That eye. It's amazing. I find it hard to decide if it's as good as Snorri's top tier equiptment of a single level below.
I can kinda answer that,
Because of a lack of set and BA synergy its a half step below Zharrgal which itself is a step below the top tier.
15 with BA Zharrgal + 20 Barak Azamar + 15 The Earth Shadow + 25 with BA Skarrenbakraz + 15 Set bonus +10 Eye of the Ancestors
Zharrgal and Skarrenbakraz both got a free +5 for BA synergy, otherwise the tiering was +10 for a Legendary and +20 for a Mythic item.
Depending on how you interpret this:
every round deal 1 damage to equipment regardless, roll DC 30,40,45 to add 1 damage depending on item quality.
It may have had twice the item breaking effect of Zharrgal which would maybe make it better.
Personally I think its the cumulative effect of both items however and shouldn't be treated seperately.
The most important thing about the Eye I think is that A) It was free, B) depending on how you interpreted soulcakes statements it may be a free +1 to our normal equipment limit which if true will significantly elevate it after we have a full loadout.
I think depending on your opinions and interpretations of partial data, you can make reasonable arguments about if its superior or not to Zhargall. However...
I think its safe to say thats its worse than both our Mythics by a significant margin, aside from their higher base increases, which are actually a bare minimum estimate as they give additional in The Earth Shadow trait and BA boosts.
Bungie has already shown how Regen doubles Snorris effective health pool against significantly more powerful enemies and that doesn't consider their effects in giving additional wounds. And Skarren was effectively another slowly growing bonus as it passively killed the Mearghs backup choir.
E: Wait the proc chance was from the eye:
Eye Round 1
DC 40: 34
No proc
I think that eliminates the argument that its better than Zharrgal given the current context of our other equipment (better stats, set bonus and not currently capped)
E:
It does make me a bit concerned that a Maergh this early on was this strong. At base she had an equal base combat modifier of 135. We had an extra +10 thanks to the grudge and the equipment destroying aspect of our gear really carried the fight.
But against anyone else that isn't Snorri she's would have been just as unstoppable against the throng as Snorri is against the Fimir army.
Thats basically their racial build, they punch way above their weight due to overcharged however fragile items from Daemon smithing.
Against a archetypical Runelord, the Meargh should have a higher bonus and it would be a test of the dwarfs ability to resist the sheer power of the sorcerer until they've weakened the magic and items enough that they can turn the tide.
This gal got unlucky to meet the Oldest Runelord in the North who can nearly match her in a contest of power (fewer wounds and regen) and brought multiple items to accelerate her items decay.
I don't think we really appreciated this before seeing this combat break down
