Double Conc. Opp Weapons

[TheKaige]

I've heard it said from both sides, but ideally what I'd like to see is a video with some number crunching, if possible, that can verify that double Conc. Opp weapons stack; basically I'm asking if anyone can verify whether or not it stacks, or for a link to a post that can confirm it. I've looked for a while, but haven't found any conclusive posts.

If it's important, I'm considering making two Conc. Opp scimitars/maybe longswords (Elf v. Human) for a 20 cleric.

Quick clarification: I am aware that Conc. Opp weapon + Accessory stack; simply curious about Weapon+Weapon+Accessory. My bad for not saying that at the beginning.

There are some existing threads on this. It was fairly rigorously tested.

The conclusions based on the data:

2 items don't stack.

1 weapons and 1 item does stack--but there is a risk that this will go away in the future.

I don't recall a formal test on 2 weapons.

The last rumor mill went through this, and determined that concordant opposition does stack when one is a weapon and one is an item.

This is correct, but may be changed at any time as it is not WAI per Eladrin.

I'm not sure on two weapons, but a weapon and an accessory will stack, and two accessories won't.

I would doubt two weapons would. But I would never craft two conc-op weapons or Weapon+accessories, even if they did stack, because there's a high chance that would get fixed.

I really wish I could find the thread I think vhlad started where he posted his test cases and data.
All i can find that's left of it is a partial quote in the 31page multiple concopp thread, which is otherwise filled with so much conflicting information and "proof" as to be useless.

I still see people who were around at that time divided into camps on what worked or not, and they mostly don't agree even now, although the most parroted response is weapon+accessory stack.

Of course I can find cases to both prove and disprove that on the forum.

That's why I wish I could find the noted post.
No torc, cleric hireling healing. Three cases tested.
That one demonstrated a repeated deflection in sp regained/fixed timeframe ranging from250-600 for weapon+weapon only compared to weapon+accessory or two accessories.

Then there's the whole terminology problem.
There's stacking as in multiple sp or hp procs simultaneously.
Then there's stacking as in increased chances of either effect going off at all.

Doubt anyone here could tell you definitively which one of the two cases was in effect or not, I know I can't for a certainty(yet).
