The Nullifier is a mechanical hovering ground unit and has 100 energy points.
Karune says it has an attack similar to the Terran Marine's. The attack resembles a brightly-colored beam.
The Nullifier is produced from the Gateway and requires a Cybernetics Core. It costs 50 minerals and 100 Vespene gas.
Abilities
Force Field
Energy Cost: 30
Creates an invincible "globe" over a small area that lasts 15 seconds that blocks the movement of ground units and melee attacks. Units caught under the shield when it is placed may escape. The Colossus may step over the shield.
Null Void
Energy 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. Units that move out of the field immediately can immediately use their abilities.
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.
Anti-Gravity
Anti-Gravity can lift enemy units and structures (such as the Supply Depot) into the air, preventing them from moving and attacking, and rendering them as air targets. It does not work on resource-collecting structures such as the Nexus. The ability is channeled, which means that the Nullifier using the ability should not perform any other action (such as movement) while using the ability if it is to continue. It costs 50 energy.
Anti-Gravity can be used on allied units as well as on the enemy. It can even be used on rocks blocking the entry into an enemy base.
This ability used to belong to the High Templar.
Development
The Nullifier was previously known as the Stasis Orb. The Force Field ability was used by the High Templar in earlier builds of StarCraft II.
