[Trexmaster]

River Sword used to be fine as it was, in the dark days of there being roughly two or three means of even dealing water damage that was fairly subpar compared to other forms of damage.

Nowadays with a wider variety of water damage sources, chaining together strings of attacks for massive damage (youkai spells being a huge outlier, river sword only exacerbating an already ridiculous damage source) is fairly common. Some people literally just use the sword for its 40% weakness.

I propose docking its 40% weakness to a 25% weakness on hit, that way it's far more unlikely to see 'Weak!' proc, while still providing a damage bonus.

Not to mention Splash exists now.
