The calldowns for Alarak, at level 15, with no mastery points added are:

Calldown Name Description Recommended Usage Numbers
Structure Overcharge Structure Overcharge Energizes target friendly structure or War Prism in Phasing Mode, allowing it to attack nearby enemy ground and air units.
  • Use the first overcharge to clear out rocks and contested expansions.
  • Use overcharges to add extra DPS when pushing and defending against attack waves.
  • Overcharges can also be used to destroy objective structures during the early game, while you get higher tech units out.
  • Lasts 45 seconds.
  • Coolup: 90 seconds
  • Cooldown: 90 seconds
  • Max Charges: 3
  • Damage: 40
  • Range: 10
  • Atk Spd: 0.641
Summon Death Fleet Summon Death Fleet Warps in a Tal'Darim Mothership and 8 Destroyers that are controllable and will fight for 60 seconds.
  • Useful for adding extra DPS to pushes and defending attack strong attack waves.
  • Use the Mothership's Mass Teleport ability to give your army extra mobility.
  • If using the Shadow of Death prestige, the calldown costs 400/400, with each Destroyer costing 125/75.
  • Coolup: 600 seconds
  • Cooldown: 360 seconds

The Summon Death Fleet ability brings a Tal'Darim Mothership onto the battlefield. This unit has abilities itself, shown below:



Ability Name Description Cooldown
Thermal Lance Thermal Lance Deals 20 damage to all enemies in a straight line up to 10 range away. 1 second
Mass Teleport Mass Teleport Teleports the Mothership and all nearby units you control to target friendly unit or structure's location. 0 seconds*

The Summon Death Fleet ability also brings Destroyers onto the battlefield. They do not have abilities or upgrades. Additionally, their bounce damage is not affected by attack upgrades.



*If using the Shadow of Death prestige, this cooldown is increased to 60s, and no longer teleports allied units.

Sub-Ascension Leveling

Difficulty: Moderate

Use a Slayer/Supplicant build as your main attack force. Use Alarak's Destruction Wave ability to push enemy units away from your army. Additionally, ensure you have a War Prism which you can Overcharge to provide you with additional DPS when pushing into enemy bases. Clear your expansion with two Overcharges.

While leveling through Mastery levels, allocate points into Power Set 3's Structure Overcharge mastery until you hit the desired number of points, before allocating them to Chrono Boost efficiency.


Below are the three Power Sets for Alarak with the recommended point allocations for each. Note that these are meant to serve a general, all-purpose build that is effective across all maps with no Prestiges selected. You are highly encourged to change these masteries to suit your playstyle and particular challenges you face (e.g. Weekly Mutations).

Power Set 1:

Power Value Recommended Points to Add Further Considerations
Alarak Attack Damage 1 per point
30 maximum
? The choice here mostly depends on how you use Alarak and if you prefer to use skill-based units (like Ascendants) or attack-based units (like Wrathwalkers).
Combat Unit Attack Speed 0.5% per point
15% maximum

If you are working with an Ascendant-based build, Alarak Attack Damage is recommended as Ascendants do not benefit much from the other mastery.

Power Set 2:

Power Value Recommended Points to Add Further Considerations
Empower Me Duration 1 sec per point
30 sec maximum
? Empower Me Duration can provide a lot of mileage for mastery points, especially when used with the No Cooldown Alarak technique. However, it does require a significantly higher level of mechanical ability.
Death Fleet Cooldown -4 sec per point
-120 sec maximum

This is a personal preference. Those that use the No Cooldown Alarak technique (below) may want to consider putting all points into Empower Me Duration instead.

Power Set 3:

Power Value Recommended Points to Add Further Considerations
Structure Overcharge Shield and Attack Speed 2% per point
60% maximum
22 Players that prefer to use Structure Overcharges more offensively can choose to add more points into that respective mastery. It is generally not recommended to go below 22 points, as it will prevent the Structure Overcharge from clearing expansions.
Chrono Boost Efficiency 1% per point
30% maximum

The 22 points into the first mastery is just enough to clear both, the main and the gas rocks at your expansion. The rest are put into Chrono Boost.


Below are the prestiges for Alarak. Note that "Effective Level" is the level at which the prestige achieves it full effect.

