Hint: Never attack humans:
You first meet a human in Malchia's domain. Armed with a crossbow, he will shoot at you. Just run right past him and do nothing to him. Kill the vampires. Sometimes if you stay where the hunter is the vampire will come at you and you and this hunter will kill it. This shows him your no threat. But if not just continue on after killing the vampire. Then when your in the factory in Melchiahs home you'll meet a second hunter. He should fall to his knees with his arms raised. No human will harm you now so long as you harm no human except the vampire worshippers. This makes running through the Citadel a snap. Just remember there are no vampires in it.

Hint: Spell use on Humans:
Kill humans with Gylphs. They will not seem to notice you did it. You can use several of them for all sorts of wierd effects.

Do anyone notice that soul Reaver is only avaible at spiritual world, well, only get the material reaver and you will have a Reaver for Material world.
