I just completed the Silver Hand Questline with the Companions in Whiterun. Turned into a werewolf for the first time, ate some people etc. How does the bloodlust system work? Do I need to feed on people often? Is there any way for me to "lapse" into being fully human again? Does something limit beast form so I don't just use it all the time?

There didn't seem to be any explanation as to how the system works, they kinda just threw me into beast form and called it a night.

Sincerely,

-A noob werewolf.

They really need to add a timer on the warewolf transformation so you can tell how much time you have before you turn back. But yeah, you change back to human after X amount of time. Feeding on people increases the amount of time you're a warewolf. You can only turn into a warewolf once per day. There's a cure for being a warewolf if you ever want to turn back, though I don't think you can become a warewolf again after that.

the beast form runs on a timer and the more you feed the longer you can stay in the beast form. if you don't continue to feed then you turn back into a human.

I think the timer is 180 seconds, which you can prolong by aforomentioned techniques

You can activate beast mode at any time once a day. As bloodlust, its what keeps you as a werewolf. The more you feed, the longer you stay a werewolf.

Also, post this in the spoilers section next time spoilers are involved. Some people probably don't want to know about this, even though the majority of us probably already know.

Sorry, thought adding "possible spoilers" to the topic was enough.
