What will you run?
I think first place for me is the class legendary Expanded Potential. A close second is a general legendary: Norgannon’s Sagacity. Both of those are perfect fits for the spec. My third place Legendary might finally be from the Arcane spec, and it’s a tossup between Arcane Bombardment (AOE) and Arcane Harmony (ST.) I might even consider Echo of Eonar, another general legendary, as the third; just to have the crafted ring.
I believe Arcane Harmony is the strongest legendary for arcane, followed by EP.
Why would you pick both of those? That’s like saying, “This straight is nice, so is this 3 of a kind.”
I would never pair Arcane Harmony and Expanded Potential. Arcane Harmony deserves it’s own AM/SP CDR build, which is one where Arcane Charges are hard to find. The proper legendary to pair with that would be Siphon Storm, imo.
Norgannon’s Sagacity is a beauty for those of us willing to cast still. It’s like a passive, on demand Ice Floes. Couple it with Slipstream, and you’re never bound.
I believe you will only be able to equip one legendary at a time. So for now can’t pair any of them up.
I wasn’t talking about pairing, but are you seriously asking why you would pair a legendary that increases the damage of arcane missiles with a legendary that gives you more arcane missiles?
I think you are right for top two, but yeah I do think they’re top two in different builds, assuming we get multiple legendary options down the line.
Pairing Arcane Harmony to increase your Clearcasting proc by 10% damage, if you’ve picked EP to cast Arcane Blast, instead of spamming Arcane Missiles… I think that damage gain is inferior to the movement Norgannon’s provides for your AB casts.
Likewise, if you’re spamming Arcane Missiles because you have the Arcane Prodigy conduit, doing the whole Shifting Power CDR build, you’re not casting Arcane Blast and EP is literally worthless. Siphon Storm would step up as the secondary legendary choice.
