It doesnt seem to do much damage. Does it only damages structures? And do I just use it as long range harass?
It's the piercing part that is good. It does moderate damage, it's not a bad ability. It damages everyone in a line. The key to the ability is using it to damage many, many units at once. It does good damage against vehicles. If you aren't going to hit at least 3 squads/vehicles than it's sort of not worth the channeling time.
Aim it at vehicles at long range, lines of infantry, or fleeing low health elites and such. The pierce makes it impossible to hide from so it's a great ability against the right targets.
it does significant damage to vehicles , heavy armor, like wraith guards or otehr elites.. but the ++heresy redacted++ has to be accurate.. it doesnt do a lot of damage to normal armor units.. so dont waste it on them.. it also does a good damage to buildings
Figured it out. Piercing shot is amazing for sniping whirlwind spam.
