Diadem

Artillery Targeting

This structure launches an artillery beacon at its target, and fires its primary attack at the beacon's position.

Ion Field

Diadem attacks leave behind a field that deals 100 damage over 10 seconds to all ground targets. Units that move through the field gain 150% attack speed for 2 seconds.

Liftoff

Lifts the structure, disabling its standard functions, but allowing it to move and land elsewhere.
