If you want a water melee i think you need 3 Int 55 Wis then you put more on Str then you would put on Con like you normally would for a water, then It depends on if you want it to be quest or pk build. Quest build would be Con Str 3 int 55 wis and A good amount on agi so you can also seal. If your gunna do a pk char then 55 wis 3 int and you would want your char to be fast and strong, so most pk chars have the main focus on Str and Agi, then what ever they can spare they put on con.
