However, it does give you a better chance to keep the debuff active. Since it only has a 20% chance to go off, slotting more than one gives you extra chances to activate it and therefore means that it's more likely to be active a larger fraction of the time. Whether that's worth the slots, though, is up to you.

This is what it means to be a tank!
Just some quick additional, related info.
Because of the way it is implemented to keep if from self stacking from the same character, the AH proc actually won't stack from any number of sources. If you team with a buddy and both your character and his land this proc at the same time, they won't stack together. This is very unusual for this kind of effect. Presumably, as a Scrapper, you are a lone wolf and this is not a problem.
There is another -DR proc from the Fury of the Gladiator PvPIO set. That proc follows the same rules - it won't stack with itself from any source. However, the two procs will stack with each other.

Woah woah woah, that is very not how I am aware of it working. The debuff is flagged as "does not stack from same caster," not "does not stack."
I know for a fact that merc pets (of different tiers) can apply different instances of the same proc. |
Read the power information on the RedTomax page carefully.
Target: CasterLet's look up that granted power.
Grant "Set_Bonus.Set_Bonus.AchillesHeel" (10 seconds) (20% chance) If target is not caster [Ignores Enhancements & Buffs] [Non-resistable]
Target: CasterNow contrast what the proc does with a standard power that applies -DR. I'm going to pick Defender/Sonic Attack/Shriek. This is just the debuff portion.
RES(All Types) -0.20000 Melee_Ones% for 10.25s [Ignores Enhancements & Buffs]
Effect does not stack from same caster
Target: FoeNote that there is an additional level of indirection in the proc compared to Shriek. The Achilles Heel proc is granting its owner a power that grants another power to the target. The target becomes the caster of the DR debuff, which cannot stack from the same caster. Thus, no matter how many attackers grant the target that temp power, the target of the temp power can only apply the -DR affect to itself once.
RES(All Types) -20% for 5s [Ignores Enhancements & Buffs]

The way it was explained to me, Dechs, is that the player is not the caster of the proc, but the *target* is.

Down on the lower left, there are 3 fields;
Entities affected Caster
Entities autohit Caster
Target Caster
Someone correct me if I'm mistaken, but I'm pretty sure it's not stackable, and this is why.

If there's no stacking of the 20% DR Debuff, would this equation still be accurate for determining the affect of the Achilles' Heel on an attack chain?
Average DPS w/ AH Proc = Average DPS * (1 + .2 * .2 * (chances in 10.25sec))
That works out as base * 20% chance of firing * 20% debuff * number of chances in 10.25 seconds.
Be well, people of CoH.

They dont stack, but I have several in my Rad Blaster build to help increase my chances of the proc actually going off.
The hard things I can do--- The impossible just take a little bit longer.
If numbers are so much more important than a teammate who is fun to play with, forget about the game altogether and go play with a calculator instead. -Claws and Effect-
That works out as base * 20% chance of firing * 20% debuff * number of chances in 10.25 seconds.

Also, something to think about... I would be completely unsurprised to learn that there is a clock tick in between the granting of the temp power and the application of the debuff. That probably doesn't affect the next attack, since no one would be able to get their next attack in during one clock cycle, but it might have a small affect on chains by moving when the debuff ends.

While I'm not sure, my assumption is that multiple firings within the duration period are taken into account to calculate the probable percentage of effect uptime.
So the mythical claws chain of followup, focus, slash takes 3.96 seconds to run.
10.25/3.96 = 2.59
If my chain does 200DPS without the proc, then with the proc, at least by that equation, my effective DPS goes up to 220.72
If the chain took 10.25 seconds and thus only had 1 chance to fire off, then it would only be an average DPS of 208 DPS.
Be well, people of CoH.

My search fu is horrible or else id post a link.
Awhile back (maybe a year ago) someone posted a chart showing how multiple AH procs slotted would give the best chance to fire.
it was a great graph that really explained how AH should and should not be slotted.
If someone else with greater search fu could dig that up it would be awesome!

(100%-81%^(procs in 10.3 seconds))*20%
You can create a graph from there:
procs % buff incremental buff 1 3.80% 3.80% 2 6.88% 3.08% 3 9.37% 2.49% 4 11.39% 2.02% 5 13.03% 1.64% 6 14.35% 1.32% 7 15.42% 1.07% 8 16.29% 0.87% 9 17.00% 0.70% 10 17.57% 0.57%
And I say "% Buff" because that's the % buff to your DPS as a result of the debuff. To me, calling it a DPS buff is more meaningful even if it's less accurate. Same thing either way, though.

If I slot multiple powers with Achilles' Heel: Chance for Res Debuff will the debuffs stack with each other?
