Dunno, 100% of elemental ATK for a set that will benefit from Dagger Dance seems a little strong to me.

What Spo said. I've exaggerated a bit on the count, but it was on the idea to compensate for the small scaling.

If the scaling is gonna get buffed to match the other weapons of the same rarity, the bonus damage won't really need to be so big and 50% at most would be fair for each. But what is your opinion on everything listed in an overall, Dev? In specific, the Nihilist effect. Without it, they would still get absorbed by those monsters and 'lower' your damage, regardless.

Water can't be absorbed by player characters at all, Fire can, but only with Red Letter, and with a major drawback behind.

Added to that, this won't be able to be exploited by mages, since Hayabusa requires you to be using Hikage and Tsukikage, and they can't be used as casting tools for anything but Lightning (Thanks to Conduiz), BUT, Lightning can't be absorbed either.
