Altairi

The Damage characteristic of Altairi is equal to the number of the current battle round.

In addition, once per battle in your shooting phase, you can declare that Ellathor will unleash a blazing sunbolt. If you do so, pick 1 point on the battlefield within 12" of this unit that is visible to it and draw an imaginary straight line 1mm wide between that point and the closest point on this unit’s base. Roll a dice for each unit that has any models passed across by this line. On a 2+, that unit suffers a number of mortal wounds equal to the number of the current battle round.
