Xi Cannon
The Xi Construct's front opens up, firing a devastating beam at its target that deals rapid damage. There is seemingly no range limit to this attack.

The Xi Construct cannot change its firing angle when using this skill, but it can move back and forth horizontally to chase its target.

This attack has a cooldown of 8 seconds.

Tetra Alpha
The Xi Construct spawns with 4 allied on its corners, which support it with additional firepower. After these are destroyed, the Xi Construct periodically re-summons them.

This attack has a cooldown of 4 seconds. Up to four charges can be stored, and it can only be used if the currently existing Alpha Constructs have been killed.

Xi Barrier
At low health, the Xi Construct creates a golden spherical shield around itself, reducing the damage it takes.

This attack has a cooldown of 15 seconds (which does not begin until the shield has disappeared).
