A Sentry can make only 1 hallucination of: Archon, ColossusImmortal, Phoenix, Void Ray, Warp Prism; 2 hallucinations of: High Templar, Zealot and Stalker; and 4 Probe hallucinations.

Force Field

Force Field – A Plasma barrier that barricades the path for ground units and they can't pass through. However massive units will destroy this barrier upon contact. Last for 15 seconds.

StarCraft 2 WCGCompetitive play with Sentry

 

VS Terran

The Sentries are crucial for every PvT match, because of their Force Field and Guardian Shield abilities.

  • Force Field. You can use this ability to block the entrance to your base and thus stop an early marine rush. Another tactic is to use the spell to split your enemy’s army so you can deal with it more easily or you can even block the entire army, if you can handle it. The Force Field prevents the opponent from reaching your vital damage-dealing units like Colossi or Immortals.
  • Guardian Shield. This ability reduces the incoming ranged attack by 2, which makes it extremely effective against the enemy’s Marines.

VS Protoss

In mirror matches the Sentry is useful to block the entrance to your base and to reduce the damage of the enemy’s Stalkers.

VS Zerg

In this kind of matches the Sentry is important to, yes you guested it - to block the entrance and prevent early rushes. What’s more, the Zergs rely greatly on their ground forces, so a well-placed Force Field in mid-game will reduce their efficiency. Keep in mind that the Roaches have only 4 range and your Stalkers - 6, so a good Force Field will render the Roaches useless. The Zerg players often use Mutalisks, but your Guardian Shield does a great job negating their attacks.

 

Countermeasures

 

VS Terran

  • The Siege Tanks in siege mode are very good, thanks to their great range.
  • The Ghost’s ability to burn energy, EMP, is perfect for these little robots.
  • Do Not Use Reapers, because they can't jump over the Force Field.

VS Protoss

  • Use Stalkers with researched Blink ability and focus-fire the Sentry.
  • The Zealots with Charge ability are efficient too, but watch out for the Force Shield.

VS Zerg

  • Roaches, with the upgrade that allows them to move while burrowed, are perfect for killing Sentries.
  • Send many Zerglings with the Metabolic Boost ability to destroy the Sentries as soon as possible and then attack with the rest of your army.
  • Use the Ultralisks’ massive bodies to destroy the Force Fields, so that your army can pass and crush the rest.
