Void drone is actually bette since I calculated the average damage of both and dustmaker only does an average of 1,5 more damage.
Void minimum + max damage. 143(min)+ 187(max) / 2 = 165dmg
Dustmaker min and max damage. 120(min) + 213(max) / 2 = 166,5dmg
But after void attacks once the enemy has -5 res for the entire match, so every hit after with weapons and void itself does 5 extra damage.
Let’s say you go into a match and it lasts 5 turns.
Dustmaker will do 166,5*5 = 832,5 average damage.
Then void does 165*5 = 825 average damage but lets say you attack 5 times. (once each turn) which is actually less than average since there’s usually turns where you’re able to spend both your action points attacking.
Then we add +10 damage for void (because you attack then drone attacks 5*2 = 10)
But void does -5 res after the end of EVERY turn so it’s going be even more additional damage.
825+10+20+30+40 = 925
If we go back to their average damage when we account for res drain it will look like this.
Dustmaker average damage: 832,5
Void average damage(5turn match): 925
Even when the match only lasts 5 turns and you only attack once every turn it still will be responsible for almost 100 more damage than dustmaker.
