No one has ever exactly measured the speed and strength of the hammremir, so only first person observation is available. This allows for some guessing. In addition, there is a difference between the physical capabilities and restrictions of the human shape and that of the wolf body.

The Human:
A male hammramr of average build can run roughly at the top speed of a domestic horse (so about 70 km per hour or about 44 miles per hour). So seeing them running would still make it possible to recognize a human shape, albeit only if you actually pay attention. Otherwise, their reflexes are so fast that only the most observant people with short reaction times and fast reflexes can see the hammremir's actual movements. For the everyday person, it would barely be more than a blur.

Their strength can also only roughly be measured. An average male hammramr can easily jump about 10-15 feet from standing position, snap necks easily with one hand, and carry an adult human with one arm. It is estimated that their strength is about the same as that of a North American Grizzly, so throwing a human through the air for several feet with one strike would be easily possible.

Their dexterity is not better than that of any human but can be honed through practice. In addition, their increased strength makes body-building harder for them. Due to their increased strength and speed, they, of course, would have to run longer and faster, as well as manage bigger weights (or train longer/faster for muscle definition) to have the same results.

In addition, the hammremir's average body temperature is about 2 degrees higher (meaning 39 centigrade/71 degrees Fahrenheit). So freezing to death is more difficult, but overheating is also more likely, as evidenced by the fact that they sweat more easily than humans in warmer climates.
There is however one feature to their bodies that is usually considered completely beneficial: their regenerative powers. While it is not possible to regenerate lost limbs or organs, hammremir can regenerate skin cells relatively quickly. This allows the werewolves surface injuries (cuts, bruises, and scars) to heal within seconds or minutes, depending on the severity of the injury. This quality even acts as a sort of buffer against the effects of aging.

To some extent that is, the hammramr still ages the way a normal human does. However, the regeneration allows for the fact that they don't feel it so fast, since tissue and bones of course regenerate faster after injury than those of a human of similar age, and, therefore, wear down slower. This effect is also the reason why a hammramr could work out more often than a human since any injuries from such a workout would heal faster. Apart from that the regeneration basically works the same as those of humans do, just much faster, so a hammramr can be burned or shot via several bullets, the only factor is the amount of damage done fast enough. A hammramr can still scar from normal wounds; they usually just don't because the wound is closed so fast.

They can still be simply killed by a single shot if vital parts of the brain are damaged (in other cases they might survive brain damage that would kill a human if the brainstem or upper spinal cord are not completely destroyed) and it is not possible to regrow more than a fraction of the brain. Losing the brainstem or more than one-tenth of the rest of the brain is not a recoverable state. As a final note, if a piece of the brain is lost and regrown, the werewolf may be forced to relearn certain things — possibly including skills, the ability to speak at all, etc. - and may or may not lose memories, depending on what section of the brain was lost.

With all their physical benefits, there comes a price: metabolism. Of course, as with humans, metabolic rates can differ from person to person but usually stay stable until you reach a certain age. On average, hammremir need to eat more and more frequently than humans do, amounting to about four meals a day or a normal complement of food supplemented by some substantial snacks. Just like humans they are still omnivores albeit they might lean more towards diets heavy with protein and fat, but of course, in theory, they could be vegetarians as well.

When the warrior is injured, his regeneration rate begins to move more quickly and the needed energy ends up being drawn from the warrior's inner reserves, and therefore needs to be replaced. Minor damage (cuts, scratches, bruises) doesn't measurably increase a warrior's appetite, unless it happens often enough, or the hammramr is already starved. In addition, substantial blood loss can also significantly slow down healing. Healing serious damage (stab wounds, gun shots, severe burning) over the course of 15 minutes or more is enough to make the werewolf's stomach growl loudly. His metabolism then kicks up a notch to provide the required energy.

A convalescent werewolf needs to consume half as much food as he usually does, since simple energy is not enough to repair the body. Due to this, a werewolf might literally devour huge amounts of meat, eggs or sugar (either pure or mixed with water) to regain the energy he had lost during healing. There is a, thankfully very rare but also very pervasive, myth among the human warriors. According to this superstition, a werewolf will never feel sated after recovering from severe injuries, unless he has consumed the appropriate part of an enemy's body. This myth has no basis in an actual need but has its roots with some depraved individuals, and is most often believed by werewolves with the appropriate psychological disorders.

