Mothership core

The mothership core is a protoss unit built from the nexus. It provides support abilities. Only one core can be built per player.

Previously immobile, the mothership core became a mobile unit during the beta test. It can attack while on the move.

Game Unit
The mothership core is available to players very early in the game and it is highly recommended that they build one in this stage.

The mothership core was created to solve the problem of multiplayer protoss vs. protoss games, said games rarely going to mid-late game due to the warp-in abilities negating the defender's advantage. Its purify ability is a counter to this, along with countering zerg rush techniques. It is also intended that its recall abilities will allow protoss players to be more aggressive.

The mothership core's repulsor cannon is only available in its mobile state. To use purify, it must attach itself to a nexus.

A tactic for the core is to use its teleport ability to warp to nexi at expansions, then set its purify ability. This makes such expansions easier to defend.

Its unit portrait is the same as that of the standard mothership.

Development
Prior to the beta test, the mothership core was immobile, remaining atop the nexus.
