I always ignored these Zora weapons due to their low base damage, but I decided to test their double damage buff when Link is wet. At first, I was impressed because I never destroyed a Flux Construct II in such a fast single burst. But after a few more post fight tests, I realized that that damage was without the double damage from the wet effect, as the effect applied by that fruit only lasts around 7-8 seconds, and it took me 14 seconds to land the first hit on the boss.
I still think these Zora weapons are pretty niche. You either have to be fighting in the rain or taking advantage of Sidon's sage power (I haven't unlocked it yet), which like all powers can be really clunky to activate in combat at times.

Also bump.
