Is it possible to range the fisherman who's gaurding the grail area or whatever, so I don't have to fight him?

You dont have to kill any fisherman. The only monster to kill in that quest is the 'black titan guard' Or whatever he is called. You may be able to range him from a safespot but the final hit has to be with excaliber.

You mean the guardian to the Fisher King kingdom. It's quite easy to range or mage him, he won't move at all. However, if you don't finsh him off wiht Excalibur, he'll never die.

ok thanks, I'll do that quest then.
