Sentry/Development

The sentry was previously known as the stasis orb. The Force Field and Anti-Gravity abilities were used by the high templar in earlier builds of StarCraft II. Anti-Gravity was later moved to the Phoenix.

In earlier builds, Anti-Gravity could affect destructible doodads, but this was a bug.

Sentries dealt bonus damage against biological units.

Earlier builds featured an ability called Null Void.


 * Null Void
 * Ability Cost: 50
 * Prevents any unit caught in the target area from using abilities that cost energy. It does not affect abilities such as a stalker's Blink, a carrier's Build Interceptor, a Phoenix's Overload or an SCV's Repair. Immediately upon exiting a field a unit can use its powers like normal.
 * Nullify acts as a detector, decloaking units such as ghosts and dark templar and revealing burrowed units. The ability to detect cloaked and burrowed units is currently being subjected to balance testing.
 * The effect lasts 15 seconds.

As of February 2009 the nullifier lost the Molecular Disruption ability.
