Werewolves in Requiem are a bit bland. Just a flat buff, some drawbacks and little else. This mod adds some much needed flavor.

The health and stamina buffs are now variable, depending on how many hearts you have eaten. This lets you become stronger in human form as you grow your Werewolf powers. All amounts can be tweaked in the MCM menu. The buffs can range from 10 to 200, and by default, one heart will gives you one point of health/stamina (in lots of ten). These buffs can additionally be time locked, so they only show up after enough days have past, for players that can't resist just rushing to 200 hearts.

With the new buffs comes a hunger system. Every day you get hungry, requiring one more heart to satisfy the beast. This does nothing until you get to three days of hunger (changeable via MCM). After that, your debuffs will start to grow. The base debuffs are now 20% magic cost increase, as well as a cost of 40 lockpicking and pickpocketing expertise. Every day of hunger over the limit raises spell cost by 10% and the expertise loss by 20. These debuffs will not harm pure Warriors, but a Mage or Thief that takes the Werewolf buffs will be crippled without a steady supply of human hearts. The base debuffs now don't apply if you wear the Ring of Hircine although the hunger ones do.

You can now become a Werewolf more than once per day if you want.

In the future I might work on the Werewolf perk tree. Let me know if you have any suggestions.
