300 x 85% = 255, subtract that from 300 (300-255=45)

When you divide 300 by .85 you're finding the number that 300 is 85% of... Or 352.94 x .85 = 300. This is NOT the correct way to find percentage buffs

As well the percentages are multiplicative, meaning with HT your 100 potency skill is hitting for 115. After disembowel (10% buff) the new potency is 126.5 (115 x 10%) instead of 125. This also applies to B4B. Best to go back and read the first page Avyar breaks it all down. I'm doing a terrible explanation.
I think you did fine explaining.

it's just original potency X Total DMG+ Buffs X DMG+ from resistance reduction. That's general rule for weapon skills and auto attacks.


Then we open a can of worms by discussing whether DoT damage is reduced by piercing resistance (Disembowl) or magic resistance (Foe Requiem)...

DoT tick damage btw is determined at the time of application, so if you apply the DoT with your buffs up, the tick damage remains at the higher value for the subsequent ticks until the DoT wears off.
