The only time you should put away your
Dark/Pluto's for non-resistant mobs is if you're using a damage ToM staff or a Diabolos's Pole.
Well, the damage boost on a magian dark-acc staff will be equivalent to what would be on the Dark Staff, wouldn't it? So technically, your statement should only apply to the Pluto's Staff. Or am I overlooking something else?
I mean, everyone SHOULD already have a Pluto's Staff at least anyway, but yeah
Ah yes, you are correct. Unless you get into a situation where you're using a darkness affinity atma, because that would dilute the damage increase of the ToM staff slightly, but not the dark staff. But that's probably a footnote that nobody would even care about.
The only time you should put away your Dark/Pluto's for non-resistant mobs is if you're using a damage ToM staff or a Diabolos's Pole.
I thought I remembered tests showing that Diabolo's Pole was not as effective as Pluto's for Drain/Aspir. Did I miss something somewhere?
I'm pretty sure I posted a few times over the years explaining that Diabolos's Pole has higher potency than Pluto's. It wasn't completely clear at first because the distribution of aspir/drain damage wasn't completely understood, and the only significant evidence was a higher maximum drain/aspir. But now that we know the distribution is uniform between the max and max/2 (before resists), we know that increasing the max damage means increasing your average as well.
I never did see any evidence to support the theory that Diabolos's pole has no accuracy bonus, and it would require fairly rigorous testing to make that determination. Maybe it has been confirmed at some point though; I haven't looked for new testing on it in a long time.
