The Archon is a powerful Protoss short-range unit. It excels against biological units and structures. An Archon is created when two of either Dark Templar or High Templar merge together on the battlefield; the Archon cannot be produced at any building. Archons can attack air or ground units and deal area-of-effect damage. Archons' tremendous shield points can withstand terrible punishment, offsetting their exceptionally low health: an Archon has only ten health points beneath its shield.

Archons have very few attributes; they are considered Massive and Psionic. Bonuses against massive units only apply to air targets (and Graviton Beam can't target massive units), and Legacy of the Void has no bonuses against Psionic units (Snipe was removed). As such, the Archon is an effective all-rounder unit - apart from Ghosts, who can use EMP Rounds to tear through their shields, there is no one unit that works especially well against the Archon.


Archons have three possible mineral/gas costs, depending on how they are created.

  • + = Minerals 100 Vespene Gas 300
  • + = Minerals 175 Vespene Gas 275
  • + = Minerals 250 Vespene Gas 250

Competitive Usage[edit]


Archons primarily function as support units. Because they have a range of 3, Archons can sit safely behind a line of Zealots and deal damage to the enemy forces without taking much damage. Because Protoss shields regenerate rapidly out of combat, Archons are much more effective if they pull out of battle before they die.

Archons cannot be commanded as they merge, but they can be bumped around like big psionic soccer balls by moving units into them. Morphing Archons can be moved behind the army as protection, or taken to retreat with the rest of the army.

Archons are often used as part of or against a timing push. They are a Protoss player's quickest access to area of effect damage. The Colossi and High Templar require some time to reach their potential. Colossi require a Robotics Bay in addition to the Colossus itself, whereas a High Templar's Psionic Storm costs 75 energy and must be researched.

Archons are massive units; ergo, they crush Force Fields on contact. This makes them especially useful in PvP timing pushes because many players rely on Force Fields for defense.

Players often merge Archons when High Templar run out of energy in the field, or if the opponent has detectors that vitiate the Dark Templars' main strength.

The warp in cost of an Archon from two High Templars is 100/300, and the cost from two Dark Templars is 250/250. The cost of merging an Archon from one of each is consequently 175/275. Gas is a more "precious" resource within StarCraft II because it is used for teching and upgrades; therefore, it may be better to warp in Dark Templar to make Archons. However, the Protoss may use High Templar to save minerals for building chargelots, since chargelots are powerful when paired with archons. This may be especially useful to follow a DT Fast Expand, as the saved gas allows for a faster transition into a more "standard" method of play.

Vs. Protoss[edit]

Archons are strong against almost every Protoss unit, but most notably when up against Gateway units. Zealots are eaten up by splash and bonus damage while Stalkers will need up to 36 hits alone to kill an Archon. Sentries are worthless because Archons break force fields.

Their large size also spreads out your army, which reduces Colossus and Psionic Storm splash damage.

Saving Archons from near death and throwing them back into your army when their shields recharge can be a deciding factor in this match up, since small economical gains in a mirror match can make or break a game.

One-on-one, an ideal counter for Archons in PvP is the Immortal, which will soak up damage with Hardened Shield. However, Immortals generally stay near the back of the army to avoid Zealots, and players generally won't attack Immortals with Archons anyway. This makes Immortals a softer counter in more normal mixed engagements. Other approaches to dealing with Archons effectively include catching Archons with little support with a flank or zealot surround, or focus firing them with groups of Colossi and/or Stalkers.

Archons are "Massive", and can therefore destroy Force Fields. Note that the perimeter in which Archons destroy Force Fields is larger than what the model might indicate.

Vs. Terran[edit]

After being harassed with Dark Templar, a Terran player will place down Missile Turrets greatly limiting access to his base with cloaked units. To deal with this, leftover Dark Templar may be morphed into Archons and included in the main fighting force. As the current TvP playstyle favors Marine/Marauder use and both these units are subject to the Archon's bonus damage, the Archon can be a useful addition to the army. In addition, being a Massive unit makes them immune to being slowed by concussive shells. However care must be taken to avoid exposing Archons to direct fire from large groups.

It is important to note that the Ghost EMP Round will only drain 100 shields from the Archons affected.

Vs. Zerg[edit]

Their bonus against biological units makes Archons effective against all Zerg units. In fact, Archons can one-shot Zerglings and Banelings unless +1 carapace is researched. Conversely, this can be negated by the Protoss player researching additional tiers of Ground Weapons. Furthermore, an Archon with +2 weapons will also be able to 2-shot a Hydralisk with up to +1 carapace, and once +3 weapons is researched an Archon will always be able to 2-shot a Hydralisk.

One viable build is Archon/Zealot, due to the fact that using High Templar for the Archons leads to heavy gas usage and an excess of minerals. Zealots act as meat shields and create a wall between the opponent's forces and the player's Archons, allowing them to strike from behind the Zealot wall without being in direct harm. This combination is extremely effective against armies composed of non-armored units, against which the Archons' damage bonus is most potent.

In addition, they are very powerful against Mutalisks, dealing a quarter of their health per hit to everything in the splash area. Since Mutalisks tend to clump, this can be devastating. But this also makes them susceptible to Psionic Storm, which has much farther range, and most players prefer High Templars for this reason. Poorly controlled Corruptors will also be vulnerable for the same reason, with their armor bonus offering negligible resistance to the Archon's considerable damage.

Archons splash can also be used to kill Creep Tumors without detection. Two attacks on a friendly unit close enough to the tumor will kill it.
