So, I missed that back in December, someone asked me to work up a version of the Vampire and Werewolf for Savage Scrolls (I am REALLY bad about checking comments, I am sorry). As I am actively avoiding other projects and pretending not to, let's play with it!
Note that I have never done the vampire run. I'll do werewolf (one of my favorite things is "rage across skyrim", where you turn into a werewolf and run from bandit hold to bandit hold, killing everyone), but I am incapable of playing a bad guy, so I never do vampire. I'll be borrowing this from UESP, rather than personal experience. Which is why I'm starting with werewolf. This can, of course, be used as a template for any sort of werewolf in Savage Worlds or the Fantasy Companion.
Mystic Powers: Werewolf
Tamriel has many types of lycanthropes, and each with different features and means of transmission. Skyrim is home to werewolves, and Solstheim has werebears, while Daggerfall have a varieties of werewolf and wereboar that are passed through semi-magical diseases. The werewolves of Skyrim (discussed here) largely do not spread their condition via a bite, and also have a larger degree of control than the ravening monsters of Iliac Bay.
To become this type of werewolf, one must either be born into a werewolf clan (as seen in Frostmoon Crag on Solstheim), or inducted via ceremony (such as seen among secret groups who would not appreciate my revealing of their ways). Werewolves are universally hated by non-werewolves in Skyrim, as their beast forms are compelled to devour the hearts of their foes. However, it is little known that most werewolves have full control over the transformation; it is a rare circumstance that can compel them to assume the beast form against their will.
A character with this edge acquires 10 Power points, separate from other power points they may have. At will, they may use the Shapechange power to assume the form of a werewolf; seven feet tall, with long arms, digitigrade legs, and vicious teeth. This transformation requires all 10 power points, and requires an exclusive action; you can do nothing else the round you change shape. The shapechange will subsume worn weapons and equipment; these become unavailable, but are not destroyed or left behind. It will last for ten minutes, unless the werewolf feeds.
While a werewolf, the character gains a claw attack for Str+d6 damage. They receive a one die bonus to Strength, Vigor, Fighting, and Intimidate, +2 to Armor and +1 to Size; between the Size and Vigor boosts, their effective Toughness is raised by 2, as well. Their pace increases by 2, and their running die increases by one size.
On the downside, the transformation reduces Persuasion by two die types, and applies a -2 penalty to all Persuasion checks. Manual dexterity is limited, so they are unable to use weapons, or anything more complicated than a door handle. The character cannot use spells, and potions must be used on them. Furthermore, they gain an Environmental Weakness to Silver; weapons made of silver do double damage in their beast forms. Being known as a werewolf will impose the Outsider (Major) flaw upon the character.
Feasting
The werewolf transformation lasts for ten minutes, unless the werewolf feasts. To feast, they must eat upon the heart of a Human, Mer (including Orsimer), Khajjit, or Argonian. The heart does not need to be beating, but it must be warm; in Skyrim, this is usually no more than an hour, or even less in the depths of winter. Such feasting takes two rounds, and while eating, the werewolf is Vulnerable. Each heart so devoured extends the transformation for ten minutes. When finished feasting, the werewolf immediately makes a Natural Healing roll.
Werewolf Power Points return slowly; only one point per two hours. Feasting restores one of these power points with each heart consumed. Werewolves cannot exceed their maximum (10, plus others granted by advanced powers Edges).
Advanced Powers:
Once a werewolf has adjusted to their new form (gained another advance), they may choose Werewolf Edges to bolster their power while in their wolf form. Some Edges provide supernatural powers; others improve the beast form itself.
Howl of Terror:
The werewolf gains 5 werewolf Power Points. While in beast form, they may use Intimidate to activate the Fear power in a Large Blast Template surrounding them. This use requires 5 power points.
Howl of the Pack:
The werewolf gains 5 Werewolf power points. While in beast form, they may summon wolves. The first wolf is 2 power points, and each additional wolf is 1 additional power point. For 6 power points, they may instead summon a single werewolf; additional werewolves are 3 power points each. Mixed groups may be summoned, requiring 6 power points for the werewolf, and 1 per wolf or 3 per additional werewolves. (Summoned werewolves should use the Werewolf stat block in SWADE, p. 191, but remove Fast Healing, Fear, and Infection). As with the Summon Ally/Animal/Monster powers, the duration of the summons is 5, and may be maintained for 1 power point.
Bestial Strength (requires Seasoned)
While in beast form, your claws do Str + 1d8 damage, and you gain a +1 to Toughness.
Improved Bestial Strength (requires Veteran)
While in beast form, your strength increases by one additional die, and you gain an additional die in Fighting.
Bestial Feeding (requires Seasoned)
Your targets no longer must be men or Mer; you may feed upon animals, monsters; any corporeal creature with a heart. However, when feeding from these creatures, the transformation only lasts for 5 additional minutes, and the werewolf must choose between regaining a power point or making a Natural Healing roll.
Curing Lycanthropy
It is possible, though various means, to be cured of lycanthropy. Rumors tell of potions, passing the curse to those whose generational lycanthropy is latent, or killing those who originated your curse; each curse will have its own means. Being cured of lycanthropy, however, does not undo that which has been done; you can no longer use your lycanthropic Edges, but they are not replaced with new Edges.