Level Name Description Effective Level Notes
1 Artificer of Souls
  • Advantages:
    • When a supplicant dies, it increases the damage and attack speed of one of Alarak's nearby non-heroic mechanical combat units.
  • Disadvantages:
    • Deadly Charge and Destruction Wave damage reduced by 50%.
  • Stacks get applied within 15 range.
  • Each stack adds 10% damage and attack speed
  • Slayers and War Prisms get two stacks per Supplicant
  • Maximum stack count is 10.
This prestige adds further utility to Supplicant deaths by allowing them to buff Alarak's mech units. This does mean that Alarak cannot 1-shot Zergling waves by using Destruction Wave. However, adding Ascendants to deal with attack waves is very beneficial anyway, as Supplicants can be sacrificed for Power Overwhelming stacks as well as buffing Mech units.

Level Name Description Effective Level Notes
2 Tyrant Ascendant
  • Advantages:
    • Empower Me cooldown reduced by 50%.
  • Disadvantages:
    • The Death Fleet is unavailable.
5 None
This prestige sacrifices Alarak's mobility from his Death Fleet to add extra power to Alarak pushes by making his Empower Me more frequent. Death Fleet damage is not considered due to its relatively low damage compared to Alarak's units. For players that are aware of mission timings, they will very rarely get caught unawares, and combined with the No Cooldown Alarak technique, this prestige can be very valuable.

Level Name Description Effective Level Notes
3 Shadow of Death
  • Advantages:
    • Summon Death Fleet has no duration or initial cooldown. The Mothership may construct Destroyers.
  • Disadvantages:
    • Destroyers are no longer summoned with the Mothership.
    • The Mothership and Destroyers have resource and Supply Costs.
    • Mass Teleport now has a 60 second cooldown and no longer teleports allied units.
  • Mothership costs 400/400.
  • Each Destroyer costs 125/75.
  • Mothership and Destroyers are unaffected by Unit Attack Speed mastery.
  • Destroyer bounce damage is unaffected by attack upgrades.
A trap in using this prestige is using it to mass up a large fleet of air units. Because Destroyers deal small amounts of damage with a high attack speed, they are heavily weakened by armored targets, especially considering that bounces are unaffected by Attack upgrades. They are also susceptible to splash damage, like Parasitic Bombs. A better utility for this prestige would be to invest in the initial Mothership for a big early-game power spike, and then use the Mothership as a mobility tool throughout the course of the mission.

Depending on the player's prefered playstyle, Artificer of Souls or Tyrant Ascendant both offer Alarak potential power level increases to their respective playstyles. Those two prestiges are recommended for general play.

Hero Unit


Spawn time: 4:00

Respawn time: 1:00

The abilities for Alarak are:

Ability Name Description Cooldown
Deadly Charge Deadly Charge Alarak intercepts target enemy unit and strikes it for 200 damage. 10 seconds
Destruction Wave Destruction Wave Unleashes a massive wave of force in a straight line, dealing 50 damage to enemies in its path and knocking them back. 5 seconds
Empower Me Empower Me Alarak's attacks and abilities deal increased damage for each allied unit nearby. Mechanical units grant him double the power. Resets the cooldown of Deadly Charge and Destruction Wave.

Biological units provide a 5% damage bonus per supply up to 100 supply, and then provide 2.5% per supply onwards. Mechanical units provide 10% damage bonus per supply up to 100 supply, and then provide 5% per supply onwards.

Supply count is additive, with biological units favored first. So if you have 100 supply in bio and 1 supply in mechanical units, the mechanical units will provide the reduced rate of 5%.
240 seconds

The upgrades for Alarak are:

Upgrade Name Effect Minerals/Gas Research Time
Imposing Presence Imposing Presence Allows Alarak's attacks to stun enemy units for 2 seconds.

Heroic units are slowed.
150/150 90 seconds
Telekinesis Telekinesis Increases the knockback distance of Alarak's Destruction Wave by 100%. 150/150 90 seconds

Recommended Army Composition

The recommended army composition for Alarak is below. Note that this assumes no Prestige talent selected and recommended Mastery Allocations. This is a basic recommendation for your army framework. It is recommended to gain an understanding for each of the units in the Units section and further add tech units so that you are able to better handle the situations you face.


