It seems there has been a lot of incomplete and improper testing done on Miasma over the past few months, leading people to believe negative Power Duration does not increase damage. This is not true. Please do not edit the article unless you're absolutely sure.

Here is a basic test done on Phorid. No Power Strength mods were used. Only Power Duration was varied.

From top to bottom:

0% Power Duration: ~27px of damage

+136% Power Duration: ~27px of damage

-65% Power Duration: ~41px of damage

I think it's extremely clear that negative Power Duration increases damage. Now the question is why.

That was also extremely clear prior to all the edits of Miasma's page. PsycloneM and I have explained the mechanics before.

Miasma has 1500 base damage at rank 3. To calculate damage per tick, you divide it by the base duration of 4. 1500 / 4 = 375 damage per tick. The next part is the most important. Total damage is calculated by multiplying damage per tick by duration + 1. This is due to Miasma dealing an initial tick of damage when it starts. I assumed it was bug back in ~February when it was changed, but it seemingly hasn't been changed since. Anyway, that means at rank 3, Miasma deals 1875 total damage.

Now, with -136% Power Duration, the damage changes a little. Duration increases to 9.44. Damage per tick decrease to 159. Total damage is 1659. If you were to test this in-game, you would not see a damage pop-up for the reduced damage tick due to the 0.44 damage. That throws a lot of people off, but it should be clear in the enemy's health bar. Mine above do not show it clearly though.

Moving on to -65% Power Duration. Duration decreases to 1.4 seconds. Damage per tick increases to 1071. Total damage is 2570. This increase in damage is clear this time in Phorid's health bar.

Now there have been some claims that Miasma was stealth nerfed in one of the past patches. Further testing needs to be done, but it clearly still deals more damage with negative Power Duration.
