Twin Valks 25-Hardmode shield

[repent]

I'm getting mixed information about the effect of dark shields and light shields on dps. In several forums, they discuss changing color to dps the off color shield. In other forums, some people indicate that the color of the shield is irrelevant. That is, a shadowpriest with black dpsing the light guys light shield does the same amount of damage as a shadowpriest with light dpsing the light guys shield. To make it clearer, some people say that although the twin valks themselves take increased damage, the shields are effectively colorblind. Anyone know who is correct?

As far as I know, this is incorrect. The shields aren't actually entities, you are still dps'ing the bosses, with all relevant effects applying. They just happen to be absorbing 1.2M damage.

FYI, my understanding to my own question is that you do more damage as dark attuned to the light shield. However, others suggested that you can do things like be light attuned and use an aoe affect (bladeflurry sp?) for one, as light attuned against the dark target, and then when the aoe portion hits the light shield it does the normal damage. (ie the shield is colorblind to the aoe effect) Others suggested the shield is colorblind outright, I just was hoping for clarification either way.

Experiences last night tell me that the shields are not entirely colorblind. We had no issues killing opposite color shields, but we missed every same color shield. This was, of course, in 10-man heroic. So, yeah, you should definitely change colors for shields.

(Thank goodness we still one-shot the fight )

As far as I know, there are only two abilities in the game - blade flurry and sweeping strikes - that work for full damage on the off color shield. They operate on some principle that the secondary target always takes the full damage of what the primary target took.

Because of this, you can plant your arms warriors and rogues on one of the twins, and if close enough, they can cleave to the other. So treat them as entities that attack both twins at once - if you've got 3 rogues/arms warriors, and 17 dps total, you want 7 on one, 7 on the other, and then spread those 3 however you'd like. Effectively, if no one changes colors, you'd have 10 "good" attuned players attacking every shield, and 7 bad ones.

The shields are not colour-blind. However, it's not necessary to switch colours, either, just switch targets and take it out. This probably only works if you have dps split on the twins, though. Single-colour strategies would require switching, I assume.

I am not entirely positive, but I am pretty sure that last night in 25-man norm my Seal of Command (yes, I was experimenting) procs were hitting both equally.

The "essence" works that you deal double damage to the target of opposite colour. My Hotr deals X*2 damage to my twin and X to the other one.

It's not necessary to switch colour, BUT if you don't switch you'll hardly make it in time.