Ascendants, with the Power Overwhelming upgrades, can deal extremely large amounts of damage to units, allowing Alarak to handle attack waves and unit-based objectives with ease. Supplicants are required for Alarak's Empower Me as well as keeping Ascendants filled with energy through Sacrifice.


Add Wrathwalkers to your army composition if you are dealing with objectives that are structures.


Add Vanguards to your army if you need extra damage sustain and splash damage.

Gameplay Guide

Playstyle Traps

A possible playstyle trap is to focus on building a mass of Supplicants without adding any other tech units. While Supplicants are used to keep Alarak alive, and massing a large number increases Alarak's power when he uses Empower Me, Supplicants do not have a high DPS by themselves. Specific tech units (Ascendants, Wrathwalkers, etc.) will be needed to further improve a player's performance in the mission.

Fast Expanding

One of the perks of playing Alarak is his ability to fast-expand, even on contested maps. While other commanders will need to wait for their hero unit to spawn, or make an army to clear contested expansions, Alarak can use a probe with an overcharged pylon to clear contested expansions.

Below are pictures that show how to fast-expand on maps. These require a lot of practice to pull off, but can put you ahead economically. It is also advisable to fast-expand with two probes, one as a backup in case you lose the first one to prevent you from wasting an overcharge. You will be using these probes to get vision for the Overcharge.

Map Race Player 1 Expansion Player 2 Expansion
Chain of Ascension

Player 1 Fast Expand on Chain of Ascension
Player 2 Fast Expand on Chain of Ascension
Cradle of Death Extremely difficult to fast-expand. The general idea is to place a Pylon and overcharge it to clear enemy defenders. Once the defenders are cleared, the Pylon needs to be cancelled before it is complete. Two overcharges are required.
Dead of Night No contested expansion
Lock & Load No contested expansion

Player 1 Fast Expand on Malwarfare
Player 2 Fast Expand on Malwarfare
Miner Evacuation Race doesn't affect Expansion
Player 1 Fast Expand on Miner Evacuation
Player 2 Fast Expand on Miner Evacuation
Mist Opportunities No contested expansion
Oblivion Express No contested expansion
Part & Parcel*

Fast Expand on Part & Parcel
Rifts to Korhal No contested expansion
Scythe of Amon** Race doesn't affect Expansion
Fast Expand on Scythe of Amon
Temple of the Past No contested expansion
The Vermillion Problem

Fast Expand on The Vermillion Problem
Void Launch No contested expansion
Void Thrashing No contested expansion

* Zerg has been intentionally omitted from Part & Parcel due to the inconsistency in fast-expanding. This is due to a number of reasons:

** Fast-expanding on Scythe of Amon means you have to clear the Sliver at the expansion. This is because of the Void Rift that will keep spawning units. Destroying the Void Rift does not solve the problem as it will respawn unless the Sliver is destroyed. You will need two Overcharges to destroy the first Sliver and any units nearby.

No Cooldown Alarak

The "No Cooldown Alarak" technique takes advantage of the "Wrath of the Highlord" upgrade for Alarak. Whenver a Supplicant is sacrificed (either to Alarak or an Ascendant), Alarak's abilities are reset off cooldown allowing him to spam his abilities repeatedly. Combined with Empower Me, this can completely devastate enemy camps and hard-to-push locations.

This technique is sometimes called the "1qe2c" technique, named after the hotkeys assigned to Alarak (1) and his Ascendants + Supplicants (2). The cycle is as follows:

Below is an example of what the technique looks like.

No Cooldown Alarak

The above technique is quite difficult to master and requires a lot of practice, but you can see its power when dealing with the attack wave. By targeting a high-HP unit with Q, you can not only deal damage to it, but also push it back along with the rest of the attack wave.

Note: This technique only works due to the Wrath of the Highlord buff you receive at Commander Level 15. Additionally, this buff only applies within 15 range. The below picture gives you an example of the maximum distance this can be used.

Wrath of the Highlord Range

In the picture above, the Ascendants are at roughly the maximum possible range to allow for Alarak's skill cooldowns to be reset from Wrath of the Highlord.

A detailed video of this technique is shown below
