You wanna know what I found funny in OB? Is that when I came out of the water from swimming in
Heavy armor I didn't appear to be wet, not one bit. Not only that. But I could also jump normally as if I were drier than warm wool blankets. I could still shoot Electricity from my very hands while underwater; But I would still take fire normally. Is there any word on being wet affecting gameplay? I shouldn't be able to shoot electricity out of my hands while wet without being hurt! And I shouldn't be able to jump like Bugs Bunny with water trapped under my glass suit of armor! And I should certainly look wet.
I think that if your wet, Frost and Shock damage should magnify while Fire damage is less effective. And your acrobatics should be less effective. This could add more immersion and "Amphibious tactics". Probably a great use for Water walking.