One aspect of wolf lore that is not a myth, is their susceptibility to wolfsbane, which burns their flesh, and, when ingested in diluted, form weakens them dramatically. No one knows why these plants, affect them this way. The olfactory and acoustic capabilities of the hammremir are far above the level of a human, but whether they are on the same level as those of their canine counterparts is not known. Again, it has never been measured but a warrior is known to be able to smell arousal, track scents, hear the heartbeat of person standing next to him under normal conditions, and hear a normal conversation about a hundred feet away.

Actually, werewolves' ability to tell when people are lying is not some sort of mystical lie detector, but, rather a skill acquired through experience and usage of their advanced ability to hear the human heartbeat. This also allows werewolves to be able to tell whether a person is frightened or aroused, etc. However, this skill is not foolproof. And a good liar, who is capable of controlling his body-reactions, can make a hammramr think that he is telling the truth, because there is no increase in heart-rate, or any other bodily reactions typically associated with lying. Also, in theory, werewolves' exceptional hearing abilities could allow them to hear and recognize background sounds that human's wouldn't even notice. Of course, acoustic overload is more likely for them as well.

Additionally, the werewolf's enhanced olfactory abilities are the reason for their heightened sense of taste. The sense of smell of the hammremir also allows them to identify each other, since werewolf blood carries a smell specific to their kind. Those who are unaware of the species, would typically describe that scent as almost animal-like. In fact, it is a scent that could best be described as a mix of sweat and pine needles, with a hint of human blood.

The Wolf:
The abilities and requirements of the human form of the hammremir are already barely known, the wolf-form is a territory where barely even the first steps have been made. What can be said for sure is that the wolf-form is much faster than the human one, due to the wolf-body being better suited for fast running than the human shape. In addition, many claim that their wolves are much stronger than themselves, since they are known to break the chains their human forms were unable to break. However, whether this physical advantage is due to their muscles being proportionally stronger or, simply due to the differences between the canine and the primate shape respectively, the mental drive of the wolf to break free is not known, since the werewolves themselves have at best hazy recollections of these events. Not surprisingly, there have only been a handful of people over the centuries bold or stupid enough to spend a night of the full moon with a werewolf.

Perhaps the wolf-form has better olfactory and acoustic senses, due to its canine physiology. However, there is currently no evidence for this. That the wolf-form is better equipped to deal with harsh climates due to its fur is practically taken for granted, albeit, of course, never tested.
In theory, it could have different dietary requirements than the human form. Despite the fact that humans and wolves have similarities in their diets, there are also differences. But usually when in wolf form, the hammremir simply maul everything in sight, without actually eating anything. However, some mentally afflicted werewolves, as sad as this fact is, provide the greater community with evidence for different dietary needs by eating huge masses of food the wolf form obviously could not sufficiently deal with and had to get rid off by vomiting.

One theory is that the wolf-form might be very susceptible to sodium fluoroacetate. While a high enough dosage could kill any species, it takes only a very miniscule amount to kill a canine. Therefore, it is assumed that a werewolf could be easily killed with this while in wolf-form. Whether the wolf-form actually is more susceptible, or the human-form is more resistant against the poison than a base-line human is not known to have ever been tested, since no one is known who had ever dared. Some more paranoid werewolves take this as proof that it is deadly, since they attribute this lack of information to the lack of poisoned survivors.

The Transformation:
Usually the werewolf transformation starts around the time the full moon is fully visible over the horizon. Of course, or sadly, the belief that you don't transform when you don't see the moon is a myth as well as the rumor that you die when you see a lunar eclipse. While it is understandable why a werewolf might hope these myths to be the truth, the hard reality usually teaches them better.

Without a doubt, the transformation of the hammremir is by far the only aspect of their condition that nearly everyone of their kind could live without. Sure some revel in the thought of shedding their human skins and trading them for the furred body, and simply regard the painful transformation as the price to pay for the power. But going there and back is the one thing no sane werewolf would want to go through willingly. While the pain of the transformation does lessen over time, as practically every one of them states, and the transformation actually does happen faster as werewolves age, this is only true for the first few years after the curse is enacted. The werewolf's body is adapting to the stress of the transformation during that time, but there are limits to this adaptability. After that time has passed, the body has reached its limits of adjustment and the pain stays the same, as does the time it takes to transform.

