Thanks. How do I know what stage I am? I'm already a vamp but that guide says there's 4 stages. Also, I've been exploring for nearly 50 hours and have yet to see werewolves in the wild. I fought one through a side quest earlier though.
You can tell what stage you are by your frost resistance and powers....
More easily the frost resistance.... You are good to go as long as you are below 100%.... if you are at that... which is stage 4's resistance rating.... then dont go anywhere NEAR a town.... and that dang shadows spell doesnt work for crap in or around a town since the higher level guards will just "lul wut?" you while you think you are invis.
Also, before doing the quest... I recommend feeding down to at least 50% frost res.... because I was at 75% (stage 3) and when I waited for dawn for him to perform the ritual I went to stage 4 and he attacked me... causing me to load a save and feed.
edit: best places to feed at level 4 are the random farms and mills you run across on the country side without guards patrolling them.
