Tried it out but not having any luck here. E.g a spitter has an acid attack with a splash damage effect as:
Duration 9 seconds
Damage 1.76k/s + 17k/s Acid (a quality biter mod)
2.94 + 2.82k AOE
Mod settings: Hitpoints per second of turret shields: 5000000
1 single acid attack immediately destroys the turret with these settings. I keep raising it and observe no change in the survivability of the turret. So I'm certainly missing something here.
What do the different colored bars mean by the way?
