Twin Dance does not work with acidic claws when you consider that two weapons mean taking up your off-hand slot.

I just wanted to point out this very fast, this is not exactly true but I would like to add to the thread anyways in support, to summarize as best as I can:

With Mixed Martial Arts you can twin dance fists/bare fists with acidic claws, this is more notably effective with a few on-hit fists or even grudge claws, but I also want to bring up that it would not be overly strong aside from fists.

I can see no reason I'd use Grudge Claws with this setup over say Seiryuu Tessen (Grudge Claws comes with its own drawbacks), so I see no reason why Acidic Claws cannot receive a buff that ties to acid attack, especially when that would mean the item would require some form of investment, which is much harder for STR builds to feasibly achieve.

EDIT: I never even realized this WASN'T the balance fu forum, woops
