I'm facing a similar dilemma. I got one last night that's Int, Vit, and AD. It's already got essence as the secondary. My initial inclination is for Vit, which would drop me from about 1M HP to about 900k.
AD is a good stat overall, but my concern is that I don't know that it's particularly helpful for this build - which is my own variant on Inarius bone storm that uses Siphon Blood + Iron Rose instead of Grim Scythe. AD doesn't benefit Mirinae, and I'm not entirely sure whether or not it works with the bone storm. I'm not sure whether or not it works with Pain Enhancer either. Given that Blood Nova is coming from Iron Rose, and not its own cast, I'm not even sure if it benefits from it. Based on some testing, I know that it still receives the benefit of things like Scythe of the Cycle, so maybe they're treated normally for AD as well, I'm just not sure.
Another thing I want to keep in mind is how useful it might be for other potential builds that would also use Corroded Fang, like a Trag set build perhaps; that way it'd still be useful in either scenario.
I'm probably overthinking things. It's just a nice weapon that I don't want to mess up. 100k HP isn't that big of a deal. Hell I could roll the AD off my shoulders for % life instead and be close to a million HP again anyway...
I'd appreciate anybody's thoughts/insight on the matter!
the roll was just good. I would've kept it that way. It's not like that the 10% dmg (even less if using a dmg offhand - don't know how they're called for the necro ^^) instead of 1k vit would make your necro much stronger.
I remember so many suggested item re-rolls that afterwards were regreted. Especially on a weapon. Why rushing the re-roll if you're not 100% certain? It was just very good the way it dropped.
