What did he say that was so offensive? And I am sure when he says Zamorak sword everyone knows what he is talking about. I think we can all be a little more curteous to new members so that we dont scare them away. To answer the original question, waterfiends are weak to crush attacks so the Zamorak Godsword should work but you may wish to use something faster like Saradomin Godsword or Zamorak Spear. i hope you mean saradomin sword because saradomin gs is same speed
