AV Resistance question

I was looking at paragonwiki's page on Archvillains, and it states the following:

"Archvillains are also noteworthy for having strong debuff resistance that scales by level. As of Issue 9, this resistance applies to -RunSpeed, -Recharge, -Endurance, -ToHit, -Defense, -Perception, -Regeneration, and -Recovery."

What interested me is that -damage and -resistance are not listed there(assuming there have been no changes since issue 9). I understand that -resistance is a function of resistance itself(and the wiki's resistance mechanics page is clear as to how this works), and I believe -damage is also handled by resistance, but I am unsure of how it specifically plays out. There is a sentence in the wiki explanation of resistance mechanics which at the heart of my question:

"It's also important to remember that stacked resistance debuffs always use the undebuffed resistance value when calculating resistance. This way there can be no cascading resistance failures."

What I would like to know is if that also applies to -damage(assuming I am right in that it is also resisted by resistance to each damage type).

So, for example, I am using EF on an even level AV(or any mob) which causes -30% resistance and -25% damage. the AV has 0% Smashing resist, 50% lethal resist and -50% Fire resist. They have 3 attacks which do 100 damage each, one Smashing, one Lethal, one Fire. While EF is on, how much damage would each of the attacks do? Clarification - I don't know if EF applies these debuffs "simultaneously", meaing -res would not affect -dmg, but for the purposes of the question you can assume that there is an existing -res power and then a -dmg power is applied, if necessary.

I hope the question is clear, the game terminology used doesn't help much:P Thanks in advance.

I think I heard somewhere that more -res actually increases the effect of -dam. Or maybe it was vice versa. Is anything like that true?

The answers given by Fleeting Whisper and Sliverado are contradictory. FW's states that -damage functions the same as -resistance in that it is always resisted by the base resistance value(even if that value is currently lower or higher due to buff/debuff) and Silverado's answer assumes the opposite.

Assuming FW is right, the answer to my hypothetical would be:

75 Smashing
87.5 Lethal
62.5 Fire

Obviously I would prefer Silverado's answer to be correct! If this is the case I will run, not walk, to the character select screen to roll a Rad/Sonic Defender.

Why do you think Rad/Sonics can solo GMs...

I wonder if a Kin/Sonic with much more -dmg available would work well. I think each Siphon Power and Fulcrum will stack with eachother, could be wrong though.

Or a good way to think of it is this: Resistance debuffs will always let you do that percentage more damage.

If your attack was doing 100 damage before the resistance debuff of 20%, with the resistance debuff you will do 120 damage. Because you will do 20% more damage. If your attack was doing 55 damage before the debuff, you do 66 damage after it.

In PvP this as I understand it -damage effects gets even weirder.

Let's say player A has a fire attack which does 100 damage, and 50% resistance to fire damage. You would think your -30% damage debuff will reduce his damage to 85. However your debuffing his damage BEFORE enhancements are applied. Someone correct me if my math is wrong here please. Let us assume this hypothetical player has slotted for +95% damage.

For his attack to do 100 damage he I think would have roughly 50 damage base. This is actually off by a few points according to my calculator, but I'll use it for illistration. First multiply 50 by 0.85 to determine the unenhanced damage after the debuff. This gives roughly 42.5 damage base. Then multiply the new base by 1.95 to determine the enhanced damage. My math says this is 82.875.


Again, I could have the math horribly wrong. Someone correct me if I do please. Keep in mind my math is going to be off by a few points to begin with. 50*1.95 isn't an even 100. It actually comes to 97.5 thus my example isn't 100% accurate to begin with. Again, if I did horribly mess up the calculations, someone correct me.
