount of luck involved with this alliance, but if you’re able to tie it to another strong alliance and get one or two disarms off on high DPS enemies then you’ll find it incredibly handy. This works especially well if you’re going after a 9x Warrior bonus as this comp occasionally suffers from


  • (2x) Human units gain a 20% Chance to silence target for 4 seconds when attacking.
  • (4x) Human units gain a 44% Chance to silence target for 4 seconds when attacking.
  • (6x) Human units gain a 66% Chance to silence target for 4 seconds when attacking.

Lots of heroes from the Mage, Knight, and Warrior alliance also belong to the Human alliance so you’ll manage to accrue a set bonus pretty easily with this comp. The benefits are tricky to notice in most cases, but can make a huge difference in the late game where stopping an enemy from casting can give your team the edge, especially if it’s a Tidehunter.


  • (2x) Allies gain +30% magic resistance
  • (4x) Allies gain +50% magic resistance

A very powerful alliance to form if you notice other teams gearing up for mage comps. The effect is easy to trigger with only a 4-stack needed, and the effects spread to all allies as soon as you have two Scaled heroes on the board, and if you just want two of these then Tidehunter is easily one of the best standalone heroes in Underlords (Medusa’s not bad either).


  • (2x) Troll units gain +35 attack speed
  • (4x) Troll units gain +65 attack speed and other allies gain +30 Attack Speed

In terms of raw damage, you can’t get much better than the Troll alliance. With a 4-stack bonus your crew’s DPS will go through the roof. Pair these guys with the low-damage Knight alliance for a solid melee crew, while pairing with Warlock will mean a high healing rate via Lifesteal. The only real threat to a good Troll comp is an Elusive stack.

C tier


  • (2x) Unlocks an additional ability for each member of the Alliance

As a pretty small alliance of just two, this is a great way to flesh out a Knight comp, which maxes out with nine heroes. All three heroes in this alliance are very strong, but there’s a powerful strategy in which a Dragon Knight is placed behind frontliner Knights in order to keep this high damage unit in the fight for as long as possible.


  • (3x) A Random ally is granted +15 Armor and +10 HP Regeneration
  • (6x) Allies gain +15 Armor and +10 HP Regeneration

There’s a lot of crossover with the Inventor alliance due to the unit pool, but if you can unlock the 6x alliance reward then Scrappy can be used in late game as well as early on. You may struggle to get a 5-cost Techie into your roster, but if you can then pairing this Alliance with either high magic resist or lifesteal can you give you great results.


  • (3x) Enemies suffer -40% Magic Resistance
  • (6x) Enemies suffer -100% Magic Resistance

With seven different Mage aligned heroes, there’s plenty of choice here, but the Alliance bonus isn’t particularly strong unless you can weave in some more damaging spell-slingers outside of the Mage alliance: Shadow Fiend and Disrupter both dish out high splash damage. However, this comp can fall apart when coming up against any heroes with magic resist or immunity items.

Demon Hunter

  • (1x) Invalidate your opponent’s Demon alliance bonus
  • (2x) Invalidate your opponent’s Demon alliance bonus. Demon units gain +50% pure damage

The Demon and Demon Hunter synergy is pretty strong, but it’s also very demanding leaving little room for any other alliances. The two heroes from the Demon Hunter Alliance, Anti-Mage and Terrorblade, are both fine heroes on their own, so together with some Demon heroes backing them up, this can be a solid Underlords build.


  • (2x) Deadeye units focus their attacks on the lowest-health enemy
    This is a strong alliance if you can get it on the board, however as

Gyrocopter is a 5-cost unit that isn’t something you can bank on. If you’re running a Hunter comp, however, should you stumble across a Gyrocopter then snap it up fast as these snipers are great for finishing off low-health targets and can have a huge impact in close rounds. With only two heroes, you can’t build a team out of this alliance, but as an addition to a comp they’re pretty handy.


  • (2x) All Brawny units have their maximum HP increased by 200
  • (4x) All Brawny units have their maximum HP increased by 500

Great against mages all the way through the match because of their high health pool, these solid frontliners are great in the early and mid game, but simply can’t keep up when high damage enemies start appearing.

D tier


  • (2x) The lowest star ally druid is upgraded a level
  • (4x) The 2 lowest star ally druid is upgraded a level each

If you can upgrade your early game druids fairly quickly then this Alliance is pretty strong all the way up to late game. However, aside from Treant Protector and Lone Druid, the other heroes in this pool are weak as individuals, making this a supplementary alliance rather than one you want to build your comp around.


  • (2x) Inventors gain +15 HP Regeneration
  • (4x) Inventors gain +40 HP Regeneration

The best of a bad bunch, the Inventor alliance absolutely dominates early on and contains a couple of low-cost heroes making it easy to get a few upgraded heroes into your comp. However, this Alliance is weak as you approach the end of the game, with the HP regeneration nowhere near enough to help deal with high damage enemies.


  • (3x) A random enemy is turned into a frog for six seconds at the start of a round

Great for limiting your opponents initial DPS, but as it’s random results can vary wildly. With only one tier reward and three heroes needed to activate it, the Shaman alliance is currently weak and tough to work into a comp.


  • (2x) When a Blood-bound unit dies, all other Blood-bound units +100% attack damage for the rest of the battle

With only two Dota Underlords hero carrying this alliance and only one tier to the alliance, there’s really not much to be gained by opting for this alliance and no way to build a comp around it.
