Lets not start pretending that the Macc. on elemental staves is currently quantifiable. The idea that they give a 10% and 15% increase respectively has always been speculatory. Now, I'm not saying that there is no Macc. increase, because its quite obvious that there is, but we don't know that its 15%
Go out and test for yourself. I've done a bit of testing myself and I'd have to say that it has to be
at least 15% based on how much difference it makes. It's much more visible with nukes in my experience, you will notice the difference in accuracy almost immediately. Also this is SE we're talking about, if the staves give +15% potency (which they do) then it's quite logical to assume that it's also +15% accuracy. Otherwise that'd make NQ staves what? 5%? and HQ 10%? Unless of course you're suggesting it's
more accuracy. Trust me, it's 15%.
I don't see much use to Alkalurops either, but A and B are complete horseshit.
There's plenty of stuff where you can enfeeble just fine with a wand + shield, but are most definitely not capped on potency.
And I ask the question, while this new staff looks awesome, does it replace our standard HQ staffs for our endgame/solo/trio use?
From what I gather he's mostly asking if this helps for things like Khim etc (endgame) and things like Zipacna or Fenrir (solo). The answer to this is mostly no. Even something such as Zipacna can be a pain to land on, I've tried landing in
full potency before and had about 50% accuracy. On things like merit pts you're going to be capping out anyways, especially if you're 5/5 on slow and paralyze II (from what I've seen so far taking slow II merits up past 3 has hardly done anything for potency, but it has made it easier to reach the cap, I'm assuming the same can be said for paralyze). On higher things like Khim you're going to need the accuracy from staves. Even if you continue to spam on Khim with this + your potency gear all you'll do is increase his resistance to your enfeebles, making it harder and harder.
With that said, how much use does it really have? Especially for what the OP has in mind? Mabye some, but not enough to warrant the inv-1. Stick to your club and shield if you will, but this staff doesn't have much use.