During the first year, the transformation is agonizingly slow, sometimes dragging itself along for two hours. After about 6 to 7 years, the length of time the transformation takes will decrease to about 30 minutes. After this, there is no known way to further minimize the time it takes to transform, or make the transformation experience less painful. Narcotics either don't work, or if they work they don't work enough to suppress the pain to any significant degree. Any dosage that theoretically could work is definitely lethal.

This cycle of agony causes many werewolves to worry that the repeated pain of transformation will eventually cause them to lose their humanity and turn into monsters. This fear is not unjustified, since many of their kind over the centuries have made pacts with dark forces to get rid of this pain, albeit without any proof of success.

The Spirit:
From a spiritual, or mental, point it is safe to say that the hammremir experiences the full range of human emotions.
However, there is a debate on whether "the wolf" inside a hammramr is actually a separate entity or rather a part of oneself that manifested itself, once the curse was enacted. Both sides cite the mental state of the pre-awakened werewolf as well as the one after the transformation as evidence for their theory. No matter what age, gender or culture, every one of the human werewolves is prone to temper tantrums as children and violent outbursts as teens, albeit with individual differences, based on upbringing and personal choice. Neither of these things is particularly rare, of course, and most adults who are unaware of the pre-awakened state probably just assume the child is spoiled or maladjusted. Nonetheless while some learn strategies to cope with their emotional volatility, others end up medicated or institutionalized.

These anger issues also very often lead to the enactment of the curse as it tends to get the pre-awakened warrior into situations that can lead to death in one way or another. In such instances, some argue that these anger issues are a sign of "the wolf" trying to get out, as well as its frustrations at being caged within the pre-awakened body manifest itself as this anger. Others see these issues as evidence that "the wolf" is not a separate entity but an integral part of the human warrior from birth on and the anger issues are an inherited part of the personality.

This brings us to the state of the werewolf, after the transformation. For the advocates of the "separate wolf" theory, the ravaging of the wolf-form is evidence for a separate entity. And any hazy recollections humans may experience of actions they may have committed while in werewolf form are proof of the human soul being caged in that body who can still manage a peek from time to time to the outside world.

Conversely, for the advocates of the "integral wolf" theory, these hazy memories are regarded as evidence that human and wolf are not separate beings. After all, how could two personalities be active at the same time? They argue that the wolf-state is similar to other extreme emotional and mental states, where people act and react on pure instinct and/or emotion; or to cases of people being influenced by drugs or alcohol to the point of blackout, who also have no or no clear recollections of what happened , yet they were still the same beings just influenced by a new factor. For them, the full moon is that new factor that triggers a behavioral change in the warrior.

The emotional changes after the enactment of the curse are connected to the nature of the non-human part of the human warrior. Usually these urges are considered part of the nature of a wolf. However, this is not the truth. No matter whether you see "the wolf" as separate or integral, that newly awakened part of the human werewolf is not the same in all the warriors. Rather, each is as much an individual as the warrior itself, and is not entirely different than the human. In fact, in can be argued whether "the wolf" is really a representation of a wolf's nature, or rather that of a human or a chimpanzee. This is possible, since some of the warriors are extremely violent, while others are (nearly) non-violent in human form. The average warrior is between these two extremes. This, of course, calls to mind the nature versus nurture debate, with respect to the werewolves' human genetics and upbringing.

In any case, at first, these "new" urges and especially the warrior's violent nature are difficult to control, or to manage depending on the perspective. It typically takes a few years for a warrior to become reasonably safe to be around, in situations that result in psychological stress. Even afterwards, it can be difficult not to give into the urge to simply hit every sort of opponent.

Newly turned individuals, especially teenage ones, often have especially strong trouble in dealing with these urges as well as their increased strength, ending up doing inhumanly high jumps during sports, breaking locker doors and door knobs and attacking other people nearby seemingly for no good reason. Especially during these times, their anger rises ,they have difficulty controlling their power, and, as a result, more than one has found himself having unwittingly killed his opponent.
In addition the influence of "the wolf" becomes stronger a few days before and after the full moon. Nonetheless, the werewolves' urges are always present, and some warriors go so far as to actually speak to "the wolf" inside of them.

One interesting aspect of werewolf-ism is the notion of imprinting. Werewolves are often hard wired to "imprint" on a certain enemy. They then can pass this encoded image to their descendents, resulting in their wolf-forms attacking this sort of enemy above all others, when given the chance.
