During the Movement phase, instead of moving normally or declaring a charge, the Phoenix may declare an Emberstorm attack. Draw a straight line up to 18" in length. Each model in the way of this line (determined as for a bouncing cannonball) suffers a S 5 hit with Flaming Attacks.
After these hits are resolved, place the Phoenix at the line's end point. If this leaves the Phoenix in contact with an enemy unit, then place the Phoenix in combat with the unit, using the line along which it moved to determine which facing of the enemy unit the Phoenix is attacking. If the Phoenix ends an Emberstorm attack in combat with an enemy unit then it is treated as having charged that unit.
