yup including own unit~ it is friendly fire

2nd skill is negate 20 projectile shot,1 shot 10 energy

particle shot = mutas,mara,cannon,viking,stalker n etc that shoot projectile

weakness is raven got no attack, just 3 active skills.

used to have raven seeker missle spam tactics with 8-10 missle at clumps of my enemy before my main force stimming in and clear off the remaining forces....but rarely now as its only viable vs bronze level players.  Ravens IMHO, all their 3 active skills cost is quite expensive. 50 energy for turret, 100 for PDD and 125 for seeker missle. and they move quite slow as well. They are nvr going to be as good as infestor.. to fully utilized raven do you know u need to upgrade Corvid reactor, increase duration of PDD/turret and research seeker missle. not to mention u need to get upgrade at Engineering Bay for hi sect auto turret for +1 range for turret and +2 armor for building to make mass turret harrass more viable....
