@Eldar I think you can add option to use fishing rod at water elementals at yout Crystal Grounds scripts.
North Seacrest Grounds
Twenty Miles Beneath the Sea Quest
100 % quest need done ?
I think you can add option to take gold from floor yes/no, because at mine server i see many gp at floor, and char just taking gold, and going back refill after 20 minutes, and when he is attacking monsters, he is going take gold from floor first. I delete something in script, and now char is not collecting gold from floor. But you can add option for that.
