Energizer

"Equipped with onboard chrono boosters, energizer are designed to enhance the speed of purifier shock troops. Each energizer can also generate a power field, enabling access to the psionic matrix and warp network in hostile."

- Unit Information

The energizer is a variant of the sentry available in the single-player campaign of StarCraft II: Legacy of the Void.

Overview
The Daelaam gained access to the energizer after visiting the Glacius facility, and Karax added them to the Spear of Adun's forces.

Game Unit
The energizer's primary supportive ability is Chrono Beam, which increases the attack and movement speed of an allied unit by 50%. The low energy cost of Chrono Beam and its fairly quick casting time allows a comparatively small number of energizers to support a large army. Their second ability is Phasing Mode, where the Energizer generates a power field, identical to the warp prism, which is not available to the player in the campaign. This overall makes the energizer good for frontline aggression, able to buff allied units with Chrono Beam prior to confrontations and then acting as a power field to warp in reinforcements. The energizer is not able to move or attack while in Phasing Mode, but can still use Chrono Beam. If the player intends to make use of energizers, they should weigh their usage against havocs, the other sentry variant that also has powerful abilities to improve the combat effectiveness of the player's units. The major difference in the two is the energizer's Phasing Mode; if the player is reliant on warping in units, Phasing Mode is a critical advantage. The power field projected by the energizer also bestows the Matrix Overload status buffs, if the player has activated this ability on the Spear of Adun, further powering up the player's armies. The Warp Harmonization ability also allows the player to warp-in all units directly to the front line. If the player does not use warp-in or Matrix Overcharge, the energizer's usefulness versus the havoc is greatly lessened.
